Child Custody of children to a father but never been married?

What rights does a father have if the mother of a child(ren) did illegal drugs and the children were taken away. Then a court order gave the children to the father and the mother could have no contact unless the father was present, and she has no custody, but this was only for 2 months. There was no child support filed and the only thing that proves he cares for them is the cps paper saying he is the sole caregiver for the 2 children. What can he do to take full custody of the children?

In order to be an official custodial parent of the children he needs to go to court and request a paternity test. If the results are clear that the children are his, He can then be the official custodial parent due to the fact that the children were taken away from the mother that is if he does not have a criminal record of any sort. He will be able to take his children from where they are living and then the mother needs to pay child support. Good Luck.
