Section 3-718
Unless the terms of the will otherwise provide, every power exercisable by personal co-representatives may be exercised by the 1 or more remaining after the appointment of 1 or more is terminated, and if 1 of 2 or more nominated as co-representatives is not appointed, those appointed may exercise all the powers incident to the office.
Comment
This section applies where one of two or more co-representatives dies, becomes disabled or is removed. In regard to co-executors, it is based on the assumption that the decedent would not consider the powers of fiduciaries to be personal, or to be suspended if one or more could not function. In regard to co-administrators in intestacy, it is based on the idea that the reason for appointing more than one ceases on the death or disability of either of them.
Massachusetts comment
See G.L. c. 195, § 11 to the same effect.
