How to share income after marriage and kids?
"My suggestion would be that you're looking at this the wrong way, though for good reasons.  Once you are a family, you should - and, in most cases I've seen, will - think of things differently than you do now. Right now, your post above is written from a selfish perspective.  Not to be insulting, and not implying selfish is a bad thing - I don't mean it negatively.  But it is how you're defining this problem: from a self-interested, selfish point of view.  ""Fair"" and ""unfair"" only have meaning from this point of view; something can only be unfair to you if you come from a self-centered viewpoint. Try to think of this from a family-centric viewpoint, and from your significant other's point of view. You're absolutely right to want both of you to be independent financially as far as is possible; but think about what that means from all three points of view (your family's, yours, and hers)? Exactly what it means will depend on the two of you separately and together, but I would encourage you to start with a few basics that make it likely you'll find a common ground: First of all, ensure your significant other has a retirement account of her own that is funded as well as yours is.  This will both make life easier if you split up, and give her a safety net if something happens to you than if you have all of the retirement savings.  I don't know how your country manages pensions or retirement accounts, but figure out how to get her into something that is as close to equal to yours as possible. Make sure both of you have similar quality credit histories.  You should both have credit cards in your own names (or be true joint owners of the accounts, not just authorized users, where that is possible), and both be on the mortgage/etc. when possible.  This is a common issue for women whose spouse dies young and who have no credit history.  (Thanks @KateGregory for reminding me on this one) Beyond that, work out how much your budget allows for in spending money for the two of you, and split that equally.  This spending money (i.e., ""fun money"" or money you can do whatever you like with) is what is fundamentally important in terms of financial independence: if you control most of the extra money, then you're the one who ultimately has control over much (vacations, eating out, etc.) and things will be strained.  This money should be equal - whether it is literally apportioned directly (each of you has 200 a month in an account) or simply budgeted for with a common account is up to you, whatever works best for your personal habits; separate accounts works well for many here to keep things honest. When that money is accounted for, whatever it is, split the rest of the bills up so that she pays some of them from her income.  If she wants to be independent, some of that is being in the habit of paying bills on time.  One of you paying all of the bills is not optimal since it means the other will not build good habits.  For example, my wife pays the warehouse club credit card and the cell phone bill, while I pay the gas/electric utilities. Whatever doesn't go to spending money and doesn't go to the bills she's personally responsible for or you're responsible for (from your paycheck) should go to a joint account.  That joint account should pay the larger bills - mortgage/rent, in particular - and common household expenses, and both of you should have visibility on it.  For example, our mortgage, day-care costs, major credit card (which includes most of our groceries and other household expenses) come from that joint account. This kind of system, where you each have equal money to spend and each have some household responsibilities, seems the most reasonable to me: it incurs the least friction over money, assuming everyone sticks to their budgeted amounts, and prevents one party from being able to hold power over another. It's a system that seems likely to be best for the family as a unit.  It's not ""fair"" from a self-centered point of view, but is quite fair from a family-centered point of view, and that is the right point of view when you are a family, in my opinion. I'll emphasize here also that it is important that no one party hold the power, and this is set up to avoid that, but it's also important that you not use your earning power as a major arguing point in this system.  You're not ""funding her lifestyle"" or anything like that: you're supporting your family, just as she is.  If she were earning more than you, would you cut your hours and stay at home?  Trick question, as it happens; regardless of your answer to that question, you're still at the same point: both of you are doing the thing you're best suited for (or, the thing you prefer).  You're both supporting the family, just in different ways, and suggesting that your contribution is more valuable than hers is a great way to head down the road to divorce: it's also just plain incorrect.  