PART 1. GENERAL PROVISIONS [18000 - 18420]

**( Part 1 added by Stats. 2004, Ch. 178, Sec. 10. )18200. *(a)*An agent designated by an unincorporated association for the service of process may file with the Secretary of State a signed and acknowledged written statement of resignation as agent of the unincorporated association.

I don't know how to prove it though.
