A business affidavit is a written statement in which someone authorized to speak for a company swears, under penalty of perjury, that specified facts are true. Companies use them to authenticate records for court, confirm that an officer has authority to sign a deal, verify ownership during acquisitions, replace lost stock certificates, and satisfy regulatory certifications. What separates an affidavit from an ordinary company letter is personal legal exposure: the signer (the affiant) takes on the same liability a witness would face for lying on the stand, and federal perjury alone carries up to five years in prison.1Office of the Law Revision Counsel. 18 USC 1621 – Perjury Generally
When a Company Needs One
Getting Business Records Into Evidence
The most routine use is the affidavit of business records. Federal Rule of Evidence 803(6) treats business records as an exception to the hearsay rule when the record was made near the time of the event by someone with knowledge and kept as part of the organization’s regular activities.2Cornell Law Institute. Federal Rules of Evidence Rule 803 – Exceptions to the Rule Against Hearsay Rule 902(11) lets the custodian establish those foundational facts through a written certification rather than live testimony, provided the opposing party gets reasonable notice and a chance to inspect the records.3Cornell Law Institute. Federal Rules of Evidence Rule 902 – Evidence That Is Self-Authenticating That is what allows invoices, ledgers, and emails to come in at trial without pulling a records clerk into the courtroom for each one.
Loans and Corporate Authority
Lenders regularly ask for affidavits during commercial underwriting. A borrowing entity may need an officer to swear that the company is authorized to take on the debt, that submitted financial statements are accurate, or that no undisclosed liens sit against collateral. The same document also confirms that the person about to sign a high-value contract or lease actually has the authority to bind the company, so the deal cannot unravel later over a dispute about signing power.
Lost Stock Certificates
When a shareholder loses a stock certificate, the issuing company almost always requires a sworn statement before it will issue a replacement. The SEC notes that the owner must state all the facts surrounding the loss in an affidavit as part of the replacement process.4Investor.gov. Lost or Stolen Stock Certificates The sworn certification protects the company against a later claim that the original certificate was in fact transferred to someone else.
Mergers, Acquisitions, and Bulk Sales
Deals involving mergers, acquisitions, and asset purchases routinely rely on affidavits to verify ownership and confirm the absence of undisclosed liabilities. A seller may swear that no pending lawsuits exist against the company, or that a specific asset is owned free and clear. In bulk asset sales, the Uniform Commercial Code’s bulk sales provisions call for the seller to provide a verified list of creditors so the buyer is not blindsided by debts attached to the assets. Skipping that protection can let creditors challenge the sale.
Federal Contracting
Companies pursuing federal contracts often submit sworn certifications about size and socioeconomic status. The Small Business Administration requires self-certification of small business status, and those certifications can be challenged through a formal protest process that demands specific written evidence supporting or contesting the claim.5U.S. Small Business Administration. Handling Protests A false size certification can trigger False Claims Act liability on top of losing the contract.
What the Document Must Contain
The structure is consistent across purposes. Getting each element right on the first draft matters, because corrections after notarization mean starting over.
- Affiant identification. The full legal name and title of the person signing, establishing that the affiant has the knowledge and authority to make the claims. A warehouse manager can swear to inventory records; a CFO can attest to financial data.
- Entity identification. The legal name of the business exactly as it appears in state registration filings, including designators like “LLC” or “Inc.,” along with the principal business address.
- Competency statement. A declaration that the affiant is of sound mind, competent to testify, and personally acquainted with the facts. Courts will reject documents that omit it.
- Factual assertions. The core of the affidavit. Each statement should be specific — dates, dollar amounts, serial numbers, descriptions of events — and should indicate whether the fact comes from personal knowledge or from review of business records. Vague language invites challenges.
- Perjury acknowledgment. An explicit statement that the affiant understands the consequences of false information. In federal matters, the closing must substantially follow 28 U.S.C. § 1746: “I declare under penalty of perjury that the foregoing is true and correct.”6Office of the Law Revision Counsel. 28 USC 1746 – Unsworn Declarations Under Penalty of Perjury
- Signature and date. Written in first person, signed by the affiant, and dated.