My wife and I are in almost the identical situation - 2 kids, she works part time in the biological sciences while spending plenty of time with the kids, I'm a programmer outearning her significantly - and I can tell you that I'd more than happily switch roles if she were the bread earner, and would feel just as satisfied if not more doing so. And, I can imagine myself in that position, so I can also imagine how I'd feel in that position as far as how I value my contribution." You remind me a lot of myself as I was thinking about marriage. Luckily for me, my wife was much smarter about all this than I was. Hopefully, I can pass along some of her wisdom. Both of us feel very strongly about being financially independent and if possible we both don't want to take money from each other. In marriage, there is no more financial independence. Do not think in those terms. Life can throw so many curve balls that you will regret it. Imagine sitting down with your new bride and running through the math. She is to contribute $X to the family each month and you are to contribute $Y. Then next thing you know, 6 months later, she has cancer and has to undergo expensive and debilitating treatment. There is no way she can contribute her $X anymore. You tell her that is okay and that you understand, but the pressure weighs down on her every day because she feels like she is not meeting your expectations.  Or alternatively, everything goes great with your $X, $Y plan. A few years down the road your wife is pregnant, so you revisit the plan, readjust, etc. Everything seems great. When your child is born, however, the baby has a severe physical or mental handicap. You and your wife decide that she will quit her job to raise your beautiful child. But, the whole time, in the back of her mind she can't get out of her head that she is no longer financially independent and not living up to your expectations. These stresses are not what you want in your marriage. Here is what we do in my family. Hopefully, some of this will be helpful to you. Every year my wife and I sit down and determine what our financial goals are for the year. How much do we want to be putting in retirement? How much do we want to give to charity? Do we want to take any family vacations? We set goals together on what we want to achieve with our money. There is no my money or her money, just ours. Doesn't matter where it comes from. At the beginning of every month, we create a budget in a spreadsheet. It has categories like (food, mortgage or rent, transportation, clothing, utilities) and we put down how much we expect to spend on each of those. It also has categories for entertainment, retirement, charity, cell phones, internet, and so on. Again, we put down how much we expect to spend on each of those. In the spreadsheet, we also track how much income we expect that month and our totals (income minus expenses). If that value is positive, we determine what to do with the remainder. Maybe we save some for a rainy day or for car repairs. Maybe we treat ourselves to an extra fancy dinner. The point is, every dollar should be accounted for. If she wants to go to dinner with some friends, we put that in the budget. If I want a new video game, we put that in the budget. Once a week, we take all our receipts and tally up where we spent our money. We then see how we are doing on our budget. Maybe we were a little high in one category and lower than expected in another. We adjust. We are flexible. But, we go over our finances often to make sure we are achieving our goals. Some specific goals I'd recommend that the two of you consider in your first such yearly meeting: You get out of life what you put into it, and you will get out of your finances what the two of you put into them. By being on the same page, your marriage will be much happier. Money/finances are one of the top causes of divorce. If you two are working together on this, you are much more likely to succeed. I started out thinking like you but I quickly realised this was a bad approach. You are a team, aren't you? Are you equals or is one of you an inferior of lower value? I think you'll generate more shared happiness by acting as a team of equals. I'd pool your resources and share them as equals. I'd open a joint account and pay both your incomes directly into it. I'd pay all household bills from this.  If you feel the need, have separate personal savings accounts paid into (equally) from the joint account.  Major assets should be in joint names. This usually means the house. In my experience, it is a good idea to each have a small amount of individual savings that you jointly agree each can spend without consulting the other, even if the other thinks it is a shocking waste of money. However, spending of joint savings should only be by mutual agreement. I would stop worrying about who is bringing in the most income. Are you planning to gestate your children? How much is that worth? - My advice is to put all this aside, stop trying to track who adds what value to the joint venture and make it a partnership of equals where each contributes whatever they can. Suppose you fell ill and were unable to earn. Should you wife then retain all her income and keep you in poverty? I really believe life is simpler and happier without adding complex and stressful financial issues to the relationship. Of course, everyone is different. The main thing is to agree this between the two of you and be open to change and compromise. "I haven't seen this addressed anywhere else, so I'll make a small answer to add on to the great ones already here. Money isn't the only way a person can contribute to a relationship. Time and effort are valuable contributions. Who runs the household? Who cooks, cleans, does laundry? How will you share these duties? My husband and I have a couple of rules. One of which is that we don't keep count. ""I did dishes, so you do laundry"". ""I made coffee last time, so now it's your turn"". ""I paid this, so you pay that"". That's not allowed.  