Generally, to be legally valid, most contracts must contain two elements: 1  All parties must agree about an offer made by one party and accepted by the other.  Something of value must be exchanged for something else of value. This can include goods, cash, services, or a pledge to exchange these items.
However, some contracts must be in writing to be enforceable. All contracts must include an offer, the acceptance of that offer, and an exchange of value between the parties (which is known as consideration). If any of those elements are missing, the contract will not be valid.
