A Guaranty Attachment to Lease is a document in which a third party (known as the guarantor) agrees to be liable for the obligations of a tenant under a lease agreement, should the tenant default on its obligations. This document is often used when the tenant is a corporation or other entity, or when the tenant does not have sufficient credit or assets to cover its obligations. There are two types of Guaranty Attachments to Lease: Absolute Guaranty and Limited Guaranty. An Absolute Guaranty is a guarantee that covers all the tenant’s obligations under the lease, including rent, taxes, insurance, and maintenance. A Limited Guaranty only covers the tenant’s obligations related to a specific issue, such as rent or taxes. The Guarantor is typically asked to provide evidence of their ability to pay any obligations they are liable for, such as a financial statement or other proof of creditworthiness.
