How To Write An Addendum To A Lease With Addendums Form
Use a How To Write An Addendum To A Lease with Sample Addendums template to make your document workflow more streamlined.
What a lease addendum form does
A lease addendum is a written amendment that changes identified terms of an existing rental agreement without replacing the entire lease. The parties name the original lease, state the revised provision, identify the effective date, and sign their approval. For this form, the practical task is linking the new language to the original agreement, avoiding contradictions, and preserving each party’s completed copy. signNow supports the workflow by letting you upload the addendum, place fields, send it for signature, and retain an audit trail.
Who uses a lease addendum form
Landlords
Property owners and landlords use an addendum to document approved changes to rent, occupants, pets, repairs, utilities, or renewal terms without rewriting the entire lease.
Property managers
Property managers and tenants use the signed addendum to confirm negotiated changes, preserve each party’s copy, and maintain a clear record alongside the original lease.
How the lease addendum workflow works
A lease addendum moves from document preparation to assigned signatures, completion, and organized storage without replacing the original lease.
Upload document: Upload the lease addendum and identify its fillable fields. Prepare fields: Review detected fields and add missing signer or date fields. Set recipients: Assign landlord and tenant signing order before sending. Archive record: Store the completed addendum with its audit trail.

Assign landlord and tenant fields directly so each party signs the intended provisions in the correct order.
Reusable templates
Use reusable fields for rent, occupants, pets, utilities, renewal dates, or repair obligations across recurring lease amendments.
Audit evidence
Capture signing events and document history to support later review of when each party approved the addendum.
Remote delivery
Send the completed addendum through email or a signing link when parties are not meeting in person.
Organized records
Keep the signed addendum with the original lease so property records show the full agreement history.

Legal standing of a signed lease addendum
A lease addendum can provide admissible evidence when the parties show intent, consent, attribution, and reliable record retention. ESIGN and applicable state law, including UETA or New York ESRA, generally recognize electronic signatures, while wills, court orders, and family-law decrees remain excluded.

Lease addendum troubleshooting questions
Resolve field, signer, legal-validity, notarization, plan, and recordkeeping questions before relying on a completed lease addendum.
Upload the addendum as a supported PDF or document file, then inspect every auto-detected field. Add missing landlord, tenant, date, and initials fields manually before sending the document.
The Business plan includes legally binding eSignatures, templates, audit trails, and mobile apps. If the workflow requires bulk send, Business Premium adds that capability for recurring addenda.
ESIGN and UETA recognize electronic signatures when intent, consent, attribution, and record retention are established. For consumer-facing transactions, review the electronic-record disclosure requirements in 15 U.S.C. §7001(c).
Use signNow’s signer assignment and signing order to distinguish landlord and tenant responsibilities. Review the completed PDF and audit trail before treating the amendment as part of the lease record.
A signature does not replace a state-required notarization, witness process, or recording requirement. Check the property’s state law and county procedure before using an electronic addendum for a deed-related change.
Export the completed addendum and audit trail, then retain them with the original lease under the applicable state, housing, tax, or business-record policy. Federal retention periods do not automatically govern every lease.
