New Jersey Statutes Appendix - Former Title 3A Administration of Estates Decedents and Others 3A § 3-11

If a testator, having any child born at the time of the making of his will, shall, at his death, leave any child born after the making thereof, or any issue of any such after-born child, such after-born child or his issue, if neither provided for by settlement nor disinherited by the testator, shall take the same share as if such testator had died intestate.

Toward raising any such share, the devisees and legatees and their representatives shall contribute proportionately out of the part devised or bequeathed therein to them.
