48.4—(1) This rule applies where—
(a)a person is or has been a party to any proceedings in the capacity of trustee or personal representative; and
(b)rule 48.3 does not apply.
(2) The general rule is that he is entitled to the costs of those proceedings on the indemnity basis, so far as they are not recovered from or paid by any other person, out of the fund held by him as trustee or personal representative.
(3) The court may order otherwise but only if a trustee or personal representative has acted for a benefit other than that of the fund.
