So my question is if i agree to drug testing (urinalysis) in a child custody case do i have to take a hair follicle test just because my ex wants one done but it wasnt court ordered for me to do one???

You would probably have to abide by what the Court Orders! Aren't you the "mother" on the birth certificate? If they are suggesting you attend drug classes &/or testing, you abide by what they rule! It's up to the Court about hair follicle testing, NOT what the "absent father" suggests! Have his tested??? Do what they say w/bells on. You probably have the ONE CHANCE of keeping your children!! Walk the path of the straight & narrow! You can do it! Good luck...

I suggest contacting the Family Law Division to best answer your questions. https://www.kern.courts.ca.gov/divisions/family_law/contact_information
