I assume that you mean "from the biologicalfather". The father have every right to have you see his child when the child stays with him. The mother can do nothing about that unless she can prove you are unfit or dangerous to the child and then she will need a court order to keep you away.
The court's duty is to make decisions for the best interest of the child. If the Doc has recommended it and the court finds it in line, the child stays with the mother.
Child support is paid until the children are 18.
