Sometimes a contract may be valid yet unenforceable.

As a general rule,a valid contract is one that will be enforced.However,sometimes a contract may be valid yet unenforceable.A valid contract may be unenforceable when some law prohibits the courts from enforcing it.For example,the statute of frauds requires certain contracts to be evidenced by a writing before they can be enforced.Similarly,the statute of limitations mandates that an action for breach of contract must be brought within a set period of time,thereby limiting the enforceability of the contract.