I happen to make ~4x as much as my husband, but I work 4x the hours (he's part time at the moment). So, he does the dishes, he cooks, he does laundry, he runs the household. Do I value him less? No! I value him more, because he is part of the team, and he feeds me coffee while I work (we have our own business). Even though I make so much more than him, we still split everything down the middle. Because his contribution to this relationship, to this household, is so much more than just money. And I value him. I value his contribution.  At the end of the day, you are a team - and if you split hairs over finances, you'll find yourself splitting hairs over everything." Now I have been trying to figure out how to split the money that we both earn. From what I can see there are several concepts but none of them really seems ideal to me. There is nothing fair or unfair in such arrangements. It is what you both agree. You can try and make this as scientific as possible. But then there is no golden rule.  For example, your girlfriend makes 2200 now and due to child, she is making 1100. The child is both of your responsibility; so you need to compensate half of her salary loss. 550 and she takes the other half. If you hire a nanny to look after you kinds, it would say cost you 500. But your girlfriend is doing that job, so she should get additional 500 from common pot. Plus due to loss of few years in looking after the children, she has a lost opportunity in career growth. i.e. she may indefinitely make less money than she can... So one gets into all kinds of theories and analysis and any arrangements will have some or the other gaps.  So my suggestion, don't get too scientific about it. Just talk it out as to what you both feel how this should be and arrive it. It is something every individual has to agree. It also make sense to have the large assets [or assets that matter], like house, car etc in clear title and who gets what in case you decide to separate. Other should be incidental. I started this off as a comment to Joe's answer, but it got rather messy in that form so I'll just post it as a separate answer instead. I suggest that you read Joe's answer first. I believe you are overthinking this. First, you really should be discussing the matter with your girlfriend. We can provide suggestions, but only the two of you can decide what feels right for the two of you. Strangers on the Internet can never have as complete a picture of your financial situations, your plans, and your personalities, as the two of you together. That said, here's a starting point that I would use as input to such a discussion: As you can see, a common theme to all of this is transparency and communication. There is a reason for this: a marriage without proper communication can never work out well in the long term. I don't know about Germany specifically, but disagreements about money tends to be a major reason in couples splitting up. By setting your lives up for transparency in money matters from the beginning, you significantly reduce the risk of this happening to you. Scott Hanselman discusses a very similar way of doing things, but phrases it differently, in Relationship Hacks: An Allowance System for Adults. I won't answer in a detailed manner because most people at this site like answers with certain bias' on these questions, like pool resources always relative to which partner is asking.  If you follow the above advice, you are hoping things work out.  Great!  What if they don't?  It will be very messy.  Unlike most of my peers, I did NOT follow the above advice and had a very clean exit with both of us feeling very good (and no lawyers got involved either; win-win for both of us with all the money we saved). One assumption people make is the person with the lowest income has the strictest limits.  This is not always true; I grew up in poverty, but have a very high income and detest financial waste.  I can live on about €12,000 a year and even though my partner made a little less, my partner liked to spend.   Counter intuitive, right?  I was supposed to be the spender because I had a large income, but I wasn't.  Also, think about an example with food - sharing expenses.  Is it fair for one partner to split whey protein if one partner consumes it, but the other doesn't (answer: in my view, no)? My advice based on your questions: Balance the frugal vs. spendthrift mentality rather than income ratios.  If you're both frugal, then focus on income ratios - but one may be more frugal than the other and the thought of spending €300 a month on housing is just insane to a person like me, whereas to most it's too little.  Are you both exactly the same with this mentality - and be honest? Common costs that you both agree on can be easily split 50-50 and you can often benefit from economies of scale (like internet, cell phone). Both of us feel very strongly about being financially independent and if possible we both don't want to take money from each other. This is so healthy for a relationship.  