In almost every situation, yes: an affidavit needs to be notarized to have legal effect. Courts, recording offices, and government agencies treat an unnotarized affidavit as an ordinary written statement with no sworn status, and they will generally reject it. The main exception is the unsworn declaration under federal law, which lets you sign “under penalty of perjury” instead of appearing before a notary in matters governed by federal law, regulation, or court rule.
When Notarization Is Required
Courts are the most common setting. When you submit an affidavit as evidence in a motion, hearing, or other filing, a judge will generally refuse to consider it unless it was properly sworn before a notary. An unnotarized statement carries no more weight than a letter written at your kitchen table.
Real estate transactions are another area where notarization is essentially non-negotiable. Affidavits confirming ownership, clearing title defects, or attesting to a property’s condition must typically be notarized before a county recording office will accept them for filing. Estate-related affidavits used to transfer property follow similar rules.
Government applications frequently require notarized affidavits as well. The U.S. State Department, for example, requires that a birth affidavit submitted with a passport application be signed in front of a passport agent, passport acceptance agent, or notary.1U.S. Department of State. Form DS-10 Birth Affidavit Immigration filings, name change petitions, and various licensing applications carry similar requirements.
One technical point worth checking on the finished document: the notary certificate should read “subscribed and sworn to before me,” which is the language of a jurat. If it reads “acknowledged before me,” the notary performed the wrong notarial act, and the affidavit can be rejected on that basis alone.
The Unsworn Declaration Alternative
Federal law provides a real exception. Under 28 U.S.C. § 1746, you can substitute an unsworn written declaration for a notarized affidavit in any matter governed by federal law, regulation, or court rule.2Office of the Law Revision Counsel. 28 USC 1746 – Unsworn Declarations Under Penalty of Perjury Instead of appearing before a notary, you include specific language stating that you declare “under penalty of perjury” that the information is “true and correct,” then sign and date the document.
The required language depends on where you sign. Within the United States: “I declare under penalty of perjury that the foregoing is true and correct.” Outside the country, you add “under the laws of the United States of America” after “under penalty of perjury.”2Office of the Law Revision Counsel. 28 USC 1746 – Unsworn Declarations Under Penalty of Perjury Getting the wording wrong, or omitting it, can cause the document to be treated as unsworn.
Two limits matter. First, the statute explicitly excludes depositions and oaths required before a specific official other than a notary; those still require the traditional process. Second, state courts and state agencies are not bound by the federal statute. Many states have adopted their own versions of unsworn declaration laws, but the specifics vary, and some restrict the option to certain types of proceedings. Before relying on an unsworn declaration in a state matter, confirm the state has authorized its use for your situation.
What Happens if You Skip Notarization
The immediate consequence is rejection. A court, recording office, or government agency will refuse to accept the document, and you start over. In litigation, that can mean a missed filing deadline. In a real estate closing, it can delay or derail the transaction. For a government application, it usually means denial or a request to resubmit, adding weeks to the timeline.
Beyond rejection, an unnotarized affidavit has no special legal standing. It cannot serve as sworn testimony, support a motion, or satisfy a requirement that calls for a sworn document.
Perjury Applies Either Way
The oath during notarization is not ceremonial, and neither is the “under penalty of perjury” language on a declaration. Knowingly making a false statement in either one exposes you to perjury charges. Under federal law, perjury carries a maximum sentence of five years in prison, a fine, or both. The federal perjury statute also reaches unsworn declarations made under 28 U.S.C. § 1746.3Office of the Law Revision Counsel. 18 USC 1621 – Perjury Generally Skipping the notary does not reduce your criminal exposure. State perjury penalties vary but follow a similar framework, with most treating perjury as a felony.
How to Get an Affidavit Notarized
The single most important rule: do not sign the affidavit before you meet the notary. Because affidavits require a jurat, the notary must watch you sign. Show up with a pre-signed document and the notary cannot complete the notarization, which means printing a fresh copy. This is the mistake that catches people most often.
The process from there:
- Fill in the affidavit completely but leave the signature line blank.
- Bring a government-issued photo ID such as a driver’s license or passport.
- Sign in front of the notary after they verify your identity.
- Answer the oath out loud. The notary will ask you to swear or affirm the contents are true, and a nod does not count.
- Let the notary sign and apply the seal, completing the jurat.
Where to Find a Notary
Notaries work at banks, credit unions, shipping stores, law offices, and many real estate offices. Banks often provide notarization at no charge for account holders. Independent notaries and shipping centers typically charge from a few dollars up to around $15 per signature for in-person service, though fees vary by state.
Remote Online Notarization
If you cannot get to a notary in person, remote online notarization is now available in 47 states and the District of Columbia.4National Association of Secretaries of State. Remote Electronic Notarization You and the notary complete the process over audio and video. Identity is verified through knowledge-based authentication questions and a live ID check on camera, and you sign electronically while the notary watches. Sessions generally cost more than in-person notarization, often around $25 per document. Before scheduling one, confirm the jurisdiction where your document will be filed accepts remote online notarizations, because a small number of states still limit which document types qualify.
