New Jersey Acceptance of Testamentary Trusteeship is a legal document that is filed with the court when a trustee is appointed to administer a decedent's estate. The document includes information about the trustee, such as the trustee's name, address, and contact information. It also includes a description of the trust, its terms and conditions, and the fiduciary duties of the trustee. There are two types of New Jersey Acceptance of Testamentary Trusteeship: 1) Formal Acceptance, which is filed in the Surrogate's Court of the county where the decedent resided; and 2) Informal Acceptance, which is used when the trustee is not formally appointed by the court. With Informal Acceptance, the trustee is required to provide an affidavit to the court, attesting to their qualifications and willingness to serve as trustee.
