How to get Full custody of my son ?

You can talk to the local courthouse about taking full custody because he is doing illegal activity and your afraid he might do it around your son. They will send him a letter in the mail telling him when to show up to court. But in the meantime it might cost you some extra money, i know filling out the paper work just to take him to court can cost up to $250. and if you get a lawyer that could cost up to $4,000. If you do get full custody he will have to pay child support every month. Good luck
