1. No costs attributable to the period during which a client was in receipt of ABWOR shall be recoverable from him until the court has determined the amount of his liability in accordance with section 12 of the Act:
Provided that where the ABWOR does not relate to or has been withdrawn so that it no longer relates to the whole of the proceedings the court shall nevertheless make a determination in respect of that part of the proceedings to which the approval of ABWOR relates.
