Who must sign a contract?

• A. Only the alarm company
• B. Both parties (you and client)
• C. At least one signature
• D. No signatures required

Answer: (B)

Signing a contract requires mutual assent; the binding agreement is formed when both sides have agreed to the terms and evidenced that agreement with signatures. For alarm services, the client signs to show acceptance of installation, monitoring, fees, term, and responsibilities, and the alarm company signs to commit to providing those services under those terms. A signature from only one party does not bind the other party and therefore isn't a complete contract; without both signatures you may have an offer or an unsigned document, not a final agreement. Having both signatures helps prevent disputes and clearly establishes the rights and obligations for both sides.
