Cosigner vs guarantor — what it means and how it varies by state

Cosigners and guarantors both assume responsibility for a tenant's lease obligations, but the legal relationship is different. Cosigners are co-tenants on the lease; guarantors are not on the lease but are liable if the tenant defaults.

§ I — What "cosigner" and "guarantor" mean

A cosigner signs the lease itself and becomes a co-tenant — equally responsible for rent and capable of being sued for non-payment alongside the primary tenant. A guarantor signs a separate guaranty agreement and is only liable when the primary tenant defaults; the landlord must usually exhaust remedies against the tenant first. The choice between the two affects credit reporting, eviction procedures, and the order in which the landlord can recover unpaid rent.
