To write a signed statement, put your identity at the top, lay out the facts you personally know in clear chronological order, and close with the specific “under penalty of perjury” language federal law requires before you sign and date it. Done correctly, that document carries the same legal weight as a sworn, notarized affidavit in most federal matters.1Office of the Law Revision Counsel. 28 USC 1746 Unsworn Declarations Under Penalty of Perjury The details below walk through what to include, how to sign it, and what to avoid.
Decide Whether You Need a Declaration or an Affidavit
Before you write a word, work out which format the receiving party expects. A declaration is a written statement you sign “under penalty of perjury” without a notary. Federal law allows declarations to substitute for sworn, notarized documents in nearly all federal proceedings.1Office of the Law Revision Counsel. 28 USC 1746 Unsworn Declarations Under Penalty of Perjury An affidavit is a written statement you sign under oath in front of a notary public, who verifies your identity and seals the document.
Some state courts, real estate transactions, and immigration filings still require affidavits specifically. If the requesting party doesn’t tell you which form they want, a declaration under penalty of perjury is usually enough for federal matters. Ask if you aren’t sure. Submitting a declaration where an affidavit was required gets the document rejected, and you start over.
What to Include
Every signed statement has three layers: who you are, what happened, and the sworn closing. Skip any one of these and the statement is either weakened or inadmissible.
Identification
Open with your full legal name, current address, and contact information such as a phone number or email. Add the date you are writing the statement and, if it matters, the time. Address it to the person or office that will receive it. If you don’t know who that is, “To Whom It May Concern” is acceptable.
The Facts
This is the body of the statement. Describe the events in chronological order, limited to what you personally saw, did, or experienced. Give specific names, dates, times, and locations. If you refer to a document or physical item, describe it clearly enough that a reader can identify it.
The single biggest mistake people make is blending facts with opinions. “I saw the car run the red light at 3:15 p.m.” is a fact. “The driver was being reckless” is a conclusion. Stay with what happened, not what you think about what happened. Speculation, emotional commentary, and guesses at other people’s motives undercut your credibility and give an opposing party something to attack.
The Closing Declaration
Federal law prescribes the exact closing language. If you sign inside the United States, the closing should read substantially as follows: “I declare under penalty of perjury that the foregoing is true and correct. Executed on [date].” If you sign outside the United States, add “under the laws of the United States of America” after “perjury.”1Office of the Law Revision Counsel. 28 USC 1746 Unsworn Declarations Under Penalty of Perjury The U.S. Department of State uses the same formulation for declarations intended for federal court proceedings.2U.S. Department of State. 7 FAM 850 Taking an Affidavit
Don’t paraphrase this language. Courts and agencies look for the specific phrasing, and deviating from it can raise questions about whether the statement qualifies as a valid declaration.
Formatting the Document
Presentation carries more weight than most people expect. A sloppy or disorganized statement gets taken less seriously even when the content is sound. If you’re typing, use a standard font such as 12-point Times New Roman or Arial with one-inch margins and single or 1.5 line spacing. If you’re handwriting, write legibly. A statement nobody can read is a statement nobody will rely on.
Break the narrative into logical paragraphs, each covering a single event or topic. For longer statements, number each paragraph so investigators, attorneys, or officials can reference a specific part in follow-up questions. Keep the tone formal and objective throughout. You are creating a record, not telling a story.
If the events took place in another language or you prefer to write in your native language, the receiving party will usually require a certified English translation that includes a signed statement from the translator affirming completeness and accuracy. Notarization of the translation may also be required.
Signing, Witnesses, and Notarization
Sign at the end of the statement, below the closing declaration. Print your full legal name directly beneath your signature and write the date next to or below it, even if the body of the statement is already dated. If you drafted the statement over several days, the two dates can differ, and having both prevents arguments later about when you finalized it.
Some official processes require a witness. The witness is not vouching for the truth of the content, only confirming that you are the person who signed the document. A witness should sign separately, print their full name, and date their signature.
If you’re preparing an affidavit, you’ll need a notary public. The notary verifies your identity, watches you sign, and affixes an official seal. Do not sign before you are in front of the notary; a notary cannot notarize a signature they didn’t witness. Notary fees vary by jurisdiction but are generally modest, and many banks, shipping stores, and law offices offer the service.
Electronic signatures are legally valid for most federal purposes under the Electronic Signatures in Global and National Commerce Act, which provides that a signature cannot be denied legal effect solely because it is in electronic form.3Office of the Law Revision Counsel. 15 USC 7001 General Rule of Validity The same law allows notarization requirements to be satisfied electronically when the authorized person’s electronic signature is attached to or logically associated with the record. In practice, not every agency or court accepts electronic signatures, and some require wet-ink signatures on paper originals. Confirm the submission requirements before signing electronically, because a rejected filing can mean a missed deadline.
If You Need to Correct a Signed Statement
If you discover an error after signing, do not alter the original. Crossing out text, writing in margins, or whiting out mistakes makes the whole statement look unreliable. Instead, write a separate supplemental statement that identifies the original by date, points to the specific paragraph or fact being corrected, states the correction, and carries its own closing declaration and signature. Submit the supplement alongside the original.
Timing matters. A correction made within days of the original looks like an honest fix. A correction made weeks or months later, especially after other evidence has surfaced, will be scrutinized far more heavily. If you’re already in a legal proceeding, talk to an attorney before filing an amendment, because a retraction that contradicts your earlier statement can create new problems.
What a False Statement Costs
Signing under penalty of perjury is not a formality. Federal perjury is punishable by a fine and up to five years in prison, and the statute reaches any written declaration signed under penalty of perjury, not only courtroom testimony.4Office of the Law Revision Counsel. 18 US Code 1621 – Perjury Generally Separately, submitting a false written statement to any federal agency, even outside a formal legal proceeding, is a federal crime carrying up to five years in prison, with a higher maximum of eight years if the false statement involves terrorism or certain crimes against minors.5Office of the Law Revision Counsel. 18 USC 1001 Statements or Entries Generally
The collateral damage is often worse than the criminal exposure. A false statement sinks whatever claim it was supposed to support. Insurance claims get denied. Employment complaints get dismissed. Immigration applications get rejected permanently.
When You Can Decline
A request for a signed statement is not always an obligation. The Fifth Amendment protects you from being compelled to provide testimony, oral or written, that could incriminate you in a criminal case.6Congress.gov. Fifth Amendment If a truthful account could expose you to criminal liability, you can decline, and you should speak with a lawyer before putting anything on paper. This applies in non-criminal settings as well, including internal employer investigations, insurance company inquiries, and government agency requests. What you cannot do is write a false statement to avoid the problem. That creates far worse exposure under the perjury and false-statement laws above.
Submitting the Statement
Once the statement is complete and properly signed, and witnessed or notarized if required, submit it by whatever method the receiving party accepts: certified mail, email, a secure online portal, or in-person delivery. Keep a copy of the signed original for your records. If you submit electronically, save the confirmation receipt. For in-person delivery, ask for a dated receipt as proof of submission. If there is a filing deadline, build in a buffer. Certified mail takes days, online portals sometimes reject uploads for formatting reasons, and offices close early.
