Legal Question in Family Law in California

Your question is a little confusing, you may try reposting this question with some more information if my answer is not helpful. Are you living with mom but want to live with dad now? Is mom willing to go along with this? What papers has he signed? If mom and dad agree, they still need to have a judge sign the papers to legally change custody (probably support too, but that isn't your problem, it is theirs). It can be as quick as the date set for hearing. Hopefully this will go smoothly for you. Good luck.
