Both New Jersey and New York require two witnesses for a valid will, but the rules differ on timing, the self-proving affidavit, and the interested-witness rule. This guide compares the two states side by side using current statutory sources.

Key Difference
New Jersey (N.J.S.A. 3B:3-2) and New York (EPTL § 3-2.1) both require two witnesses for a valid will. The critical distinction is timing: New York requires witnesses to sign within 30 days of the testator's signing; New Jersey imposes no equivalent time limit. Both states have an interested-witness rule that voids a gift to a witness unless two other disinterested witnesses also sign.
A will that is not properly executed is not a valid will. Improper execution — wrong number of witnesses, witnesses who are disqualified, or failure to meet timing requirements — can result in the document being denied probate, leaving the estate to pass under the state's intestacy laws instead of the testator's wishes.
New Jersey and New York share the two-witness standard but differ on several procedural details that matter in practice, particularly for signings that take place over multiple sessions or in institutional settings.
| Requirement | New Jersey | New York |
|---|---|---|
| Number of witnesses | 2 (N.J.S.A. 3B:3-2) | 2 (EPTL § 3-2.1) |
| Witness signing deadline | No statutory time limit; must sign in presence of testator and each other | Must sign within 30 days of testator's signing (EPTL § 3-2.1(a)(4)) |
| Witnesses must sign in each other's presence | Not required — each witness must sign within a reasonable time after witnessing the testator's signing or acknowledgment; simultaneous presence of both witnesses is not required (N.J.S.A. 3B:3-2) | Not required — each witness must sign within 30 days of the testator's signing; witnesses need not be present simultaneously (EPTL § 3-2.1) |
| Notarization required | Not required for a valid will; required only for self-proving affidavit | Not required for a valid will; required only for self-proving affidavit |
| Self-proving affidavit | Available under N.J.S.A. 3B:3-4; requires notarization; simplifies probate | Available under EPTL § 3-2.1(f); requires notarization; simplifies probate |
| Interested-witness rule | Gift to witness void unless 2 other disinterested witnesses also sign (N.J.S.A. 3B:3-2) | Gift to witness void unless 2 other disinterested witnesses also sign (EPTL § 3-2.1(b)) |
| Minimum witness age | Must be 'competent'; no explicit age stated in statute | Must be 18 or older (EPTL § 3-2.1(a)(1)) |
| Holographic wills (handwritten, unwitnessed) | Valid if entirely in testator's handwriting and signed (N.J.S.A. 3B:3-2(b)) | Not valid for New York residents; only valid for military personnel under limited conditions (EPTL § 3-2.2) |

Under N.J.S.A. 3B:3-2, a New Jersey will is valid if it is signed by the testator (or by another person in the testator's conscious presence and at the testator's direction) and is signed by at least two individuals, each of whom signed within a reasonable time after witnessing either the signing of the will or the testator's acknowledgment of the signature or the will.
New Jersey does not impose a fixed deadline for witness signatures. The standard is 'within a reasonable time' after witnessing the testator's signing or acknowledgment of the will. Simultaneous presence of both witnesses is not required — each witness must sign within a reasonable time after witnessing the testator, but the two witnesses need not be present at the same time.
New Jersey recognizes holographic wills — wills that are entirely in the testator's handwriting and signed — without any witness requirement. This is a significant departure from New York, which does not recognize holographic wills for civilian residents.
The self-proving affidavit under N.J.S.A. 3B:3-4 allows the will to be admitted to probate without requiring the witnesses to testify. It requires notarization and is executed at the time of the will signing or afterward.
Under EPTL § 3-2.1, a New York will must be signed by the testator at the end of the will, in the presence of each of the attesting witnesses, or acknowledged to each of them. The testator must declare to each witness that the instrument is the testator's will.
Each witness must sign within 30 days of the testator's signing. This is a hard statutory deadline — not a 'reasonable time' standard. A witness who signs on day 31 has not validly attested the will under New York law.
New York does not require witnesses to sign in each other's presence. Each witness must sign in the testator's presence, but the two witnesses need not be present simultaneously. This differs from New Jersey's simultaneous-presence requirement.
New York does not recognize holographic wills for civilian residents. An unwitnessed handwritten will is not valid in New York regardless of how clearly it expresses the testator's intent.
The self-proving affidavit under EPTL § 3-2.1(f) allows probate without live witness testimony. It requires notarization and is typically executed at the time of the will signing.
