Can a contract be enforced if only one party signed it?

Yes, a contract can be enforced even if only one party has signed it, provided that the other party has accepted its terms through conduct or explicit agreement. For example, if one party performs their obligations under the contract, this may indicate acceptance of the terms by the other party, leading to enforceability. However, enforceability often depends on the specific circumstances, including the nature of the contract and applicable laws. It is advisable to consult legal counsel for specific situations.
