This is the main reason I wish I had had a prenup . I don ' t even care about the separate property . What would have been great was to have a written understanding that we intended to make a fair split if it ever came to that . Instead , under the influence of her new boyfriend who was an expert at divorce , she pushed for everything and anything she could get . Even went after the kids ' college savings to support her new lifestyle . Lawyers later told me a prenup would have saved a lot of this aggravation and legal fees . We were both reasonable people when we got together and for most of our marriage . A prenup would have protected me and the kids from the decidedly different person she became under the influence of bad friends and greedy advice .