My partner and I split and we both still really love each other.  We're headed in different directions, but we did not want to end bitterly.  What you wrote is part of why we ended so well; we both were very independent financially.   Kids are going to be a challenge because they come with expenses that partners don't always agree on.  What do you and her think of childcare, for instance?  You really want to know all this upfront; again a frugal vs. spendthrift mindset could cause some big tensions. "I think you have succumbed to a category error. The rational course forward is to classify all property as either his, hers, or family's. Each contributes a portion of wages to the family. Each logs hours spent performing familial duties and is ""paid"" in virtual dollars into their family account at market rates for that service. At any point actual plus virtual dollars are summed to assess the value of the family and percentages are allocated to each party on this basis. Put this into a pre-nuptual agreement.  At the time of the inevitable divorce you leave with yours, she leaves with hers, family's assets are divided as described, and division of children should be as King Solomon suggested. Or you could do what I did: Put all your property (and debts) into one pot. Make sure each partner can competently manage bookkeeping and investments. Accumulate a family net worth sufficient to divide in two and each have financial independence. (I'm working on this last step.)" "I can only share with you my happened with my wife and I. First, and foremost, if you think you need to protect your assets for some reason then do so. Be open and honest about it. If we get a divorce, X stays with me, and Y stays with you.  This seems silly, even when your doing it, but it's important. You can speak with a lawyer about this stuff as you need to, but get it in writing. Now I know this seems like planning for failure, but if you feel that foo is important to you, and you want to retain ownership of foo no mater what, then you have to do this step. It also works both ways. You can use, with some limitations, this to insulate your new family unit from your personal risks. For example, my business is mine. If we break up it stays mine. The income is shared, but the business is mine. This creates a barrier that if someone from 10 years ago sues my business, then my wife is protected from that. Keep in mind, different countries different rules. Next, and this is my advise. Give up on ""his and hers"" everything. It's just ""ours"". Together you make 5400€ decide how to spend 5400€ together. Pick your goals together. The pot is 5400€. End of line. It doesn't matter how much from one person or how much from another (unless your talking about mitigating losses from sick days or injuries or leave etc.). All that matters is that you make 5400€. Start your budgeting there.  Next setup an equal allowance. That is money, set aside for non-sense reasons. I like to buy video games, my wife likes to buy books. This is not for vacation, or stuff together, but just little, tiny stuff you can do for your self, without asking  ""permission"". The number should be small, and equal. Maybe 50€.  Finally setup a budget. House Stuff 200€, Car stuff 400€. etc. etc. then it doesn't matter who bought the house stuff. You only have to coordinate so that you don't both buy house stuff. After some time (took us around 6 months) you will find out how this works and you can add on some rules. For example, I don't go to Best Buy alone. I will spend too much on ""house stuff"". My wife doesn't like to make the budget, so I handle that, then we go over it. Things like that." "My own personal point of view. I earn about twice what my wife to be earns. We are planning on getting married next year.  I ultimately do all the finances (basically because she hates that kind of thing) not because I'm in charge or whatever. To work out how we do this I wrote a spreadsheet:  At the top it has my monthly pay in one column and her's in another. I add all our bills (against me initally). At the bottom I have a total of both of our ""spending money"". Spending money is wage - bills - savings I then move money out of my column into her column. My goal is that we pay all the bills and save a decent amount and have roughly the same amount to spend each month. So each persons spending money should be roughly equal. I then fine tune this as things change (if we get a pay rise we alter it, if a bill goes up or down we alter it) To manage this we have 4 accounts, a joint account to pay bills (both give a set amount to each mont), a savings acount (both give a set amount to each month) and our own accounts (where we get paid and where our spending money lives). Like everyone else says, this seems fair to me. I don't earn more, we both earn ""an amount"" and this should be split equally." You currently have 5400€ between you and 2600€ expenses leaving you 2800€. You currently keep 1900€ and she keeps 900€ at the end of each month splitting 68/32. If you marry and have a child, your combined income will go down to 4900€ while your expenses will increase by 300€ to 2900€ leaving 2000€. You could continue to split 68/32 leaving you 1360€ and her 640€. If you use this split you