Lease Signing Requirements: Legal Steps to Make Your Rental Agreement Enforceable

A rental lease isn't legally binding just because you put words on paper. Proper execution requires specific legal steps that many landlords and tenants overlook, leading to unenforceable agreements and costly disputes.

This guide covers the essential requirements for legally signing rental leases, ensuring your agreement holds up in court and protects both parties.
