In enforcing the District's right to reimbursement, the Corporation Counsel may, on behalf of the District, do the following:
If the District separately institutes a proceeding against or settlement negotiations with a third party, the Corporation Counsel shall give the beneficiary, or if represented, the beneficiary's attorney, written notice of the action or settlement negotiations, by personal service or certified mail, within twenty (20) calendar days.
If a court proceeding has been instituted, proof of timely notice shall be filed with the court.
If the beneficiary has not instituted or proceeded to trial in a separate proceeding or executed a settlement agreement with the third party, the written notice served or mailed pursuant to § 1402.2 shall also advise the beneficiary of the beneficiary's right to intervene or join in the proceeding instituted by the District and of the beneficiary's right to retain private counsel.
