N.J.S.A. 3B:3-2 provides that,
a. Except as provided in [N.J.S.A.] 3B:3-3, a will shall be:
(1) in writing;
(2) signed by the testator or in the testator's name by some other individual in the testator's conscious presence and at the testator's direction; and
(3) signed by at least two individuals, each of whom signed within a reasonable time after each witnessed either the signing of the will as described in paragraph (2) or the testator's acknowledgment of that signature or acknowledgment of the will.
b. A will that does not comply with subsection a. is valid as a writing intended as a will, whether or not witnessed, if the signature and material portions of the document are in the testator's handwriting.
c. Intent that the document constitutes the testator's will can be established by extrinsic evidence, including for writings intended as wills, portions of the document that are not in the testator's handwriting.
Moreover, in In re Probate of Last Will and Testament of Catelli, 361 N.J. Super. 478 (App. Div. 2003), we stated that we appreciated
the trial judge's concern that a testatrix with a severe visual impairment is ordinarily unable, without the intervention of a neutral person, to determine if the will as drafted accurately memorializes her testamentary instructions. The same, of course, is true of a testator who cannot read by reason of illiteracy. But whether the statutory provisions for the witnessing and execution of the wills of such testators should be augmented to require that the pre-execution reading of the will to the testator be by a disinterested person is, in our view, a matter within the province of the Legislature.
