Based on North Carolina Law and Florida Law, if you can prove beyond a reasonable doubt that you have 50% custody awarded to either spouse, child support will be shared by both parents and in the event of tax time either spouse can claim the child as a dependent upon agreement through the court or the IRS will fine one of you for the deduction
Even sole custody fathers can be ordered to pay. see links
That is dependent on several factors, including difference in incomes. see links below
Reference to "seventy four percent" is unclear, but it seems unlikely that the child's mother could collect current child support in such a situation. (She can still collect past-due support, if any.)
If the mother has the full custody then she can take the child, and she can get the child support. If she doesn't have the full custody, then she is not allowed to take the child without the father consent, but she still can get the child support.
Yes.
Of course. If she has physical custody and your child is still your child then you must pay child support until your child support order has been modified by the court. A new spouse is not respondible for supporting non-biological children.
yes
You can't, they are still owed. Are you getting child support now? see link
Usually only the fathers
YES, a woman can file for child support and not address custody in the courts, but a man can not request visitation time without the subject of child support being addressed. All single mother have sole custody by default, in 49 states.
Yes, if the child is still a minor or is no longer a minor but is severely handicapped.
No, if the mother voluntarily gives cutody to someone else, she can no longer be paid child support because she no longer has custody of the child. What happens now is the father can obtain custody because he does have rights or the person who has custody and have legal guardianship can file for assistance in which child support can be included or filed.
Yes, if he has physical custody of your child.
The child support goes to the one who have custody. If the grandparent still do and the child has just moved out temporarily, they will still get it. If the child is under 18 and has moved they also still get it unless the child is emancipated. If the child is 18 the child support generally end but it depends on the state laws and/or what you have written in the child support agreement.
