Interest on debts
18.—(1) Where an account of the debts of a deceased person is directed by any judgment, then, unless the deceased's estate is insolvent or the Court otherwise orders, interest shall be allowed—
(a)on any such debt as carries interest, at the rate it carries, and
(b)on any other debt, from the date of the judgment at the rate payable on judgment debts at that date.
(2) A creditor who has established his debt in proceedings under the judgment and whose debt does not carry interest shall be entitled to interest on his debt in accordance with paragraph (1)(b) out of any assets which may remain after satisfying the costs of the cause or matter, the debts which have been established and the interest on such of those debts as by law carry interest.
(3) For the purposes of this rule “debt” includes funeral, testamentary or administration expenses and, in relation to expenses incurred after the judgment, for the reference in paragraph (1)(b) to the date of the judgment there shall be substituted a reference to the date when the expenses became payable.
