A valid affidavit in New Jersey is a written statement of facts, based on personal knowledge, signed by the person making it (the affiant) before a notary or other authorized officer who administers an oath or affirmation. But before you go looking for a notary, know this: New Jersey affidavit requirements often let you skip notarization altogether. For most court filings, a signed certification under Court Rule 1:4-4 carries the same legal weight as a sworn affidavit, with no notary involved.
Certification or Full Affidavit
The first question to settle is which format your situation actually calls for. Under Court Rule 1:4-4(b), any affidavit, oath, or verification the court rules require can be replaced with a written certification. The certification must include this exact language just above your signature: “I certify that the foregoing statements made by me are true. I am aware that if any of the foregoing statements made by me are wilfully false, I am subject to punishment.” You sign, you date, you file. No oath. No notary. No fee.
A certification works for almost anything filed with a New Jersey court: motion papers, proof of service, factual submissions in support of an application. The penalty for a false certification is the same as the penalty for a false affidavit, which is why courts accept them interchangeably.
A full notarized affidavit is still required when a statute outside the court rules demands one. Real estate transactions, filings with the Motor Vehicle Commission, tax filings, certain probate matters, and documents intended for use outside New Jersey typically call for the traditional sworn-and-notarized version. When in doubt, look at the source of the requirement. If it comes from the court rules, a certification will almost always do. If it comes from a statute or an agency form, follow the form.
What a New Jersey Affidavit Must Contain
A properly formatted New Jersey affidavit opens with a venue block identifying the state and county where the oath will be administered. Directly below, the affiant is identified by full legal name and address, and where relevant, by their connection to the matter.
The body sets out the facts in numbered paragraphs, one point per paragraph. Every statement must rest on the affiant’s personal knowledge. Speculation, hearsay, and secondhand information do not belong in an affidavit. The language should be plain and factual.
Near the end, the affidavit includes a declaration that the statements are true and made under penalty of perjury. The affiant signs on a signature line, and below that line sits the jurat: a separate block reserved for the officer administering the oath. The jurat records the date, confirms the affiant personally appeared and was sworn, and is completed and signed by the officer.1State of New Jersey Department of the Treasury. Affidavit of Identity
Who Can Administer the Oath
New Jersey does not limit affidavit oaths to notaries public. Under N.J.S.A. 41:2-1, the officers authorized to administer oaths and take affidavits include notaries, New Jersey licensed attorneys, judges of courts of record, municipal judges, surrogates, county clerks and their deputies, municipal clerks, sheriffs, members of the state legislature, and certified court reporters, among others.2Justia. New Jersey Revised Statutes Section 41-2-1
In practice, this means any New Jersey attorney can swear you in and witness your signature. So can a municipal clerk at your local town hall, which is often the easiest option if you cannot readily find a notary.
Identity Verification and the Notary’s Duties
A notary who handles your affidavit has to verify who you are before administering the oath. New Jersey regulations recognize three methods. The notary may rely on personal knowledge of your identity if they know you through prior dealings. They may accept documentary proof: a passport, driver’s license, or government-issued non-driver ID card that is either current or expired no more than three years, or another government-issued ID bearing your signature or photograph at the notary’s discretion. Or they may accept the sworn word of a credible witness who personally appears and vouches for you.3Legal Information Institute. New Jersey Administrative Code 17:50-1.13 – Forms of Identification
After confirming your identity, the notary administers the oath or affirmation, watches you sign, and completes the jurat. The notary’s official stamp goes near their signature and must include their name, the words “Notary Public, State of New Jersey,” and the commission expiration date. The stamp must be clear enough to photocopy legibly.4Justia. New Jersey Revised Statutes Section 52-7-10.5 – Official Stamp
Fees are capped. A notary may charge no more than $2.50 per notarial act. Administering the oath is one act and executing the jurat is another, so a standard affidavit typically costs $5.00.5Legal Information Institute. New Jersey Administrative Code 17:50-1.18 – Fees for Notarial Services
Remote Online Notarization
You do not always have to appear in person. N.J.S.A. 52:7-10.10 permanently authorizes remote online notarization: a notary located in New Jersey may perform notarial acts over a live audio-video connection for a signer who is somewhere else.6Justia. New Jersey Revised Statutes Section 52-7-10.10 – Notarial Act Performed by Remotely Located Individual
Identity verification for a remote session is stricter than for an in-person visit. The notary must either already know you personally, have a credible witness vouch for you on the video connection, or use at least two different forms of identity proofing, meaning a third-party service that cross-references your personal information against public or private databases. Before their first remote notarization, the notary must also notify the State Treasurer and identify the technology they will be using.6Justia.

Fixing a Mistake After Signing
If you catch an error after the affidavit has been notarized, the safest course in most cases is to execute a new affidavit. For minor errors caught before notarization is complete, corrections can be made by drawing a line through the incorrect information, printing the correct information nearby, and having both the affiant and the notary initial and date the change. Only the notary who performed the original notarization may correct the certificate itself, because the jurat is that notary’s official record of what took place.
Penalties for a False Affidavit
A false affidavit in New Jersey is perjury. Under N.J.S.A. 2C:28-1, perjury occurs when a person makes a false material statement under oath in an official proceeding while not believing the statement to be true. A statement is “material” if it could have affected the outcome, even if the affiant thought the lie was unimportant. Perjury is a crime of the third degree, carrying three to five years in prison on conviction.7Justia. New Jersey Revised Statutes Section 2C-28-1 – Perjury
There is one narrow defense. If you retract the false statement during the same proceeding, before it causes irreparable harm, the retraction is an affirmative defense. Waiting until the other side exposes the lie is too late.
Certifications under R. 1:4-4 carry the same exposure. The certification language itself warns that willfully false statements subject the signer to punishment, and courts treat a false certification the same as a false affidavit for penalty purposes. Choosing the shorter format does not lower the stakes.
