At the time of commencing any action or proceeding in any court of this state, the foreign fiduciary shall file with the court an authenticated copy of the fiduciary's appointment, and of the fiduciary's official bond, if the fiduciary has given a bond. If the court believes that the security furnished by the fiduciary in the domiciliary administration is insufficient to cover the proceeds of the action or the proceeding, or for any other reason or cause, it may at any time order the action or proceeding stayed until sufficient security is furnished in the action or proceeding.
