(a) (1) If there is a formal administration of an estate, the court with jurisdiction to administer the estate shall determine, for purposes of the inheritance tax, the value of any concurrent absolute interest or less than absolute interest in property that passes from the decedent, that is listed in an account required under § 7-305 of the Estates and Trusts Article, and that is not valued in the manner required in §§ 7-209 through 7-211 of this subtitle.
(2) If the court approves an account required under § 7-305 of the Estates and Trusts Article, in which a concurrent absolute interest or less than absolute interest is valued:
(i) approval of the account is deemed to be court determination of the value of the concurrent absolute or less than absolute interest, for purposes of the inheritance tax; and
(ii) a separate petition to the court or a separate judicial order is not needed to value the concurrent absolute interest or the less than absolute interest.
(b) If there is no formal administration of the estate, the register in the county where the inventory is filed shall determine, for purposes of the inheritance tax, any concurrent absolute interest or less than absolute interest in property that passes from a decedent.
