What a terribly sad situation. There's nothing you can do personally to force the issue. You can file an action against the father in court for failure to adhere to court ordered visitation and he may be found in contempt of court as a result (and fined/jailed as a result) but that would probably only embitter him further. Do you really want to expose your children to that kind of attitude?
The father will undoubtedly regret his actions later on, but in the interim, remain supportive to your children and think about some family counseling for you and your kids. It may help all of you cope with the circumstances.
The father does, since the mother is paying her share towards the children in the form of child support.
The parent would get support from the children's father--only while the children are in her custody as minors.
Yes. It is only fair that the mother has to pay child support. It is no different than if a woman and a man had separated and the mother was a single mother that he would have to pay child support. It is about the welfare of the children, not about who is taking care of the children.
Yes, you do.
The court may require the father to conduct a job search, which the court will supervise.
The father has the right to visit with his child unless the court issues an order to the opposite.
Yes, if the father is not given custody he will be obligated to keep paying support to whomever the court awards custody or guardianship of the children.
If he's paying child support yes.
Paternity must be established before support is established. Paternity may be established by the father's acknowledgment of paternity in open court.
No, the father has to pay child support for both children. Of course the child that decides to live with him will be treated as he/she were when you were both married, but the child you have will still continue to receive child support by law!
Nothing changes regarding child support orders whether it is the mother or the father who is remarrying. The child/children are the responsibility of the biological parents not a new spouse. For example if the mother marries someone of substantial means it would not affect the child support amount that was ordered to be paid by the biological father, as the mother's new spouse has no legal obligation to support the child/children.
You should pay through the court where child support was ordered. They will mail or otherwise get it to the mother in PA.
