If there are no orders in place by the court, I would suggest you start there - if the parents are not able to come to a decision - mediation will be ordered by the courts. Hopefully in the near future you will both be able to work together in regards to caring for your children.
If you mean, the child's mother (ex-wife) has custody, the child's father (ex-husband) is obligated or potentially obligated for support.
He has two daughters with ex-wife Sara, and a son from his first ex-wife
yes
You can ask the court to do so, but you are not likely to be successful as long as your ex-wife has legal custody and your child has a hunting license.
No....
Yes of course if he has custody.
no unless he can not support the child
For your sake, I hope she's willing to repeat that story to the judge.
yes, if there was a support order in place during that periodANSWERBut, if it was not modified to match her reduction in income, you should mediate a reduction in the amount owed and register it with the court. check my profile for why
Your current wife is not responsible for your children by your ex-wife.
no
Well as long as you are the father, you are resposible for taking care of your child. And if your ex-wife is still responsible financially for the child then even though he is living with someone else then pay up!!
