Cosigner Agreement (Addendum to the Rental Agreement )

With a good cosigner agreement, you spell out the cosigner's liability, cover subleases or assignments, and more.

If you need to create a cosigner agreement as an addendum to a residential lease or rental agreement, see the following legal forms. We've got professional, customizable, digital forms, and a free boilerplate template.

Professional Forms

These digital forms, provided by Nolo, are legally valid in your state, customizable to suit your needs, professionally written, and regularly updated by expert attorneys. Use these if you need to create an enforceable contract.

Free Basic Form Template

The cosigner agreement form below is a very basic one, using boilerplate language, and is intended for educational purposes only. It has not been vetted by an expert, or recently updated. It may not be legally valid.



Date: ___________________

This agreement is attached to and forms a part of the Rental Agreement dated ____________, ______ between _____________________________, Landlord, and _________________________, Tenant(s).

My name is _______________________________ (Cosignor). I have completed a Rental Application for the express purpose of enabling the Landlord to check my credit. I have no intention of occupying the dwelling referred to in the Rental Agreement above.

I have read the Rental Agreement, and I promise to guarantee the Tenant(s) compliance with the financial obligations of this agreement.

I understand that I may be required to pay for rent, cleaning charges, or damage assessments in such amounts as are incurred by the Tenant(s) under the terms of this Agreement if and only if the Tenant(s) themselves fail to pay.

I also understand that this Cosigner Agreement will remain in force throughout the entire term of the tenancy, even if the tenancy is extended or changed in its terms.
