Construction Document Notarization Guide

Construction projects involve a significant volume of legal and financial paperwork, and many of those documents require notarization at various stages of the project. Remote online notarization (RON) allows eligible contractors, subcontractors, property owners, and construction professionals to have qualifying documents notarized through a secure live video session — without visiting a notary's physical office.

Whether you are a general contractor managing a commercial project, a subcontractor preparing payment documents, a property owner recording a notice of commencement, or a permit expediter handling building department forms, remote online notarization may offer a faster and more flexible option for eligible documents.

This guide covers the types of construction documents that may require notarization, how the online notarization process works for construction-related documents, and what you should confirm with your receiving party before scheduling a session. iRemoteNotary is not a law firm and does not provide legal advice — always consult your attorney, title company, lender, or appropriate professional for guidance specific to your project.

Many documents generated during the life of a construction project may require notarization. The specific requirements depend on the document type, the receiving party (such as a county recorder, title company, lender, or project owner), the state or jurisdiction, and the terms of the construction contract.

Notices of commencement are among the most commonly notarized construction documents. In Florida and other states, a notice of commencement filed with the county recorder must be notarized before recording. Remote online notarization may be accepted by the county recorder, but confirm acceptance before scheduling.

Contractor affidavits and final payment affidavits are sworn statements used to confirm that all subcontractors, suppliers, and laborers have been paid before a final draw or project closeout. These documents typically require notarization, and eligible affidavits can often be notarized online.

Lien waivers, lien releases, and partial and final releases of lien may require notarization depending on state law, the contract terms, and the receiving party. Some conditional and unconditional lien waivers are notarized before payment is released; others after. Always confirm the specific requirements with your contractor, lender, or title company.

Payment applications such as the AIA G702 may include certifications or sworn statements that require notarization. Confirm with the project owner, lender, or contract administrator whether notarization is required and what form is acceptable.

Owner-builder affidavits, permit authorization forms, change of contractor affidavits, and other building department documents may also require notarization depending on the jurisdiction. Always verify with the issuing or receiving agency.

The process for notarizing a construction document online follows the same steps as any remote online notarization session. First, submit your request and upload your unsigned document. Second, complete identity verification as required for the session. Third, connect with a commissioned remote online notary through a secure audio-video call, sign the document electronically, and receive the notarized document digitally after the session.

It is critical that you do not sign the document before the notary session. The notary must witness your signature during the live session for the notarization to be valid.

Construction documents often have specific requirements around the notarial certificate, signature blocks, and wording. Make sure your document is in its final form before the session. If you are unsure about the correct form, consult with your attorney, contractor, title company, or the receiving party before uploading.

Acceptance of remote online notarization for construction documents varies significantly. Some county recorders, building departments, title companies, and lenders readily accept electronically notarized construction documents; others still require paper and in-person notarization. Confirm acceptance before every session.

General contractors managing large commercial or residential projects benefit from the speed and convenience of remote notarization, particularly for project closeout documents and final payment affidavits that may require quick turnaround.

Subcontractors and material suppliers who need to notarize lien waivers or payment affidavits before receiving payment can use remote online notarization to complete the process without leaving their job site or office.

Property owners who need to sign and notarize an owner-builder affidavit, a permit authorization form, or a notice of commencement may find remote notarization more convenient than scheduling an in-person appointment.

Permit expediters handling multiple building department submissions can use remote notarization for owners and contractors who need affidavits or authorization forms notarized quickly.

Real estate investors and developers managing multiple projects can streamline notarization workflows across project teams, reducing delays in payment cycles and title clearance.

Construction documents can involve significant legal and financial consequences. Lien rights, payment obligations, and recording deadlines are governed by state-specific laws that can be strict and time-sensitive. A lien waiver signed incorrectly, for example, may inadvertently waive rights before payment is received. A notice of commencement with incorrect notarization may not be accepted for recording.

Remote online notarization handles the notarization component, but it does not address the substantive legal requirements of the document itself. iRemoteNotary does not prepare, review, or advise on construction documents. Always obtain your forms from the correct source — your attorney, project owner, title company, lender, or the applicable government office — and confirm the exact requirements before the session.

Acceptance of remote online notarization by county recorders, building departments, and other government agencies varies by jurisdiction. Before scheduling any session for a construction document, confirm in writing with the receiving party that they accept electronically notarized documents.

To use iRemoteNotary for construction document notarization, start by identifying the document you need notarized and confirming the format, wording, and notarization requirements with the receiving party. Obtain the correct, final version of your unsigned document.

Submit your request through the iRemoteNotary platform, noting the type of construction document in the request notes. Upload your unsigned document before the session. Have your valid government-issued photo ID ready. Ensure your device has a working camera and microphone and that you have a stable internet connection for the session.

If your document requires witnesses — as some lien waivers or notices of commencement might — confirm witness requirements and arrange for any required witnesses before the session. After the session, distribute the notarized document to the appropriate parties and retain a copy for your project records.
