This guarantee is a continuing, absolute, and primary obligation and is independent of any security or other remedy held by the Landlord.

The Co-Signer agrees that the Landlord may, at the Landlord's election and without prior notice to or consent from the Co-Signer, (a) extend, modify, or waive any provision of the Lease with the Tenant, (b) accept partial payments, (c) release or substitute any security, and (d) proceed against any party or security without first proceeding against the Co-Signer. The Co-Signer waives any right to require the Landlord to proceed against the Tenant, to pursue any other remedy, or to enforce any security prior to enforcing this Guarantee.

Term; Scope; Liability

This Guarantee shall remain in full force and effect through the entire Term of the Lease and any extensions, renewals, holdovers, or periods during which Tenant or any successor remains liable for the Obligations, and until all Obligations have been satisfied in full.

Financial Terms

Covenants; Remedies

Upon Tenant's default under the Lease, the Landlord may pursue any remedy available at law or in equity, including termination of the Lease, acceleration of sums due, and recovery of damages. The Co-Signer shall be liable for all such sums and shall pay all reasonable costs of collection, including attorneys' fees, whether such costs are incurred before or after judgment.

The Co-Signer expressly waives any right to require the Landlord to exhaust remedies against Tenant, to pursue remedies against other guarantors or security, or to give notice of acceptance of this Guarantee. The Co-Signer further waives any defense based on any disability, lack of capacity, or bankruptcy of the Tenant.

Representations and Acknowledgements

The Co-Signer represents and warrants that the information provided in this Agreement is true and complete and that the Co-Signer has the authority to enter into this Agreement.

Governing Law; Venue

This Agreement shall be governed by and construed in accordance with the laws of the state in which the Property is located. The parties submit to the exclusive jurisdiction of the state and federal courts located in that state for resolution of any disputes.

What a Real Estate Co-Signer Agreement Is and When it Applies

A Real Estate Co-Signer Agreement is a legally binding contract in which an individual (the co-signer or guarantor) accepts responsibility for another party's obligations under a lease, mortgage, or other real estate obligation if that primary party defaults. It identifies the parties, describes the underlying obligation, sets the scope of the guarantee (limited or unlimited), states the term and events of default, and specifies remedies such as payment, eviction cooperation, or enforcement actions. The agreement should clearly record consideration, signatures, and any required notarization or witness acknowledgments to maximize enforceability.

Why Use a Co-Signer Agreement for Real Estate Transactions

A clear co-signer agreement reduces ambiguity about financial responsibility, protects property owners and lenders, documents the co-signer's consent to be liable, and improves underwriting decisions by providing written evidence useful for enforcement and credit reporting.

Why Use a Co-Signer Agreement for Real Estate Transactions

Typical Parties and Professionals Involved

Stakeholders typically include the primary obligor, the co-signer, the property owner or lender, and often an attorney, title officer, or property manager who reviews or stores the executed agreement.

  • Landlords and property managers who require added credit support for tenants with limited or poor credit histories.
  • Lenders and mortgage servicers that seek an additional signature to secure loan repayment obligations.
  • Borrowers, tenants, and family members acting as guarantors to enable tenancy or financing when the primary applicant does not qualify.

Core Sections You Should Include in a Professional Agreement

A robust Real Estate Co-Signer Agreement organizes obligations, limits, and enforcement mechanisms so all parties understand risk and remedies.

Parties and Recitals

Identify each party by full legal name, entity type, and role; state the underlying contract (lease, promissory note, mortgage) and the factual basis for the guarantee.

Guarantee Language

Specify whether the co-signer guarantees payment only, performance, or both; include whether the obligation is primary, secondary, joint and several, or limited to a dollar cap.

Term and Scope

Describe the guarantee duration, whether it survives assignment or sale, and conditions that terminate the co-signer’s continuing obligation.

Default and Remedies

Set out events constituting default, notice procedures, cure periods, late fees, and the co-signer’s obligations to pay, defend, or cooperate in remedies such as eviction or foreclosure.

Consideration and Covenants

Record the consideration received by the co-signer (e.g., permission to execute, loan proceeds) and include affirmative and negative covenants that affect continued liability.

Execution, Notary and Acknowledgment

Include signature blocks with dates, printed names, notary acknowledgements or witness lines where state law or lender policy requires them, and space for initials on each page.

Step-by-Step: Completing a Co-Signer Agreement

Follow these steps to create, verify, and finalize a valid co-signer agreement suitable for leasing or lending.

