Then yes, he will need to immediately file two things:
1. A Motion for temporary custody with the family court. In this motion, he will need to explain that he fears for the safety of his children due to their mother's drug use.
2. A Petition for custody (also filed with family court): In this he needs to list the children's names, birthdates, and social security numbers, explain that he is the father and is on the birth certificate. Explain that the mother is on drugs and that he is the fit and proper person to have permanent sole custody.
Once these are filed, a hearing will be held where the judge will issue a custody order.
He can either type these up himself and just explain everything or get an attorney to help him with this.
Please don't forget to ACCEPT so that I may be compensated for my time.
