Updated August 3, 2026. Quick answer for New Jersey: nobody publishes a reliable, state-specific median for what a will costs here, and the figures you will see quoted — including ours — are national. Anyone showing you a precise New Jersey number is estimating. What is genuinely New Jersey-specific, and what actually decides whether your will works, is how it has to be executed. The detail worth knowing before you sign anything: in New Jersey the will itself needs no notary, but the self-proving affidavit that spares your executor a witness hunt does — which is the single most confused point in this whole subject.
The honest position on New Jersey pricing
We publish a national attorney median for a simple will of $625 (middle 50% $450–$1,000) and a DIY platform range of $129–$599. Attorney figures are the national medians from the LegalTemplates 2026 survey of 909 firms, verified July 23, 2026. They are national, not state-specific — see the note on state pricing below. Geographic multipliers are widely republished, but the primary source for them blocks automated verification, so we will not apply one to New Jersey and present the result as a New Jersey figure. When a defensible state-level dataset exists, this page will carry it and say where it came from.
What New Jersey law actually requires
This is the part that is genuinely state-specific, and the part that decides whether the document works at all. Every line below is read from the statute, with the citation attached:
- Witnesses: 2. N.J.S.A. 3B:3-2
- Notary required for the will to be valid: no. A notary is not what makes a will valid here — the witnesses are. N.J.S.A. 3B:3-2
- Self-proving affidavit: available. Signing one at the same time as the will is what saves your executor from tracking witnesses down years later. N.J.S.A. 3B:3-4
The full 44-jurisdiction comparison is on what each state requires for a will to be valid.
Does New Jersey give you a free form?
No. Only four states we can verify publish a complete statutory will form in their own code: California, Maine, Michigan and Wisconsin. In New Jersey your realistic routes are a DIY platform, a flat-fee attorney will, or an hourly engagement if the estate is complicated. New Mexico is often listed as a fifth statutory-form state; we could not reach its official code to confirm it, so we leave it out rather than repeat it.
What skipping it costs in New Jersey
A will does not avoid probate — it directs it. What it prevents is the estate being distributed by New Jersey’s intestacy statute instead of by you, and it lets you name the executor rather than leaving the court to appoint one. The arithmetic on the other side is on what probate costs in New Jersey.
If a DIY will is the right route for you in New Jersey
Where the estate is straightforward and none of the complications above apply, a properly executed DIY will does the job, and how it is signed matters far more than where the document came from. LawDepot builds a state-specific last will and testament, which you then sign and witness under the New Jersey rules above.
