New Jersey Statutes Appendix - Former Title 3A Administration of Estates Decedents and Others 3A § 2A-10

A will may refer to a written statement or list to dispose of items of tangible personal property not otherwise specifically disposed of by the will, other than money, evidences of indebtedness, documents of title, and securities and property used in trade or business. To be admissible under this section as evidence of the intended disposition, the writing must be either in the handwriting of the testator or be signed by him and must describe the items and the devisees with reasonable certainty. The writing referred to may be one in existence at the time of the testator's death, may be prepared before or after the execution of the will, may be altered by the testator after its preparation and may be a writing which has no significance apart from its effect upon the dispositions made by the will.
