Co Signer Agreement Form
Use a Co Signer Agreement Form template to make your document workflow more streamlined.
What a co-signer agreement does
A Co Signer Agreement Form records a second person’s promise to support another party’s contractual, rental, loan, or payment obligation. It identifies the primary signer, co-signer, covered obligation, payment or performance terms, dates, and signatures. In signNow, you upload the form, review automatically detected fields, assign each field to the correct signer, and send it for completion. ESIGN and applicable state electronic-transaction law can support enforceability when intent, consent, attribution, and record reproduction are established. State contract and guaranty rules still control the underlying obligation.
Who uses a co-signer agreement
Property and lending teams
Landlords, lenders, and property managers use the form to document a second party’s promise alongside a lease, loan, or rental obligation. The agreement should identify each signer, define the co-signer’s obligations, and preserve the completed record for later enforcement or account review.
Business operators
Small businesses and service providers use the form when a customer needs another individual to guarantee payment or performance. Contracts, invoices, and consent-related agreements should identify the primary party, co-signer, covered obligation, and signature sequence clearly.

Avoid co-signer agreement mistakes
The form names a co-signer but does not define which payment, lease, loan, or performance obligation that person guarantees. The primary signer and co-signer receive interchangeable fields, weakening attribution of each person’s separate promise. The completed agreement lacks a connected audit trail, making signer identity and signing sequence harder to establish during a dispute. The agreement is stored without its completion certificate, signature dates, or governing transaction reference.

Troubleshoot co-signer agreements
Resolve field, signer, consent, plan, and record-retention issues before relying on a completed Co Signer Agreement Form.
Upload the agreement as a readable PDF, then review signNow’s detected fields before sending. If a signature or date field is missing, add it manually and assign it to the correct signer rather than relying on automatic placement.
Use signNow’s signer-role assignment to distinguish the primary party from the co-signer. Confirm each person’s email address and signing order before sending, because an incorrect role can attach a signature to the wrong contractual obligation.
Business includes legally binding eSignatures and audit trails at $8/user/month when billed annually. Business Premium costs $15/user/month annually and adds bulk send, while Enterprise costs $30/user/month annually and adds advanced signer authentication.
For a consumer-facing transaction, provide the ESIGN Act disclosure explaining paper-record rights, electronic access, and consent withdrawal procedures. The disclosure requirement comes from 15 U.S.C. §7001(c), not from the signNow audit trail.
signNow supports ESIGN and UETA-compliant electronic signatures, but those statutes exclude wills, codicils, testamentary trusts, court orders, and specified family-law documents. Confirm that the co-signer agreement concerns an eligible business transaction.
Export the completed agreement and audit trail from signNow, then store both under the retention rule governing the transaction. Federal periods differ by record type; for example, IRS tax records generally use IRC §6501(a), not a universal co-signer deadline.