  • 01
    Draft Terms: Prepare the agreement with clear guarantee language and defined remedies.
  • 02
    Verify Identity: Confirm each signer’s identity using government ID and, if using e-signature, an authentication method.
  • 03
    Sign and Notarize: Obtain signatures and notarization or witnesses if required under state or lender rules.
  • 04
    Distribute Copies: Provide countersigned copies to all parties and retain originals in your records.

Common Digital Workflow Settings for Online Completion

Configure your e-signature workflow to match legal and operational requirements before sending the agreement to signers.

Field Configuration
Authentication Email link plus optional SMS code for signer verification
Signature Type Choose electronic signature (audit trail) or require wet signature if policy requires
Notarization Enable Remote Online Notarization where state law and parties permit
Routing Order Set signer sequence: primary obligor then co-signer then property owner

Digital Delivery, Integrations, and File Formats

Ensure the chosen platform provides a complete audit trail, secure storage, and any compliance features your industry requires, such as a HIPAA BAA if protected health information is included.

  • Integrations: Connectors for Salesforce, NetSuite, Google Workspace, Box and others
  • Document Formats: PDF and DOCX support, maintain a tamper-evident signed PDF
  • Authentication: Email, SMS, KBA or advanced signer authentication available

Where to Send or File the Executed Agreement

After execution, deliver signed copies to the parties and retain records where they are accessible for enforcement and audits.

  • Property Owner: Provide the landlord or property manager with a countersigned copy
  • Lender or Servicer: Deliver to the lender when the guarantee is collateral for a loan
  • Title or Closing Agent: If required, submit to title company for closing or recording
  • Document Retention: Store a copy in tenant or loan file for the required retention period

Key Timing Considerations and Common Deadlines

Track timing for execution, delivery, and any required notarization to avoid enforceability or operational delays.

Execution Before Effectiveness:

Obtain signatures before the lease start date or loan funding to ensure enforceability

Countersigned Copy Delivery:

Provide a countersigned copy to each party within five business days of final signature

Notarization Timeline:

Notarize before recording or where state law requires notarization for certain acknowledgments

Recording Deadlines:

If mortgage-related, coordinate recording to match lender conditions for funding

Retention Start Date:

Retention typically begins on the effective date or closing date of the transaction

Common Errors to Avoid When Preparing Co-Signer Agreements

  • Using informal or ambiguous guarantee language that does not state whether obligations are primary or secondary and how enforcement proceeds.
  • Failing to verify the co-signer’s identity or using inconsistent names between ID and the agreement, which can complicate enforcement or credit checks.
  • Neglecting required notarization or witness lines where state law or lender policy demands them, leading to potential challenges in court.
  • Overlooking notice and cure provisions so parties lack agreed procedures for default notices, dispute resolution, or debt collection steps.

Legal and Financial Risks If the Agreement Is Incorrect

Personal Liability: Co-signer may be legally obligated to pay outstanding amounts
Credit Impact: Defaults can affect the co-signer’s credit report and score
Enforcement Costs: Attorneys’ fees and collection costs may be recoverable under the contract
Invalid Execution: Improperly executed agreements risk being unenforceable
Fraud Exposure: Insufficient identity checks increase fraud and repudiation risk
Tax Consequences: Gifts or transfers tied to guarantees can have tax reporting effects

Practical Examples of Co-Signer Agreement Uses

Real-world scenarios show how co-signer agreements enable transactions that otherwise could not proceed.

Martin Properties — Lease Guarantees

A regional property manager used co-signer agreements to approve tenants with limited credit

  • Reduced in-person signings and travel
  • "I can process and execute all of these documents online with 100% compliance and built-in security. Whether on mobile or working offline, I can get forms back to their necessary parties efficiently."

Optica Ventures — Small Portfolio Lender

A small investor required cosigners on short-term bridge loans

  • Secured faster underwriting approval
  • "The interface is simple and easy-to-use for our team; more importantly, it is just as easy for our customers."

Practical Tips for Accurate, Enforceable Agreements

Follow these best practices to reduce disputes, expedite processing, and improve enforceability across jurisdictions.

Use Precise Names
Always use the co-signer’s full legal name and include any trade or DBA names; verify names against government ID or corporate registration to avoid mismatch disputes during enforcement.
Define Scope Clearly
State exactly what obligations the co-signer guarantees, whether liability is joint and several, and whether obligations include attorneys’ fees and collection costs to avoid later interpretation disputes.
Verify Identity and Consent
Confirm identity with government ID, use clear ESIGN disclosures for consumer transactions, and document consent to electronic records and signatures where applicable to meet the four-part ESIGN test.
Document Notices and Cure
Include notice addresses, cure periods, and escalation steps so parties have agreed procedures before remedies are sought, which often speeds resolution and reduces litigation risk.
