To make a sworn statement, write a first-person account of facts you personally witnessed, close it with a declaration under penalty of perjury, and either sign it before a notary or, for many federal matters, sign it yourself as an unsworn declaration. The document’s legal force comes from that penalty: under federal law, a material falsehood in a sworn statement is perjury, punishable by a fine, up to five years in prison, or both.1Office of the Law Revision Counsel. 18 USC 1621 – Perjury Generally
What Makes a Statement Sworn
Two elements turn a written account into a sworn statement. You take an oath or affirmation, verbally confirming the contents are true, and you sign knowing that lying exposes you to perjury charges. An oath invokes a religious or spiritual pledge; an affirmation is the secular equivalent and carries the same legal force. Either satisfies the requirement, and no one can compel you to choose one over the other.
“Material” in the perjury statute means the false information could influence the outcome of the matter. The penalty applies whether the document was signed inside or outside the United States.
Gather Your Information First
Before drafting, get clear on two things: what the statement is for and what you personally know. Sworn statements appear in court filings, insurance claims, immigration applications, military investigations, and business disputes, and the purpose shapes what facts matter.
Pull together the specifics you plan to include: dates, times, locations, and the names of anyone involved. Collect supporting documents such as emails, photographs, contracts, police reports, or medical records. You usually won’t attach these to the statement, but having them in front of you while writing prevents vague, approximate language that makes a statement look unreliable. Organize the facts chronologically so the narrative reads cleanly.
Drafting the Statement
Write in the first person throughout. Every sentence should reflect what you saw, did, or experienced. Courts expect sworn statements to rest on personal knowledge, not secondhand information or speculation.2Legal Information Institute (LII) / Cornell Law School. Federal Rules of Evidence Rule 602 – Need for Personal Knowledge If you didn’t witness something directly, leave it out. This is where most people weaken their own statements by including things they heard from someone or believe must have happened. A reader will discount those passages and may question the rest.
Opening and Identification
Head the document “Sworn Statement” or “Affidavit.” In the first paragraph, identify yourself by full legal name, address, and date of birth, then state the purpose in a sentence or two: “I, [Name], make this sworn statement in connection with [describe the matter].” Some agencies and courts have their own required formats, so check before drafting from scratch.
Body
Present the facts in numbered paragraphs, one event or point per paragraph. The numbering isn’t decorative; it lets attorneys and judges cite specific portions without confusion. Stick to what happened, when, and where. Keep opinions out unless the requesting party asked for them and you label them clearly. When you need to estimate a distance or a time, say so explicitly rather than presenting a guess as certainty.
Closing Declaration
Close with language confirming the truth of the statement. For matters executed inside the United States, the standard wording is: “I declare under penalty of perjury that the foregoing is true and correct. Executed on [date].” If you’re signing outside the country, add “under the laws of the United States of America.”3Office of the Law Revision Counsel. 28 USC 1746 – Unsworn Declarations Under Penalty of Perjury Leave space below for your signature, the date, and, if applicable, a notary block.
Notary or Unsworn Declaration
Not every sworn statement needs to be notarized. For federal matters, you can replace a traditional notarized affidavit with an unsworn written declaration that carries the same legal weight, provided you sign it under penalty of perjury with the closing language above.3Office of the Law Revision Counsel. 28 USC 1746 – Unsworn Declarations Under Penalty of Perjury Three situations still require a traditional oath: depositions, oaths of office, and any oath a specific statute requires to be taken before a particular official.
The declaration option matters. For a federal court filing, a federal administrative proceeding, or a claim under federal regulations, you can often sign and date the document at home. The perjury penalties are identical, so it isn’t treated less seriously. If the receiving court or agency specifically requires notarization, or the matter is governed by state law rather than federal law, a declaration may not be accepted. Confirm the filing requirements before deciding.
Signing Before a Notary
When notarization is required, sign in person before an official authorized to administer oaths. That’s usually a notary public, but federal law also recognizes anyone authorized under local law, which typically includes judges, court clerks, and certain military officers.4Office of the Law Revision Counsel. 5 USC 2903 – Oath Authority to Administer
What to Bring
Bring a current, unexpired government-issued photo ID: a state driver’s license, state ID card, U.S. passport, or military ID works in virtually every jurisdiction. Some states accept additional forms; others have a narrower list. If your ID is expired, call the notary first, because acceptance varies by state. Bring the complete but unsigned statement. Signing must happen in the notary’s presence.
What Happens
The notary verifies your identity and administers the oath or affirmation. You verbally confirm the contents are true, then sign while the notary watches. The notary adds their signature, seal, and commission information to a notarial certificate, confirming that you personally appeared and swore to the statement.
Fees and Remote Notarization
Notary fees are set at the state level. Most states cap in-person notarization somewhere between $2 and $15 per signature. A growing number of states now permit remote online notarization, where you appear by live video. Remote fees tend to run higher, up to $25 in some states, and the process typically involves multi-step identity verification: you show your ID on camera, the platform’s software analyzes the document, and you may answer computer-generated questions drawn from your personal history. As of 2025, over 40 states have enacted permanent laws authorizing remote online notarization.
Fixing Mistakes
Errors caught before notarization are easy. Draw a single line through the incorrect text, write the correction nearby, and initial and date the change. Skip correction fluid or heavy scribbles, since anything that looks like an attempt to hide the original raises questions about the document’s integrity.
Errors caught after notarization are harder. In most situations, the safest approach is to draft a new corrected statement and have it notarized again. Most states do not allow a notary to modify a completed notarial certificate. If the error is only in the certificate itself, the notary may be able to attach a corrected one, but this varies. When in doubt, start over with a clean document.
Submitting the Statement
Make at least two copies of the fully executed document before you send the original. One is for your records; keep the other as a backup in case the original is lost in transit. Confirm the correct recipient and delivery method. Some courts require hand delivery or electronic filing through a specific system; some agencies accept mailed originals.
If you mail it, use certified mail with return receipt requested. A signed return receipt creates proof of delivery, which matters if there’s ever a dispute about whether you met a filing deadline.5eCFR. 45 CFR 1149.16 – What Constitutes Proof of Service If you deliver in person or through an attorney, ask for a file-stamped copy as your receipt. Watch the deadline: a well-drafted sworn statement that arrives a day late may be rejected outright.
