Month To Month Addendum Form
Use a Month To Month Addendum 0 template to make your document workflow more streamlined.
What a month-to-month addendum does
A Month To Month Addendum Form records specific changes to an ongoing lease or business agreement without replacing the original document. It can identify the parties, property or account, effective date, rent or fees, notice rules, occupants, services, and other amended terms. The parties review those changes, sign the addendum, and keep it with the original agreement. In the United States, electronic execution may be supported by ESIGN and applicable state law, but landlord-tenant requirements and exclusions vary by state.
Who benefits from month-to-month addenda
The form is most useful when parties need to change continuing terms without replacing the complete underlying agreement.
Independent landlords use a month-to-month addendum to document rent changes, notice periods, occupants, or property rules without recreating the entire lease. They can send the revised terms electronically and retain the signed record with the original agreement for later reference. Property management companies use reusable templates and controlled signer routing for recurring lease amendments across portfolios. Centralized administrators can standardize required fields while authorized leasing staff send property-specific addenda to tenants and co-signers. Enterprise housing operators use role-based workflows to separate template ownership, sending authority, and record access. A shared signNow process helps coordinate amendments across regional teams while preserving each executed addendum and its audit trail.
These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.
Who uses a month-to-month addendum
Real estate
Landlords and property managers use the addendum to record rent, notice, occupancy, maintenance, or other continuing lease terms. Tenants and co-signers review the exact changes, sign electronically when permitted, and receive a completed copy linked to the original agreement.
Business contracts
Businesses and service providers use a month-to-month addendum when the commercial relationship continues but specific pricing, scope, access, or notice terms change. Authorized representatives can sign without circulating a fully redrafted agreement.

Enterprise deployments may also require API access, SSO provisioning, managed-device policies, and configuration aligned with internal retention and security controls.
Best practices for a month-to-month addendum
Accurate cross-references, clear signer assignments, and controlled records reduce disputes over changing month-to-month terms.
Identify every changed term
Match the underlying agreement
Assign fields to the right signer
Preserve the executed record
Privacy and disclosure issues to prevent
Including a tenant’s Social Security number, bank details, or other unnecessary personal data exposes information beyond what the addendum requires. Failing to capture electronic consent or provide required consumer disclosures can weaken evidence that the signer agreed to electronic records. Granting every leasing employee access to all properties can expose tenant information and violate internal access-control policies. Sending the addendum to an outdated email address can leave the intended tenant or authorized representative without attributable notice.
Risks of an incomplete addendum
Signer intent
Contract ambiguity
No audit trail
Timing dispute
Legal standing of the addendum
A month-to-month addendum can be admissible when the parties show intent, consent to electronic records, signer attribution, and reliable retention and reproduction. ESIGN, 15 U.S.C. ch. 96, and applicable state law such as UETA support electronic contracts, but exclude wills, codicils, testamentary trusts, court orders, and specified family-law documents.

Month-to-month addendum examples by industry
These examples show how documented signNow customer experience can inform recurring addendum workflows across regulated and contract-based operations.
Real estate
Martin Properties can use a month-to-month addendum workflow to update rental terms without arranging an in-person meeting.
- Update rent, dates, or notice terms
- Route the addendum to each signer
Martin Properties founder Tim Martin reports processing and executing documents online with compliance and security, including mobile and offline work. That documented experience provides a relevant model for property teams handling recurring lease amendments, while the specific addendum terms remain subject to the applicable state landlord-tenant law.
Healthcare
A healthcare practice can use a month-to-month addendum to document changing service or occupancy terms while limiting access to authorized staff.
- Collect signatures on revised terms
- Retain the completed record securely
Fertility Centers of Illinois founder John Butler cites signNow’s responsive team and effective API in the organization’s experience. A healthcare organization applying that workflow to this addendum should also confirm its HIPAA obligations and execute a business associate agreement where required.
Troubleshooting a month-to-month addendum
These answers address field setup, electronic-signature validity, state-law limits, privacy, and signNow plan constraints for this addendum workflow.
Upload the signed PDF and review every detected field before sending. Correct field types, signer assignments, and required status in the editor; auto-detection does not replace a page-by-page check of the addendum’s rent, dates, and notice terms.
Use signNow’s Business plan for legally binding eSignatures, templates, audit trails, and mobile apps at $8/user/month with annual billing. Business Premium is $15/user/month and adds bulk send, which matters when sending the same addendum structure repeatedly.
ESIGN and UETA support electronic signatures when intent, consent, attribution, and record retention requirements are met. For a consumer-facing lease workflow, provide the electronic-record disclosure and confirm access requirements under 15 U.S.C. §7001(c).
A signed addendum does not replace state landlord-tenant rules. Check the property’s state requirements for rent increases, notice periods, disclosures, and delivery methods before sending; signNow provides the signing workflow, not the governing lease-law analysis.
For health information included in an addendum workflow, signNow identifies HIPAA compliance as requiring a business associate agreement. Limit fields to necessary information and confirm the covered entity’s privacy and retention policies before sending.
Business subscription plans include 100 signature invites per user per year, with overage fees; Site License pricing is $1.50 per signature invite. Choose the plan based on projected addendum volume rather than assuming unlimited subscription usage.