will lose 540€ and she will lose 260€. That's a 28% loss for you and a 28% loss for her from your end of month take home. So far it sounds reasonably fair. What about the future? For each raise, the person getting the raise keeps 66% of their raises. If you get the majority of the raises, you keep the majority of the benefit, but both benefit from the increase. Any future increases in expenses can be split as negotiated based on who benefits from those increases. That's basically what you are doing now considering that adding a child will cost a lot of her time, not just your money. "Some basic thoughts, mostly on fairness. I guess the answer doesn't really fit this site, it's more about ethics, but this fits the question which isn't really just about money either. So when both work the same amount, it seems appropriate that both get the same mount of money, doesn't it? That is, the scheme of (as already contained in your question and in some other answers) is fair by this logic. Pay attention to hidden money: for example the one who works more for money might automatically get a pension funded this way. This is hidden money which already goes to only one partner, so when dividing equally, you'll need to take that into account (or just include ""equal pensions for both"" in the family's needs directly)." This would be my suggestion: I would approach the problem thinking about the loss of monthly income you (as a couple) will be facing due to your wife's change to a part time job and divide that loss between the two of you. This means that if she goes from 2200 to 1100 monthly, you'd be losing 1100 per month.  To share this loss, you could repay your wife your part of the loss (550) so both of you are 550 euro down. However, this 550 loss is a bigger burden for your wife than it is for you, so this amount could be adjusted to make up for this inequality.  To make calculations simple and avoid developing a complicated model, you could give the 800 euro above your 3k to your wife for as long as she has to work part time. What equal percentage of both you and your girlfriend's income will cover the essential household expenses? Although we earned different amounts, both of us turned over half our income over to the household.  Between us this percentage slice from each of our earnings neatly covered all the essentials.  The amounts contributed were different, but the contributions where nonetheless equal. Beyond this the financial relationship was fast and loose. The bottom line is choosing the right partner. If your partner works as hard as you do, than everything should be split, irregardless of who makes more. Unfortunately, my bf, now by separated husband, borrowed money from me before we were married. I saw a lack of work ethic in him from the beginning, loved him anyway and married him but decided to keep my money separate as a result. This was a beginning with lack of trust and knowing I would be the higher earner, harder worker, and better provider. Down the road he won a lawsuit and got about $700k. I saw about $25k of this money to pay bills created with the intention of him paying them off when he got the money, and because he pilfered it away, we lost our house and it ended in my leaving.... I'm still doing ok because I work hard for what I have. He is struggling. We were never on the same page, never discussed finances because of his lack of work ethic and my mistrust of how he would decide how the money would be used. Sadly, who you decide to be your partner is the most important decision here...It should be based on mutual respect, both working hard to achieve a common goal, and communicating the budget every year, perhaps even each month.... I'm the terrible example. "I think the problem is that you've made a math error. This child would not be costing you 300 per month, it will be costing you 1400 per month.  1100 of this is in a donation of salable hours rather than cash, but helpfully you have a number right there as to how much someone is willing to pay for these hours so the math is still doable. So, if you are indeed splitting your expenses fifty-fifty, you should chip 1100 into the pot to match your wife's contribution.  It would make the most sense, I think, to have your part of this contribution cover some of your mutual expenses, and if any is left over, save it up for the day that your child would cost more than that 300 in a month - when you need extra clothes, or have to replace something they destroyed, or want to pay for extra opportunities (camps, educational games, lessons), or a a savings that can be used for major future expenses (higher education, first car, milestone celebrations, safety net when starting out). Of course, if your family is indeed a priority, you might consider making an equal investment in your family - say, half your income (1800) to match half her time going into the building of the family.  After all, the decision to start a family should be an investment of time and value, not just a minimum bid for expenses.  And again, any extra can be spent on mutual expenses, saved up for future costs, or left as your child's ""savings"" for major expenses or safety net. I suppose I should mention that you perhaps could get away with covering half her contribution (550 per month, on the face of it), as that should also ""balance"" out the monthly expenses.  