Notwithstanding any other provision of this probate code, the duly qualified fiduciary under a will admitted to probate in another state, may upon application be appointed fiduciary in this state, after said will has been admitted to probate in this state, provided that a resident fiduciary be appointed to serve with the nonresident fiduciary; provided further, however, that, for good cause shown, the court may appoint, the nonresident fiduciary to act alone without the appointment of a resident fiduciary.
