(b) Any order entered contrary to subdivision (a) is void and without legal effect.

(c) For purposes of enabling a custodial parent receiving assistance under Chapter 2 (commencing with Section 11200) of Part 3 of Division 9 of the Welfare and Institutions Code to participate in a pilot project authorized by this chapter, the district attorney, upon the request of the custodial parent, may execute a limited waiver of the obligation of representation under Section 11475.1 of the Welfare and Institutions Code. These limited waivers shall be signed by both the district attorney and custodial parent and shall only permit the custodial parent to participate in the proceedings under this chapter.