Even this much would be enough to put her back into the green on her covering her own costs.  Of course, in this case you might want to take into account that while she's working 38,5 hours per week now, running a household is, I've heard, more closely equivalent to a 60-hour week, plus or minus being ""on call"" for a further 100 hours a week.  Trying to calculate the absolute minimum payment on your part to match the investment of hours on hers is likely to be a bit more tricky than just matching the salable hours not worked, if you're set on income ratios and splitting costs ""as they are"". Also, you might want to rethink your criteria for sharing income completely or what makes certain divisions of costs ""unfair"". You mention one reason it would be unfair is that you have a ""more stressful job"" - well, your job may well be more stressful than her job now, but it is likely to be less so than raising a child (her new job).  As for investment of time and energy for your education entitling you to a larger amount of pay, again, raising a child is likely to be a larger investment of time, money, and anxiety than your education, but her pay (or even share of the costs) doesn't seem to be balanced in response.  I'm not gonna tell you what is fair, that's for you to work out, just suggesting you really think it through before deciding what would be fair or not."
Wow! First, congratulations! You are both making great money. You should be able to reach your goals.  Are we on the right track ? Are we doing any mistakes which we could have avoided ? Please advice if there is something that we should focus more into ! I would prioritize as follows: Get on the same page. My first red flag is that you are listing your assets separately. You and your wife own property together and are raising your daughter together. The first thing is to both be on the same page with your combined income and assets. This is critical. Set specific goals for the future. Dreaming and big-picture life planning will be the foundation for building a detailed plan for reaching your goals. You will see more progress with more sacrifice. If you both are not equally excited about the goals, you will not both be equally willing to sacrifice lifestyle now. You have the income now to be able to set yourselves up to do whatever you want in 10 years, if you can agree on what you want. Hire a financial planner you trust. Interview people, ask someone who is where you want to be in 10 years. You need someone with experience that can guide you through these questions and understands how to manage your income stream. Start saving for retirement in tax-advantaged accounts. This should be as much as 10%-15% of your income combined, so $30k-$45k per year. You need to start diversifying your investments. Real estate is great, but I would never recommend it as this large a percentage of net worth. Start saving for your child's education. Hard to say what you need here, since I don't know your goals. A financial planner should assist you with this. Get rid of your debt. Out of your $2.1M of rental real estate and land, you have $1.4M of debt. It will be difficult to start a business with that much additional debt. It will also put stress on your retirement that you don't need. You are taking on lots of risk here. I would sell all but maybe one of the properties and let it cash flow. This will free up cash to start investing for retirement or future business too. Buy more rental in the future with cash only. You have plenty of income to do it this way, and you will be setting yourself up for a great future. At this point you can continue to pile funds into any/all your investments, with the goal of using the funds to start a business or to live on. If all your investments are tied up in real estate, you wont have anything to draw on if needed for a business opportunity. You need to weigh this out in your goal and planning. What should we do to prepare for a comfortable retirement and safety You cannot plan for or see all scenarios. However, good planning will give you more options and more choices. Investing driven by fear will set you up for failure.  Spend less than you make. Be patient. Be generous. Cheers! Other than the two answers (both of which recommend waiting until marriage to actually combine finances, and which I agree with), there's the general question:  how does a couple choose to manage finances? In our marriage, it's me.  I'm more numbers-minded than my spousal-unit.  I'm also more a sticker for time.  I work and spousal-unit does not. We had some good friends -- upon marriage, spouse1 felt like he should take on the role.  He went on a several-week trip (leaving spouse2 at home), and upon returning home asked spouse2 about the late fees.  Spouse2 was appalled.  Spouse2 ended up keeping the job of managing household finances. There's enough pieces to the puzzle that it can be divided any way you choose -- any way that works for you and your spouse/virtual-spouse. One other point:  talk about how to manage your money, before you marry.  Dave Ramsey recommends a strict monthly budget.  I like listening to Dave Ramsey, but we've never had a budget.  