Project Modification Extension Agreement
What a Project Modification Extension Agreement Is
Why Use a Formal Extension Agreement
A clear, written extension reduces disputes, documents mutual consent to new dates or deliverables, and protects lien, warranty, and payment priorities. Properly executed amendments help enforce revised obligations and create an auditable record for project management, accounting, and compliance purposes.
Who Typically Prepares and Signs One
Project Modification Extension Agreements are used by participants who manage, approve, or fund project changes and schedule extensions.
- Project managers, contract administrators and PMO staff managing scope, schedule, and cost changes.
- General contractors and subcontractors negotiating revised completion dates or phased deliverables.
- Owners, developers, and lenders approving amended milestones, payment schedules, or liquidated damages changes.
Parties should ensure signatory authority is confirmed before execution and retain the signed amendment with the master contract for audit and claims defense.

Frequently Asked Questions About Project Modification Extension Agreements
-
Can I sign the amendment electronically?
Yes. Electronic signatures are generally valid under the federal ESIGN Act (15 U.S.C. ch. 96) and UETA in most states, provided the parties consent to electronic records and the signature method captures intent, attribution, and retainability.
-
When is notarization required?
Notarization is typically required only for instruments affecting title or documents intended for recording; state practices vary, so confirm county recording rules or statutory requirements before assuming a notary is unnecessary.
-
Who must sign on behalf of a company?
A person with express signatory authority—officer, authorized agent, or someone with delegated authority—must sign. Maintain evidence of delegation in corporate minutes or a signed authority letter to avoid disputes.
-
How do I revoke or cancel an amendment?
Revocation requires agreement by all parties or compliance with any termination clause in the amendment; unilateral revocation without contractual basis risks breach claims and should be managed with legal counsel.
-
What if one party refuses to sign?
If a party refuses, revert to the base contract terms or pursue remedies specified in the original agreement; document attempts to negotiate and seek dispute resolution per the contract's dispute clause.
-
How long should I keep the executed amendment?
Retain the signed amendment with the master contract for at least three years after final performance, longer when tax, real estate, or HIPAA rules apply; see IRS (IRC §6501(a)) and HIPAA (45 CFR §164.530(j)).
