Important: This is a general-purpose template provided for convenience under the Tentunit Templates Disclaimer & Jurisdiction Notice. It is not legal advice and is not state-specific unless expressly labeled. Landlord–tenant requirements (notice periods, day counts, service methods, disclosures) vary by jurisdiction and change over time. Verify against current local law — or consult a licensed attorney — before use. Complete every [BRACKETED FIELD] and delete instructions in italics before sending.

Use this agreement when a third party guarantees a tenant’s lease obligations. Have the guarantor sign before or at lease signing, and attach it to the lease. Some jurisdictions limit guarantor requirements or fees for screening — verify locally. Delete all italic instructions before signing.

1. Parties and Guaranteed Lease

This Co-Signer (Guarantor) Agreement (“Guaranty”) is made on [DATE] by:

  • Guarantor: [GUARANTOR FULL LEGAL NAME], residing at [GUARANTOR HOME ADDRESS], phone [GUARANTOR PHONE], email [GUARANTOR EMAIL], relationship to Tenant: [RELATIONSHIP];

in favor of [LANDLORD/OWNER NAME] (“Landlord”), regarding the lease dated [LEASE DATE] (the “Lease”) between Landlord and [TENANT NAME(S)] (“Tenant”) for the premises at [PROPERTY ADDRESS, UNIT #, CITY, STATE, ZIP] (the “Premises”). Guarantor acknowledges receiving and reading a complete copy of the Lease.

2. Guaranteed Obligations

In consideration of Landlord entering into (or renewing) the Lease with Tenant — which Guarantor acknowledges as sufficient consideration — Guarantor absolutely and unconditionally guarantees full and timely payment and performance of all of Tenant’s obligations under the Lease, including without limitation:

  1. Rent and any lawful late charges;
  2. Damage to the Premises beyond ordinary wear and tear;
  3. Fees and charges lawfully due under the Lease (utilities billed under the Lease, returned-payment charges, and similar amounts);
  4. Costs of collection and, where permitted by law and the Lease, reasonable attorney’s fees and court costs.

Maximum guaranteed amount, if any: [MAXIMUM DOLLAR CAP OR “NO CAP — FULL GUARANTY”].

3. Joint and Several Liability

Guarantor’s liability is joint and several with Tenant and with any other guarantor. Landlord may proceed directly against Guarantor for any default without first pursuing Tenant, exhausting remedies against Tenant, or applying the security deposit. This is a guaranty of payment and performance, not merely of collection.

4. Duration; Renewals and Modifications

This Guaranty remains in effect for the initial Lease term and for [ALL RENEWALS, EXTENSIONS, AND MONTH-TO-MONTH CONTINUATIONS / THE INITIAL TERM ONLY / RENEWALS THROUGH [END DATE]] (choose one — some states require a guarantor’s fresh consent for renewals or material changes; verify locally). Guarantor agrees that the Lease may be renewed, extended, or modified (including rent adjustments) [WITH / WITHOUT] notice to Guarantor, and that such changes do not release Guarantor, except that a material increase in obligations beyond [DESCRIBE LIMIT, e.g., “10% annual rent growth”] requires Guarantor’s written consent. Guarantor’s obligations for amounts accrued before any termination of this Guaranty survive its termination.

5. Waiver of Notice of Default

To the fullest extent permitted by law, Guarantor waives notice of Tenant’s default, notice of acceptance of this Guaranty, presentment, demand, protest, and notice of nonpayment. Landlord may, but is not obligated to, notify Guarantor of missed payments; failure to notify does not reduce Guarantor’s liability. Some jurisdictions limit enforceability of notice waivers — confirm locally. As a courtesy, Landlord will attempt to copy Guarantor on default-related notices sent to Tenant at the address in Section 1.

6. Credit Check and Financial Information

Guarantor authorizes Landlord and Landlord’s screening provider to obtain consumer credit reports, verify employment and income, and contact references, both for approval of this Guaranty and, as permitted by law, in connection with collection of amounts owed. Guarantor certifies that the financial information provided is true and complete, and has attached the following in support (collectively, Attachment A — Guarantor Financial Information):

  • Completed guarantor application
  • Proof of income (pay stubs / tax return / other: [DESCRIBE])
  • Government-issued ID: [ID TYPE AND NUMBER — REDACT AS APPROPRIATE]
  • Other: [DESCRIBE]

7. General Provisions

This Guaranty binds Guarantor’s heirs, estate, and personal representatives, and benefits Landlord’s successors and assigns. It is governed by the law of [STATE]. If any provision is unenforceable, the remainder stays in effect. This Guaranty, the Lease, and Attachment A are the entire agreement of Landlord and Guarantor; no oral modifications are effective.
