If the terms of the contract are uncertain or incomplete, the parties cannot have reached an agreement in the eyes of the law. An agreement to agree does not constitute a contract, and an inability to agree on key issues, which may include such things as price or safety, may cause the entire contract to fail.
As we said earlier, a contract should always foresee the possibility of nonperformance, intentional or unintentional, and should spell out what is to be done. Some contracts go so far as to include an agreement on a set amount of liquidated damages which are to be paid in case something goes wrong.
