N.J. Stat. § 16:13-10
The trustees of any two or more Reformed congregations, by whatever name known in their charters or acts of incorporation, may form one joint corporation in the following manner:
Such trustees shall renounce or forego their separate charters or acts of incorporation by mutual consent in writing, under their hands and seals, which writing shall signify their intention to become one joint corporation and shall be recorded in the office of the county clerk. Such trustees shall also form themselves into one corporation in accordance with this chapter. Upon recording such writing, and after such joint incorporation, the former separate corporations shall cease and be dissolved, and all real and personal property held by them separately, shall vest in the trustees of the joint corporation, which trustees shall be the legal successors in office of the former separate bodies, and be liable to their debts.
