(1) This rule applies to a proceeding (including a proceeding in the Court of Appeal) in which:
(a) money is claimed or recovered by or on behalf of, or adjudged, ordered, or agreed to be paid to or for the benefit of, a person under a disability; or
(b) money paid into court is accepted on behalf of a person under a disability.
(2) The costs of a proceeding to which this rule applies which are payable by a plaintiff to his solicitor shall, unless the Court otherwise orders, be taxed on the indemnity basis.
(3) On a taxation under subrule (2), the Taxing Master shall also tax the costs payable to that plaintiff in those proceedings and shall certify:
(a) the amount allowed on the taxation of the solicitor's bill to his own client;
(b) the amount allowed on the taxation of costs payable to that plaintiff in that proceeding;
(c) the amount (if any) by which the amount referred to in paragraph (a) exceeds the amount referred to in paragraph (b); and
(d) where necessary, the proportion of the amount of that excess payable by, or out of money belonging to, respectively, any claimant who is a person under a disability and any other party.
(4) Subrules (2) and (3) apply to and in relation to a proceeding in the Court of Appeal as if for a reference to the plaintiff there were substituted a reference to the party, whether appellant or respondent, who was the plaintiff in the proceeding which gave rise to the appeal proceeding.
(5) Nothing in this rule prejudices a solicitor's lien for costs.
(6) This rule also applies to and in relation to a counterclaim by or on behalf of a person under a disability as if for a reference to a plaintiff there were substituted a reference to a defendant.
