Regulation 28 Collection and refund of contributions
(1)
Where a client is required to make a contribution in respect of the cost of advice or assistance, the solicitor may collect that contribution in such instalments as may be agreed between him and the client and where the total contribution is likely to exceed the cost of giving advice or assistance, he shall not require the client to pay a sum higher than would be expected to defray his reasonable costs.
(2)
Where the reasonable costs of the advice or assistance are less than any contribution made by the client, the solicitor shall refund the balance.
