Yes, a contract can be valid and enforceable even if not signed by both parties, especially if their actions, conduct, emails, or partial performance show they agreed to the terms, but it's much riskier and harder to prove than a signed contract. While signatures are best for clarity, a court can find a binding agreement through evidence of offer, acceptance, and consideration, often established by behavior like starting work or accepting benefits, creating an "implied contract".

You generally cannot cancel a signed contract easily, as it's legally binding, but you might be able to if there's a specific "cooling-off period" (like for some door-to-door sales, timeshares, or home loans), a termination clause in the contract, mutual agreement, or if the other party significantly breached the terms, committed fraud, or there was mutual mistake.
