Declaration Under Penalty of Perjury
What the Declaration Under Penalty of Perjury Is and when it’s used
Why a clear Declaration Under Penalty of Perjury matters
A well-prepared declaration creates a concise, legally meaningful written record that can substitute for an affidavit in many administrative and court-adjacent processes, reduce processing delays, and limit disputes about factual statements.
Typical users and scenarios for this declaration
Use the declaration only when the receiving authority accepts unsworn written declarations; some courts or agencies still require notarized affidavits.
- Individual filers providing factual claims on tax or immigration forms, such as residency or income statements, where a sworn statement is required by the receiving agency.
- Attorneys or authorized representatives certifying factual attachments to filings where client facts must be verified in writing.
- Business officers or signatories certifying corporate statements for contracts, licensing, or statutory attestations where personal knowledge is asserted.

Frequently asked questions about declarations under penalty of perjury
-
Is a declaration the same as an affidavit?
A declaration is an unsworn written statement made under penalty of perjury and may substitute for an affidavit where allowed; an affidavit is typically sworn and notarized. Check the receiving authority’s rules before choosing one form over the other.
-
Can I sign electronically?
Electronic signatures are valid under the ESIGN Act and UETA where the recipient accepts them; ensure the electronic method meets any required authentication and that the recipient does not require a notarized oath.
-
What wording is required?
Use the perjury clause explicitly required by the recipient when specified (for example, the statement referencing penalty of perjury under U.S. or state law). If the agency provides exact language, use that wording verbatim.
-
Do I need a notary or witness?
Some recipients accept unsworn declarations while others require notarized affidavits or witness signatures; confirm acceptance criteria and remote notarization rules with the recipient or applicable state law.
-
What happens if information is false?
Willfully false statements can lead to criminal perjury charges, civil penalties, denial of benefits, and disciplinary consequences. Always verify facts and consult counsel if unsure.
-
How long should I keep the signed copy?
Retain the signed declaration and any supporting records for at least three years, and longer if industry rules apply (e.g., six years for HIPAA-related records).
