Any personal representative of a decedent, fiduciary of a person under a disability, or other fiduciary may submit to arbitration any suit or matter of controversy touching the estate or property of such decedent, or person under a disability or in respect to which he is trustee. And any submission so made in good faith, and the award made thereupon, shall be binding and entered as the judgment of a court, if so required by the agreement, in the same manner as other submissions and awards. No such fiduciary shall be responsible for any loss sustained by an award adverse to the interests of the person under a disability or beneficiary under any such trust, unless it was caused by his fault or neglect.
