(a) Whenever an administrator who has caused registered land to be transferred into his name stands ready to be discharged, if it is not necessary to sell such registered land for the purposes of administration and it should properly go to the heirs at law of the decedent, such administrator may institute a proceeding substantially similar to that prescribed in Code Section 44-2-131 for the ascertainment of the heirs at law and for an order directing the transfer of such estate from him to such heirs.

(b) If a trustee holds title to registered land and the beneficiaries of the trust are not definitely and particularly disclosed, if it becomes appropriate that they be definitely ascertained, such trustee may in like manner petition the court, upon showing that the trust has become executed, for a decree settling and ascertaining who the beneficiaries are and directing a transfer to such beneficiaries.