Templates for common affidavit types are available through court clerks’ offices, banking portals, and industry-specific regulatory agencies. Using one designed for the specific purpose reduces the risk of omitting a required element.
How to Execute It
Most business affidavits require notarization to be legally effective. The affiant signs in the physical presence of a commissioned notary public. The notary verifies identity using a current government-issued ID, administers an oath or affirmation, and applies an official seal along with the commission expiration date. The seal is what confirms that a government-authorized officer verified the signer and witnessed the signature.
Notary fees vary by jurisdiction. Most states set statutory maximums for standard notarial acts, and for a straightforward acknowledgment or oath the fee typically falls between $2 and $25. Remote or electronic notarizations sometimes carry higher maximum fees than in-person services.
Once notarized, the affidavit goes to whoever requested it: a court, lender, agency, or counterparty in a transaction. Some recipients accept electronic filing; others require a physical original. When paper is needed, certified mail or another trackable method creates a delivery record in case receipt is later disputed.
Skipping the Notary in Federal Matters
For federal matters, a notary may not be necessary. Under 28 U.S.C. § 1746, any document that federal law requires to be supported by a sworn statement can instead be supported by an unsworn written declaration signed under penalty of perjury.6Office of the Law Revision Counsel. 28 USC 1746 – Unsworn Declarations Under Penalty of Perjury The declaration carries the same legal force as a notarized affidavit if it includes the prescribed closing language, the signer’s date, and the signature. It does not cover depositions, oaths of office, or situations where a specific official other than a notary is required, and it applies only to federal proceedings. State courts and agencies may still demand a notary.
Remote Online Notarization
Remote online notarization (RON) lets the affiant appear before a notary through audio-video technology. As of 2025, 47 states and the District of Columbia have enacted laws permitting it, though procedures and technology requirements vary. The SECURE Notarization Act, which would set uniform national standards for remote and electronic notarization, has been introduced in Congress but remains at the committee stage.7Congress.gov. S.1561 – SECURE Notarization Act of 2025 Until then, check state-specific RON rules: some require the notary to be commissioned in the same state, while others recognize out-of-state remote notarizations.
Fixing a Mistake After Signing
Errors caught after notarization cannot be corrected on the existing document. White-out, cross-outs, and interlineations void a notarized affidavit. The standard fix is to draft a new affidavit with the corrected information and go through the full signing and notarization process again. If the original was already filed with a court or agency, the corrected version usually needs to be filed as a supplemental affidavit, with notice to the receiving party.
That is why the details need to be right before the notary appointment. Double-check names, dates, dollar amounts, and entity designators against official records before signing. A $15 notary fee becomes a $30 problem when the process has to be repeated, and in litigation a corrected affidavit gives opposing counsel an easy angle on credibility.
Penalties for a False Statement
The consequences of lying in a business affidavit are serious, and they can hit both the individual signer and the company.
Criminal Perjury
Under federal law, anyone who willfully states something they do not believe to be true in a sworn affidavit or in a declaration under penalty of perjury faces up to five years in federal prison, a fine, or both.1Office of the Law Revision Counsel. 18 USC 1621 – Perjury Generally The federal statute expressly covers both traditional sworn statements and unsworn declarations under 28 U.S.C. § 1746, so skipping the notary does not reduce criminal exposure. Every state also has its own perjury statute, and most treat it as a felony.
Civil Liability and the False Claims Act
When a false affidavit is used in connection with a government contract or payment, the federal False Claims Act adds a separate layer of liability. A person who knowingly submits a false record or statement material to a fraudulent claim against the government faces treble damages plus a per-claim civil penalty.8Office of the Law Revision Counsel. 31 US Code 3729 – False Claims Those per-claim penalties are adjusted annually for inflation and currently range from $14,308 to $28,619 per violation.9Federal Register.
