Is a contract enforceable if not signed by an officer?

A contract may still be enforceable even if it is not signed by an officer, depending on the circumstances and the governing laws. If the contract has been executed by authorized representatives or if it meets the legal requirements for validity, such as mutual consent and consideration, it could still be binding. However, for corporate entities, certain contracts might require officer signatures to be enforceable, particularly if specified by the entity's bylaws or state laws. Always consult a legal professional for specific situations.
