Yes, a contract can be valid even if only one party signs it, especially if the other party shows acceptance through actions like performing duties, accepting benefits, or making payments, demonstrating an intent to be bound. While signatures are strong evidence of agreement, modern contract law often focuses on mutual intent and conduct, meaning email exchanges, performance, or partial execution can create a binding contract even without both signatures, though certain agreements (like real estate) may require signatures under the Statute of Frauds.
