Co Signer Form
Use a Co Signer Form 0 template to make your document workflow more streamlined.
What a co signer form does
A Co Signer Form records a second person’s agreement to share responsibility for a specific transaction, obligation, or contract. The primary signer and co-signer review the same terms, provide identifying information, and sign where required. Its enforceability depends on the underlying agreement, signer authority, consent, accurate execution, and applicable state law. ESIGN and UETA generally recognize electronic records and signatures for covered transactions, but they exclude wills, certain court orders, family law decrees, and other listed records. Confirm notarization, witness, and filing requirements before relying on electronic execution.
Who uses the co signer form
Contracting parties
A landlord, lender, vendor, or contracting party can use the Co Signer Form when a second individual must accept responsibility alongside the primary applicant. Confirm the underlying agreement identifies both parties, explains the co-signer’s obligation, and states any required witness or notary steps.
Business teams
Small businesses, property managers, legal teams, and financial-service providers can route the form to two signers. They should limit access to personal information, preserve consent evidence, and check state law before using electronic execution for a specialized transaction.
How the co signer form works
Prepare the document, assign each signer’s fields, collect both signatures, and preserve the completed record with its audit trail.
Upload form: Upload the Co Signer Form and identify its fillable fields. Assign fields: Review detected fields and assign them to each signer. Send signers: Send the form to the primary signer and co-signer. Store record: Collect signatures and retain the completed audit trail.

Co signer form challenges
Identifying the exact obligation can prevent a co-signer from accepting terms broader than the intended transaction. Unassigned signature fields can leave the primary signer or co-signer without evidence of personal assent. Missing witness or notary steps can affect enforceability when state law requires additional execution formalities. Sending the completed form to the wrong recipient can expose financial and personally identifying information.
Legal standing and business value
A properly completed Co Signer Form creates a reproducible record of consent, signer identity, and agreed obligations. ESIGN, 15 U.S.C. ch. 96, and UETA generally support electronic signatures for covered transactions when intent, consent, attribution, and record reproduction are established. Wills, codicils, testamentary trusts, certain court orders, and family law decrees remain excluded.

Co signer form use cases
Organizations use co-signer workflows when one party needs a second signer’s documented agreement to the same obligation.

Co signer form troubleshooting
Resolve field assignment, signer identity, plan, legal-validity, and regulated-data questions before relying on a completed Co Signer Form.
On the Business plan, upload the Co Signer Form, review detected fields, assign each signer, and send separate invitations. If the fields are not detected correctly, place signature, date, and required-text fields manually before sending.
signNow supports legally binding eSignatures and audit trails on the Business plan. For a U.S. transaction, preserve intent, consent, signer attribution, and a reproducible record under ESIGN and applicable state UETA or New York ESRA requirements.
Use signNow’s SMS verification or stronger signer authentication where identity risk justifies it. If the transaction requires notarization, electronic signing alone does not replace the applicable state notary procedure or required audio-video and journal controls.
The Business plan is listed at $8/user/month with annual billing and includes legally binding eSignatures, templates, mobile apps, audit trails, ISO 27001, SOC 2, and GDPR coverage. Month-to-month pricing is higher at $20/user/month.
Business Premium is listed at $15/user/month with annual billing and adds bulk send, kiosk mode, request payments, and quick invite links. Those features help only when the same Co Signer Form must be sent repeatedly or signed in person.
For health-care workflows involving protected health information, signNow identifies HIPAA compliance as requiring a business associate agreement. Confirm the document’s PHI scope, execute the BAA, and apply the organization’s retention and access policies.
