The department reviews more than 1,200 Third Party Petitions each year. The directions for filing are clearly set forth on the form: it is to be sent to the department's central scheduling unit along with a copy of the contingent fee agreement, a substantiation of all expenses claimed, four copies plus an original, and a self-addressed envelope of sufficient size and postage so the department can return the four approved sets to the sender for distribution. Attorneys who follow the filing instructions and answer the questions posed on the petitions find this a rewarding niche area of workers' compensation practice.