Instead, we agreed during marriage counseling two things: "I don't think it would be counted as income, and if it's a short-term loan it doesn't really matter as the notional interest on the loan would be negligible. But you can avoid any possible complications by just having two accounts in the name of the person trying to get the account benefits, particularly if you're willing to just provide the ""seed"" money to get the loop started." "My wife and I use to file ""married file separately"".  I consulted a tax accountant and it does not matter who's name the accounts are under.  The interest from the accounts can be counted as income on either person's tax return regardless of whose name is on the account.  You can even split the interest income between the returns if that is advantageous.  This is true for any income earned between the two of you. It use to be a big hassle to file this way even using the software programs.  The programs would not attempt to allocate the income between the tax returns in order to minimize my tax liability.  I had to do this manually.  Most of the loopholes have been closed and the last couple of years I've filed ""married filed jointly"". I'm not sure how your wife's citizenship status affects any of this." has very little idea about how much we earn and how high up we are in terms of income percentile. The first part of this sentence is tough to understand. My daughter was 12 when she told us what she estimated our income to be. She looked up the price of our home, worked backwards using conservative numbers, and was pretty close. Here you are saying your wife doesn't know the family income?  Percentiles are meaningless. There are $60k couples who donate 10%, and there are $300k earners who are not charitable at all, and don't even save.  It's time to have a general budget conversation with her. Perhaps starting with the rate of savings, and show how there's room for charity. If your charitable desire is based on a religious compulsion, share that as well, the 10% is what many feel commanded to share by their maker, and feel that it comes off the top regardless of their income level.  In reality, this issue is not financial, it's about open dialog between 2 people. Money is difficult for some to discuss, but you need to start somewhere. I can't quite follow your question, so I'm proceeding under the following assumptions: - You paid £31,000 - Your partner paid £4,242 - You have at least one mortgage, which you both pay equally. If the relationship terminates, sell the property. You are reimbursed £31,000 and your partner is reimbursed £4,242. Any remaining proceeds from the sale are split 50-50. If the result is a net loss (i.e. you are underwater on your mortgage), you split the debt 50-50. If you are not both paying the same toward the mortgage, I'd split the profit or loss according to how much you each pay toward the mortgage. Of course, this is not the only possible way you can split things up. You can use pretty much any way you both think is fair. For example, maybe you should get more benefits from a profit because you contributed more up-front. The key thing, though, is that you must both agree in writing, in advance. This is reasonable; this is what I did, for example. Note that if the relationship ends, one or the other of you may wish to keep the property. I'd suggest including a clause in your written agreement simply disallowing this; specify criteria to force a sale. But I know lots of people are happy to allow this. They treat that situation as a forced sale from both people to one person. For example, if your partner chooses to stay in the house, he or she must buy the property from you at prevailing market rates. "(Yes, I know this is a seven year old question.) Does this only apply to debts that were taken on during marriage  Yes or to all debts of both partners? No. The important thing to remember is that it's both debts and assets acquired during the marriage which are shared. This comes from the reality that men in the olden times were the ones in business, accumulating wealth, etc while the woman ""made the home"".  The working assumption was that the woman who made the home was an equal partner with the man, since he benefited from a good home, and she benefited from his income. The fact that pre-marriage debts and assets were not community property also protected the woman, because she was able to then take back her dowry and use that to support herself. (N.B. - I live in a CP state.)" "Do you have other income that you are not considering?  Interest and dividends would be an example, but there are all sorts of options.   Also with your witholding is it set up such that your employers have any idea of your tax bracket ultimately based on your combined incomes?  Usually what they do is take out money assuming you will be in the tax bracket of any given paycheck spread out over the course of a year.  For example, for federal I had an option to select (in an online form that fills out my W4 for me) ""married: withold at higher single rate"" and did to try and cover this fact.  Eventually I may end up having to calculate my own witholding to fix a too-low problem like yours." "If my wife and I tried this, we'd call it grounds for divorce. However, I think most long term couples actually do this, and it is just a budget.  It is common practice for two spouses to deposit money into a single checking account.  