N.J.A.C. 18:26-2.14 (2014)
§ 18:26-2.14 Composition of taxes on certain transfers
(a) In the case of a transfer or transfers made subject to a contingency or condition which renders a definite determination of the transfer inheritance tax due impossible, the Transfer Inheritance Tax Branch may enter into a composition or compromise of the tax based upon the immediate payment and final disposition of the tax.
(b) The composition or compromise of the tax is determined after a consideration of the amount of taxes that may become due as a result of the various contingencies or conditions, the present values thereof and the probability of the contingencies or conditions to which the transfers are subject occurring. The purpose of a composition is to permit an immediate, fair and equitable adjustment of the tax due, rather than holding the liability for taxes suspended for an indefinite period.
(c) The payment of the taxes provided for in such composition shall be conclusive in favor of the executor or trustee as against the interests of such cestuis que trustent as may possess present rights of enjoyment or fixed, absolute or indefeasible rights of future enjoyment, or of such as would possess such rights in the event of the immediate termination of a particular transfer.
