“Further affiant sayeth naught” is a traditional closing line in a sworn affidavit that means the person making the statement has nothing more to add. It sits just above the signature block and signals that the affiant’s testimony is finished. The phrase is archaic, not required, and many modern affidavits leave it out entirely.
Breaking the Phrase Down Word by Word
Each word carries a specific meaning that becomes obvious once translated:
- “Further” means additional, or beyond this point.
- “Affiant” is the person who swears to the truth of the affidavit. The term comes from the Medieval Latin affidare, meaning “to pledge faith.”
- “Sayeth” is an Early Modern English form of “says,” the same register used in the King James Bible.
- “Naught” is an older word for “nothing.”
Put together, the sentence translates to: “The person making this sworn statement has nothing further to say.” You will also see variants like “further affiant saith not” and “further deponent sayeth naught.” They all mean the same thing.
Where the Phrase Appears and What It Signals
An affidavit is a written statement made under oath, used as evidence in everything from summary judgment motions to search warrant applications. Federal Rule of Civil Procedure 56 allows parties to rely on affidavits when arguing that facts are undisputed, and requires each one to be based on personal knowledge and to state facts that would be admissible as evidence.1Cornell Law School (LII / Legal Information Institute).

The closing phrase functions as a formal full stop. It tells the court that the affiant’s testimony is complete and that nothing further should be inferred from the document’s silence on other topics.2Legal Information Institute (LII) / Cornell Law School. Further Affiant Sayeth Naught If an opposing attorney later asks why the affidavit didn’t address a particular issue, the closing reinforces that the affiant deliberately confined the statement to what appears on the page.
Is It Legally Required?
No. No federal statute or court rule requires this specific language for an affidavit to be valid. The essential elements of a valid affidavit are the affiant’s identity, a statement of facts based on personal knowledge, an oath or affirmation, the affiant’s signature, and notarization or another form of official acknowledgment. A period at the end of the last factual sentence does the same mechanical work.
The phrase survives because legal culture is conservative. Attorneys reuse templates that courts have accepted, and stripping out familiar language feels riskier than leaving it in. No court has invalidated an otherwise proper affidavit because it lacked this closing line, and legal writing experts have long questioned what it adds beyond the period at the end of the final sentence.2Legal Information Institute (LII) / Cornell Law School.

Modern Alternatives
Legal drafting has moved toward plain language. A modern affidavit might close with “I have nothing further to state,” or simply end after the last factual sentence with no ceremonial sign-off at all.
Federal law goes further and allows an unsworn declaration to replace a notarized affidavit in almost any context. Under 28 U.S.C. § 1746, the document must be in writing, dated, signed, and include language substantially like: “I declare under penalty of perjury that the foregoing is true and correct.”3Office of the Law Revision Counsel. 28 U.S. Code 1746 – Unsworn Declarations Under Penalty of Perjury That format skips the notary, the oath ceremony, and any traditional closing phrase. The only exceptions are depositions and oaths of office, which still require the traditional sworn format.
Federal courts treat declarations and affidavits as equivalent for most purposes, including summary judgment. False statements in either carry the same perjury exposure. The practical result is that “further affiant sayeth naught” is fading from federal practice, where many attorneys now default to the declaration form.
Electronic filing has not resurrected the phrase either. The federal E-SIGN Act provides that when a law requires a signature, notarization, or verification under oath, an electronic signature satisfies that requirement so long as it meets all other applicable legal standards.4Office of the Law Revision Counsel. 15 U.S. Code 7001 – General Rule of Validity The Act does not mandate any particular closing language.
Why the Closing Matters for Perjury
The phrase carries an implicit warning: everything in the document is true, and the affiant has disclosed everything they intended to disclose. That matters because lying in an affidavit is a crime.
Under federal law, perjury occurs when a person who has taken an oath willfully states something they do not believe to be true about a material fact. The penalty is a fine, up to five years in prison, or both.5Office of the Law Revision Counsel. 18 USC 1621 – Perjury Generally State perjury laws vary in their exact wording and penalties, but virtually all require the same core elements: a false statement, made knowingly, about a fact that could influence the outcome of the proceeding.
Intentional omissions can create separate exposure. Another federal statute makes it a crime to knowingly conceal a material fact in any matter within the jurisdiction of the federal government, also punishable by up to five years in prison.6Office of the Law Revision Counsel. 18 U.S. Code 1001 – Statements or Entries Generally This is where the closing phrase takes on practical bite. By stating that the affiant “sayeth naught” beyond what appears in the document, the affiant draws a clear line: no additional relevant information is being held back. If it is, the closing itself becomes evidence of the intent to mislead.
Honest mistakes generally do not trigger perjury charges. Prosecutors must prove that the false statement was willful, not merely careless. A wrong date or a garbled detail is not the same as fabricating facts or hiding inconvenient ones.
State Variation
Affidavit practice is not uniform across the country. Some states still expect or encourage traditional affidavit language, including archaic closing phrases. Others have adopted plain-language rules for court filings that nudge attorneys away from formulations like “further affiant sayeth naught.” The divergence extends past closing lines: some jurisdictions require a formal “jurat” certificate from the notary confirming the oath was administered, others accept a simple acknowledgment, and many now allow unsworn declarations under penalty of perjury to substitute for sworn affidavits in most circumstances, following the federal model.3Office of the Law Revision Counsel. 28 U.S. Code 1746 – Unsworn Declarations Under Penalty of Perjury
Before filing anything sensitive, check the specific rules of the court or agency that will receive it. The closing phrase itself is safe to include or omit in most places, but the surrounding requirements — oath format, notarization, acceptable identification, and permissible use of an unsworn declaration — depend on the jurisdiction.
