Any trustee, committee, guardian, assignee, receiver, executor, administrator or other fiduciary shall be entitled to have any surety on the bond of the fiduciary or of any irrevocable letter of credit issuer discharged from liability thereon, and the fiduciary may file a new bond or irrevocable letter of credit as provided in this section. The fiduciary may, on written notice to the surety or letter of credit issuer and to all other interested persons, apply to the court that accepted the bond or irrevocable letter of credit, or to a judge thereof, praying that the surety or irrevocable letter of credit be discharged from liability thereon, and that the principal be allowed to file a new bond or irrevocable letter of credit and to account. Notice of the application shall be served on the surety or letter of credit issuer and on each of the persons interested, within the state, not less than 10 days prior to the date on which the application is to be made, unless it satisfactorily appears to the court or judge that the notice cannot with due diligence be served within the state, in which case notice may be given in such manner as the court or judge shall direct. Upon the return of the application, the principal may file a new bond or irrevocable letter of credit satisfactory to the court or judge, and therewith file an account of all proceedings, whereupon the court or judge shall proceed, upon due notice to all persons interested, to judicially settle the account and duly credit and charge the principal; and upon the trust fund or estate being found or made good and paid over or properly secured, the surety or letter of credit issuer shall be discharged from all liability.
