What is a Construction Affidavit?

A construction affidavit is a sworn statement made by a party on a building project, confirming facts such as completion of works, payment of subcontractors, or compliance with planning requirements.

GenieAI's template covers all essential sworn declarations.

Frequently Asked Questions

What is a construction affidavit and when is it used in England and Wales?

A construction affidavit is a sworn written statement made by a party connected to a building project, confirming specific facts under oath. It is used in Technology and Construction Court proceedings, adjudications, lien-type claims, and to satisfy lender or insurer requirements on completion of works.

Who can administer the oath for a construction affidavit in England and Wales?

Affidavits must be sworn before a solicitor holding a current practising certificate, a commissioner for oaths, or a court officer authorised to administer oaths under the Oaths Act 1978. The deponent signs in the official's presence and the official endorses the jurat confirming the swearing took place.

What information does a construction affidavit typically cover?

It commonly covers the identity of the parties, the scope and value of works completed, payments received and outstanding, the absence of outstanding claims or defects (where relevant), and compliance with any applicable permits or planning conditions. Lenders use it to confirm a project reached practical completion free of encumbrances.

Is a construction affidavit the same as a statutory declaration in England and Wales?

No. A statutory declaration is made under the Statutory Declarations Act 1835 without an oath, typically for administrative purposes. An affidavit is sworn under oath for use in legal proceedings. Both are signed before an authorised person, but their legal weight and purpose differ in English law.

Can a false construction affidavit lead to criminal liability in England and Wales?

Yes. Making a false statement under oath is perjury under the Perjury Act 1911, carrying up to seven years' imprisonment. Even outside court proceedings, making a false statutory declaration or affidavit for non-judicial purposes can constitute an offence under the same Act or the Fraud Act 2006.

How does a construction affidavit protect a property owner paying for works?

It provides sworn evidence that the contractor has paid all subcontractors and suppliers from earlier payments, reducing the risk of the owner facing unpaid-subcontractor claims. While England and Wales lacks a mechanic's lien system, lenders and purchasers often require an affidavit as contractual protection before releasing final payment.

Do subcontractors need to provide separate affidavits on a construction project?

This depends on the contract terms and the lender's requirements. Where a main contractor is providing a sworn statement, the lender may also require affidavits from major subcontractors confirming their own payment chains are clear. The main contract and any collateral warranties should address this obligation explicitly.

How long should a construction affidavit be retained after practical completion?

Retention for at least 12 years is prudent where the works involve structural elements, aligning with the limitation period for claims under a deed in England and Wales. For non-structural works, six years covers the standard contractual limitation period. Building Safety Act 2022 obligations may require longer retention for higher-risk buildings.

About the Construction Affidavit

A Construction Affidavit is a sworn legal document that allows contractors, subcontractors, and other construction professionals to make verified statements about construction projects under oath. This powerful legal instrument provides documented proof of facts that can be used in payment disputes, lien proceedings, and compliance verification throughout the United States construction industry.

When do you need this document?

You'll need a Construction Affidavit when releasing final payments to ensure all subcontractors and suppliers have been paid, preventing future lien claims against your property. Lenders often require these affidavits before releasing construction loan funds to verify that work has been completed according to specifications. If you're involved in a construction dispute, an affidavit can provide sworn testimony about project timeline, work quality, or payment issues. General contractors use these documents to certify compliance with prevailing wage requirements under the Davis-Bacon Act on federally funded projects. You may also need one when applying for occupancy permits to confirm that all safety standards and building codes have been met.

Key legal considerations

Construction Affidavits carry serious legal consequences since they're sworn under oath and notarized, making false statements a criminal offense that can result in perjury charges. The document must include specific project details, clear identification of all parties involved, and precise statements of fact rather than opinions or assumptions. When used for lien waivers, ensure the affidavit covers all potential claimants including subcontractors, suppliers, and laborers to prevent future payment disputes. The verification section requires your signature acknowledging that the statements are true and complete to the best of your knowledge. Remember that notarization doesn't validate the truthfulness of your statements—it only confirms your identity and willingness to swear to the contents under penalty of perjury.

Legal requirements in United States

Federal construction projects must comply with Davis-Bacon Act prevailing wage requirements, and your Construction Affidavit may need to certify proper wage payments and worker classifications. The Occupational Safety and Health Act requires adherence to construction safety standards, which may be addressed in safety compliance affidavits. State construction lien laws vary significantly across jurisdictions, affecting how affidavits are used in payment and lien waiver processes—some states have specific statutory forms while others allow more flexibility. Most states require Construction Affidavits to be notarized by a licensed notary public, and the notary must verify your identity before administering the oath. State contractor licensing requirements may mandate that only licensed professionals can execute certain types of construction affidavits, particularly those related to substantial completion or code compliance certifications.
