N.J. Stat. § 3B:10-4
Where the total value of the real and personal assets of the estate of an intestate will not exceed $20,000 and the intestate leaves no surviving spouse, partner in a civil union, or domestic partner, and one of his heirs shall have obtained the consent in writing of the remaining heirs, if any, and shall have executed before the Surrogate of the county where the intestate resided at his death, or, if then nonresident in this State, where any of the intestate's assets are located, or before the Superior Court, the affidavit herein provided for, shall be entitled to receive the assets of the intestate of the benefit of all the heirs and creditors without administration or entering into a bond. Upon executing the affidavit, and upon filing it and the consent, he shall have all the rights, powers and duties of an administrator duly appointed for the estate and may be sued and required to account as if he had been appointed administrator by the Surrogate or the Superior Court.
The affidavit shall set forth the residence of the intestate at his death, the names, residences and relationships of all of the heirs and specifically the nature, location and value of the real and personal assets and also a statement that the value of the intestate's real and personal assets will not exceed $20,000.
The consent and the affidavit shall be filed and recorded, in the office of the Surrogate or, if the proceeding is before the Superior Court, then in the office of the clerk of that court. Where the affiant is domiciled outside this State, the Surrogate may authorize in writing that the affidavit be executed in the affiant's domicile before any of the officers authorized by R.S. 46:14-6.1 to take acknowledgments or proofs.
