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.
