124. No advocate and solicitor to sue for costs until delivery of bill of cost

Except as authorized by this Act, no advocate and solicitor shall without the leave of the court commence or maintain any action for the recovery of any costs due for any business done by him until the expiration of one month after he has delivered to the party to be charged therewith, or sent by post to, or left with him at, his office or place of business, dwelling house or last known place of abode, a bill of costs, which bill shall be signed either by the advocate and solicitor, or in the case of a partnership, by any of the partners, either with his own name or with the name or style of the partnership, or by another advocate and solicitor employed by the first-named advocate and solicitor or the partnership, or be enclosed in or accompanied by a letter, signed in the like manner, referring to the bill.

Where a bill is proved to have been delivered in compliance with subsection (1) it shall not be necessary in the first instance for the advocate and solicitor to prove the contents of the bill and it shall be presumed until the contrary is shown to be a bill bona fide complying with this Act.
