New Jersey Statutes Title 3B. Administration of Estates Decedents and Others 3B § 17-13

Unless the governing instrument expressly provides otherwise, an instrument settling or waiving an account, executed by all persons whom it would be necessary to join as parties in a proceeding for the judicial settlement of the account, shall be binding and conclusive on all other persons who may have a future interest in the property to the same extent as that instrument binds the person who executed it.
