Some people mistakenly believe that an oral contract Aisn't worth the paper it's printed on.
But many types of contracts don't have to be written to be enforceable. An example is purchasing an item in a retail store. Your receipt is proof of the contract. As with a written contract, the existence of an oral contract must be proved before the courts will enforce it. An oral contract is usually proved by showing that outside circumstances would lead a reasonable observer to conclude that a contract most likely existed.