All of the household expenses are then paid from that single account.  Same as you describe: if I spend money from the joint checking that is less money available to my wife. Based on your dollar amount, I'd have to say great work on thinking about saving early on in life.  I think though, if you are actually starting out, getting into the habit of saving a ""dime of every dollar"" would be more beneficial. At some point your income will increase, and when it does so should your savings.  By ""paying yourself first"" your savings will keep pace with your spending and you will be a happier person when you income starts to fall again." "If you have a huge disparity in incomes, ""maybe"".   If you make roughly in the same ballpark, **Noooooo!**   The ability to file separately and have one partner (the higher earner) itemize and claim all the home-related deductions while the other takes the standard deduction is one of the greatest (middle-class) loopholes in modern tax law.  When married, even if filing separately, you have to both itemize or both take the standard deduction.   You just need to take care that the person itemizing has provably contributed *at least* the amount they claim toward the house.  So have one of you write the checks for the mortgage and property tax, and the other pay for everything else, and it'll probably come out roughly even over time.  Going back to my first line, the US tax code seems to be designed around the stereotypical Donna Reed 1950s household, with a single earner.  The closer you are to equal, the bigger the marriage tax **penalty** gets." It depends on where you live and how you can think out of the box on earning little extra income on the side. If  you live in North America and based on the needs in your city, you can try out these ideas. Here is what one of my friend has done,  The family has two kids and the wife started a home day care as she was already taking care of two kids anyways. Of course, she had to be qualified and she took the relevant child care classes and got certified, which took six months. And she is managing 4 kids in addition to her two kids bringing in at least 2000$ per month in addition. And my friend started a part time property management business on the side, with one client. For example there is always work on real estate whether its going up or going down. You have to be involved locally to increase your knowledge on real estate. You can be a property manager for local real estate investors. If its going down, you can get involved in helping people sell and buy real estate. Be a connector, bring the buyers and sellers together. "If you ask ten different couples what they do, depending on a variety of factors, you'll get anywhere between two and ten different answers. One personal finance blogger that I read swears by the fact that he and his wife keep their finances totally separate.  His wife has her own retirement account, he has his.  His wife has her own checking and savings, he has his.  They pay fifty-fifty for expenses and each buy their own ""toys"" from their own accounts.  He views this as valuable for allowing them to have their own personal finance styles, as his wife is a very conservative investor and he is more generous. My spouse and I have mostly combined finances, and view all of our money as joint (even though there are a smattering of accounts between us with just one name on them as holdovers from before we were married).  Almost all of our purchasing decisions except regular groceries are joint.  I couldn't imagine it any other way.  It leaves us both comfortable with our financial situation and forces us to be on the same page with regards to our lifestyle decisions.  There's also the ideological view that since we believe marriage united us, we try to live that out.  That's just us, though.  We don't want to force it on others. Some couples find a balance between joint accounts and his and her fun money stashes.  You might find yet another arrangement that works for you, such as the one you already described. What's going to be important is that you realize that all couples have the same six basic arguments, finances being one of them.  The trick is in how you disagree.  If you can respectfully and thoughtfully discuss your finances together to find the way that has the least friction for you, you're doing well.  Some amount of friction is not just normal, it's almost guaranteed." hmmm. I think it's because in both cases, you must pay for it up front, before the positions are closed out. You own nothing except the right to buy the stock re: the call, and the obligation to buy the stock re: the short.  You buy a call, but must borrow the stock, for which you must put some margin collateral and there is a cost to borrow. You pay for that, of course.  I wouldn't call it lending though. If they're making 100k a month in sales, why do they need your 92k so badly that they're willing to pay 200% annual interest? Going to a loanshark or the mob would be cheaper, to say nothing of all the legal options available to them. Or they could just wait three weeks for revenue to cover it. Nothing about this adds up to anything other than a scam. Your friend might be well-meaning, but someone along the line is looking for a sucker.
