A guarantor lease amendment is a legal document that is added to a current lease to make a non-tenant party liable for the tenant’s responsibilities. A guarantor is making a “guarantee,” and agrees to co-sign for the same terms and conditions as the tenant.

A common example is when the tenant fails to pay rent, the guarantor becomes obligated to pay the landlord.

Commonly Used When

The tenant is not approved by the landlord to sign a lease on their own. A third party, the “guarantor,” agrees to be obligated to any of the lease terms if the tenant defaults.
