Self-proving will NJ documents can save your family months of hassle and thousands in legal fees after you pass away. As an estate-planning attorney who has drafted hundreds of wills for New Jersey residents over the past twelve years, I’ve seen firsthand how a properly executed self-proving affidavit eliminates the need for witnesses to appear in Surrogate’s Court years later. In this comprehensive guide, I’ll explain exactly what a self-proving will in New Jersey is, why it matters under N.J.S.A. 3B:3-4 and 3B:3-5, and—most importantly—give you a free, attorney-drafted New Jersey self-proving affidavit template you can download and use today.
A self-proving will is a standard last will and testament that includes a notarized affidavit signed by the testator (you) and two disinterested witnesses at the same time as the will signing. When this affidavit is attached, the Surrogate’s Court can probate the will without requiring your witnesses to come to court or submit separate sworn statements after your death.
According to the New Jersey Statutes (N.J.S.A. 3B:3-4), a will may be simultaneously executed, attested, and made self-proved by attaching a sworn affidavit in the exact form required by law. Without this affidavit, New Jersey courts typically require at least one witness to testify in person or provide a deposition—something that becomes difficult or impossible when witnesses have moved to Florida or simply can’t be located years later.
| Requirement | Details | Statute |
|---|---|---|
| Testator age | 18 or older and of sound mind | N.J.S.A. 3B:3-1 |
| In writing | Typed or computer-printed (handwritten wills are riskier) | N.J.S.A. 3B:3-2 |
| Signed by testator | At the end of the document | N.J.S.A. 3B:3-2 |
| Two witnesses | Must watch you sign and sign themselves | N.J.S.A. 3B:3-2 |
| Notarized affidavit | Signed by you and both witnesses at the same ceremony | N.J.S.A. 3B:3-4 |
Below is my current, fully compliant New Jersey self-proving affidavit template that meets the exact language required by N.J.S.A. 3B:3-4 and 3B:3-5. I update this template every January to reflect any legislative changes (none as of November 2025).

The download includes:
Yes. New Jersey still requires two witnesses to the will itself. The affidavit is an additional document that makes their testimony “self-proving.”
No. New Jersey only permits self-proving affidavits with formally witnessed wills (see N.J.S.A. 3B:3-4).
Most states honor properly executed out-of-state self-proving affidavits under the Uniform Probate Code or comity, but always check with local counsel for ancillary probate.
No. It speeds up the probate process but does not eliminate it. Only revocable living trusts completely avoid probate.
In my twelve-plus years of practice, I’ve never had a properly executed self-proving will rejected by any New Jersey Surrogate. The small effort of gathering two witnesses and a notary at signing time pays enormous dividends for your loved ones later.
