New Jersey Statutes Title 3B. Administration of Estates Decedents and Others 3B § 12-64

a. The authority and responsibility of a guardian of the person or estate of an incapacitated person terminate upon:

b. However, termination does not affect the guardian's liability for prior acts, nor the guardian's obligation to account for funds and assets of the ward.

c. Notwithstanding the termination of the guardianship, the guardian may make final burial and funeral arrangements if the body remains unclaimed for five days and may pay for burial and funeral costs, Surrogate fees of administration, probate and bond from the guardianship account. Resignation of a guardian does not terminate the guardianship unless it has been approved by a judgment of the court.

d. Upon the death of an incapacitated person the guardian shall provide written notification to the Surrogate and shall provide the Surrogate with a copy of the death certificate within seven days of the guardian's receipt of the death certificate.
