Collection of contributions and repayment of excess contributions
63.—(1) In fixing the method by which any contribution shall be paid by the client, the Director shall—
(a)require any contribution payable out of capital to be paid immediately if the sum is readily available or, if it is not, within such time as seems reasonable to the Director in all the circumstances; and
(b)require any contribution payable out of income to be paid by periodical payments at a rate which would, if the maximum contribution from income was required, secure that that maximum amount would be paid within the next ensuing twelve months.
(2) If the total contribution to the Department made by a client in respect of any proceedings is more than their liability to the Department under the Civil Legal Services (Statutory Charge) Regulations (Northern Ireland) 2015(1), the excess shall be repaid to the client.
