## Definition

describing a rule, law, or contract that cannot be made to happen or followed. It is often used when a court says a rule is not fair or legal.

For teachers: incapable of being made effective or carried out; legally unbinding. Often describes a contract or clause that a court has ruled invalid or unenforceable due to public policy or lack of consideration.

## Examples

- The court ruled that the contract was unenforceable.
- Because the two parties did not sign the agreement, the terms of the deal became unenforceable in a legal dispute.
- While the clause was technically included in the lease, it was deemed unenforceable as it attempted to waive the tenant's right to a safe living environment, which is protected by local housing laws.
