About This All-States Notice
A rental co-signer agreement (also called a guarantor agreement) makes a co-signer personally liable for the primary tenant’s lease obligations. If the tenant fails to pay rent, the landlord can collect from the co-signer for unpaid rent, damages, late fees, attorney fees, and any other tenant obligations. The co-signer is generally liable for the entire initial lease term and may be liable for renewals unless explicitly terminated. State surety law may provide some protections (e.g., release for material lease modifications without co-signer consent). The agreement should clearly define the scope of liability (rent only, rent + damages, or full obligations), the duration (initial term only, all renewals, or lifetime), and the procedure for releasing the co-signer. Best practice: written form, all parties sign, notarization, co-signer reads the master lease, scope of liability stated clearly, explicit duration limit, co-signer consults counsel before signing. Common uses: parents for college-age children, employers for relocating employees, anyone with sufficient credit guaranteeing a tenant with limited credit history.
