Yes, but you might consider filing charges against the mother for contributing, or for a change of custody.
No
A childs mother must file a petition for child support in the local family court.
Jessica's father was surprised to see his own daughter canoodling with her boyfriend in his bedroom.
You can, but eventually the court will question what you are doing.
It isn't the birth father, no one will ever change the childs birth father, but he will legally be the step father,until the divorce comes through.
Of course not. He is still the father of his children and still responsible for supporting them.
The parents of the deceased father (the childs grandparents) can do a paternity test.
No matter what she named the child the father is responsible for child support.
File for stop emotion
Uh, no, you cannot.
If he is the biological or adoptive father of your two children, yes, you can take him to court for child support. But if he is just your 'boyfriend' and has no other biological or legal relationship to your children, probably not.
What I would suggest is to not FORCE him to pay, but at least TRY to TALK HIM INTO IT.
