Co-representatives; when joint action required.

A. If two or more persons are appointed co-representatives, the concurrence of all is required, unless the will provides otherwise, on all acts connected with the administration and distribution of the estate. This restriction does not apply when: (1) any co-representative receives and receipts for property due the estate; (2) the concurrence of all cannot readily be obtained in the time reasonably available for emergency action necessary to preserve the estate; or (3) a co-representative has been delegated to act for the others. B. Persons dealing with a co-representative, if actually unaware that another has been appointed to serve with him or if advised by the personal representative with whom they are dealing that he has authority to act alone for any of the reasons mentioned herein, are as fully protected as if the person with whom they dealt had been the sole personal representative. C. A co-representative who abdicates his responsibility to coadminister the estate by a blanket delegation breaches his duty to interested persons as provided by Section 3-703 [45-3-703 NMSA 1978].
