(a) Whenever a trustee of an express trust is engaged in war service, as defined in this section, such trustee or any other person interested in the trust estate may present a petition to the supreme court or the surrogate's court, as the case may be, to suspend the powers of such trustee while he is so engaged and until the further order of the court, and if the suspension of such trustee will leave no person acting as trustee or leave a beneficiary of such trust as the only acting trustee thereof, the petition must pray for the appointment of a successor trustee, unless a successor has been named in the trust instrument and is not engaged in war service or is not for any other reason unable or unwilling to act as such trustee.

(b) For the purposes of this section, a trustee is engaged in war service in any of the following cases:

(1) If he is a member of the armed forces of the United States or of any of its allies, or if he has been accepted for such service and is awaiting induction.

(2) If he is engaged in any work abroad in connection with a governmental agency of the United States or with the American Red Cross Society or any other body with similar objectives.

(3) If he is interned in any enemy country or is in a foreign country or a possession or dependency of the United States and is unable to return to this state.

(4) If he is a member of the Merchant Marine or similar service.

(c) Where the application is made by a trustee engaged in war service, notice shall be given to such persons and in such manner as the court may direct. Where the application is made by any other person interested in the trust estate and the trustee is in the armed forces of the United States, notice shall be given to such trustee in such manner as the court may direct. In every other case, where the application is made by a person other than the trustee, notice thereof shall be given to such persons and in such manner as the court may direct.

(d) Upon the filing of the petition and proof of service of notice prescribed in paragraph (c), the court may, notwithstanding any other provision of law, suspend the trustee engaged in war service from the exercise of all of his powers and duties while engaged in such service and until the further order of the court. The order may further provide that the remaining trustee or, if there is none, the successor named in the trust instrument or appointed by the court may exercise all of the powers and be subject to all of the duties of the original trustee.

(e) The successor trustee shall be limited to commissions as computed under SCPA 2308 or 2309, whichever is applicable, upon income received and disbursed and upon principal disbursed. Commissions may also be allowed under 2308 or 2309 upon rents if he is authorized or required to collect the rents of and manage real property. In case of the resignation or removal of the suspended trustee, or in the event of such trustee's death, the foregoing basis for computing the commissions shall not apply and his commissions shall be computed in the same manner as those of any other trustee.

(f) When the suspended trustee ceases to be engaged in war service he may, upon application to the court and upon such notice as the court may direct, be reinstated as trustee if any of the duties of such office remain unexecuted. If the suspended trustee is reinstated the court shall thereupon remove his successor and make such other order as justice requires, but such removal shall not bar the successor from subsequently qualifying as a trustee if for any reason it thereafter becomes necessary to appoint a trustee.
