How to Make a Will in New Jersey: Requirements, Witnesses, and Common Mistakes

New Jersey doesn't require an attorney to draft a will. Under N.J.S.A. 3B:3-2, a will is legally valid if you follow specific execution rules — and the county surrogate's office will accept it for probate regardless of who drafted it. But the execution details matter. A single misstep with witness signatures can send your family into a formal Superior Court hearing instead of a routine surrogate filing.

Here's exactly what New Jersey law requires, what it doesn't, and the mistakes that actually cause problems.

Legal Requirements for a Valid New Jersey Will

Under N.J.S.A. 3B:3-2, a valid will requires:

• You must be at least 18 years old and of sound mind. "Sound mind" means you understand the nature of your property, who would naturally inherit it, and that you are creating a will.
• The will must be in writing. Typed, printed, or handwritten — New Jersey accepts all three, though handwritten wills create extra procedural hurdles (more on this below).
• You must sign the will. Your signature goes at the end. If you're physically unable to sign, another person can sign for you in your presence and at your direction.
• Two adult witnesses must sign. Each witness must either watch you sign or hear you acknowledge that the signature is yours. They then sign within a reasonable time.

New Jersey does not require notarization to make a will valid. It does not require witnesses to be disinterested (a beneficiary can technically serve as a witness, though this creates complications). And it does not require the witnesses to be present simultaneously — each can witness and sign at separate times, as long as each occurs within a reasonable timeframe.

The Self-Proving Affidavit: Why You Should Always Add One

The most consequential addition to a New Jersey will isn't a trust provision or a tax clause — it's the self-proving affidavit under N.J.S.A. 3B:3-4.

This is a notarized statement signed by you and your two witnesses confirming that all execution requirements were followed. It creates a legal presumption of validity that allows the county surrogate to admit the will to probate without requiring the witnesses to appear.

Without this affidavit, the surrogate must obtain a witness deposition. If a witness has moved, become incapacitated, or died, proving the will becomes exponentially more difficult and expensive — potentially requiring a formal hearing in the Superior Court Chancery Division.

The affidavit can be added at the time of signing or at any point afterward. Adding it costs nothing beyond a notary fee (typically $2.50 per signature in NJ). Skipping it can cost your executor months of delay and hundreds in legal fees.

Handwritten (Holographic) Wills in New Jersey

New Jersey recognizes holographic wills under N.J.S.A. 3B:3-2, but with a critical procedural difference: the signature and all material provisions must be in your own handwriting, and no witnesses are required.

The catch is that holographic wills cannot be probated informally at the county surrogate. They require a formal hearing in the Superior Court Chancery Division, Probate Part, where witnesses must testify to authenticate your handwriting. This process is significantly more expensive and time-consuming than standard surrogate probate.

A typed will with two witnesses and a self-proving affidavit is almost always the better choice — even if you're drafting it yourself at your kitchen table.

Electronic Wills

New Jersey has introduced the Uniform Electronic Wills Act, which permits a will to be drafted, signed, and maintained in electronic format. The electronic signature must be affixed by the testator (or by someone acting in the testator's conscious physical or electronic presence at their direction) and witnessed electronically.

The practical reality is that electronic wills are still uncommon and many institutions haven't updated their processes to accept them. For most families, a printed will with wet-ink signatures remains the path of least resistance.

What Your New Jersey Will Should Include

Beyond the legal execution requirements, a complete New Jersey will addresses these elements:

Executor designation. Name a primary and successor executor. If your executor lives outside New Jersey, some county surrogates require them to post a surety bond unless you explicitly waive this requirement in the will.

Guardian nomination. If you have minor children, your will is the only place to formally nominate a personal guardian under N.J.S.A. 3B:12-1. Without this, the court decides.

Specific bequests. Individual items or dollar amounts to named people. Be precise — "my jewelry" invites disputes; "the 2-carat diamond engagement ring in my bedroom safe" does not.

Residuary clause. Everything not covered by specific bequests flows through this provision. Without one, unaddressed assets pass under New Jersey intestacy law regardless of your other wishes.

Digital asset authority. Under the Uniform Fiduciary Access to Digital Assets Act (N.J.S.A. 3B:14-61.1), you can grant your executor authority to access online accounts, cryptocurrency keys, and cloud storage. Without explicit language, custodians like Google and Facebook can refuse access to your executor.

Inheritance tax awareness. If any beneficiary falls into Class C (siblings, in-laws) or Class D (friends, unmarried partners, nieces, nephews), they face inheritance tax of 11% to 16%. Structuring bequests to minimize Class C/D exposure — such as redirecting assets through life insurance, which is fully exempt from NJ inheritance tax — is a legitimate planning strategy.

Common Mistakes That Invalidate New Jersey Wills

Signing without witnesses present. The witnesses must see you sign or hear you acknowledge the signature. A will you signed alone and then showed to witnesses later is technically defective.

Using only one witness. New Jersey requires two. One is insufficient.

Failing to revoke prior wills. New Jersey law doesn't automatically revoke a prior will when you execute a new one unless the new will explicitly states it does, or the two are irreconcilably inconsistent. Include a revocation clause.

Assuming divorce revokes everything. Under N.J.S.A. 3B:3-14, divorce automatically revokes bequests and fiduciary appointments to your former spouse in your will. But it doesn't affect beneficiary designations on life insurance, retirement accounts, or POD/TOD accounts — those must be updated separately.
