Yes, a contract can be legally binding even if only one party signs it, especially if the other party shows acceptance through actions (performance or accepting benefits), or if it's a unilateral contract (promise for an act), but having both signatures is best for proof, with exceptions like Statute of Frauds requiring signatures for certain agreements (like land sales). A signature signifies intent, but performance and mutual assent can substitute, though proving unsigned agreements is harder.
