Louisiana Revised Statutes Tit. 9, § 2432. Apportionment of tax liability among persons interested in estate

A. If the deceased has made no provision in his testament for the apportionment of the tax among the persons interested in the estate, the tax shall be apportioned among them by the court in the proportion that the value of the interest of each person interested in the estate bears to the total value of the interests of all persons interested in the estate. The values used in determining the tax shall be used for this purpose.

B. If the deceased has provided in his testament for the apportionment of the tax among all the persons interested in the estate, the court shall apportion the tax as directed by the deceased.

C. If the deceased has provided in his testament for the apportionment of the tax of some, but not of all the persons interested in the estate, the amount of the tax which has not been apportioned shall be apportioned by the court among those as to whom no provision has been made, in the same manner as is provided in Subsection A of this Section.
