New Jersey Statutes Appendix - Former Title 3A Administration of Estates Decedents and Others 3A § 3-13

When a devise or bequest is made by will to a child or other descendant of the testator or to a brother or sister or any descendant of a brother or sister of the testator, and such devisee or legatee shall, during the life of the testator, die testate or intestate leaving any child or any descendant of a child of such devisee or legatee surviving the testator, such devise or legacy shall not lapse but shall vest in any such child or descendant of a child of such devisee or legatee as if such devisee or legatee had survived the testator and died intestate. This section shall not apply where the testator shall by will have otherwise directed in regard to the children or descendants of such devisee or legatee.
