N.J. Stat. § 3B:12-55: When authority and responsibility of guardian terminate

The authority and responsibility of a guardian of the person or estate of a minor terminate upon the death, resignation or removal of the guardian or upon the minor's death, adoption, marriage or attainment of 18 years of age, but termination does not affect the guardian's liability for prior acts, nor his obligation to account for funds and assets of his ward. Resignation of a guardian does not terminate the guardianship unless it has been approved by a judgment of the court.
