It depends on where you live. In the United States, the parent who filed for child support can file for modification or termination of child support, but needs to provide supporting documentation as well as good reasons why it should be modified/terminated. The court looks at the well being of the child and what would be best for him/her, not whether a parent has a change of heart and is doing this to cut the other parent some slack.
no
If the child is not with them at all, the child support should go to the one who have custody of the child. If they share custody they have to agree on who will pay support and who will take the responsibility and see to that the child have everything he needs. If the parents can not agree the court will decide.
The parents can agree to waive the unpaid support - the court must approve this after finding it to be in the child's best interest.
By law, child support belongs to the child. Therefore, parents cannot agree between themselves to waive or reduce child support, either past-due or current. The venue that issued the order must approve any such agreement.
If the parents can't agree the court will decide for you.
The child support must be paid to the custodial parent unless the parents agree otherwise and the child support order is modified by the court.
Most countries do allow an agreement to be written up between parents detailing their own child support amounts. Please be aware that this should be legally done and shown to child support so that it is not held against someone in the case of your relationship turning sour.
Generally, both parents. Child support is based on actual time spent with the child and actual money earned by each of the parents. You need to go the Child Support Services in your city/county to file for child support. There will be a short hearing - unless both parties agree - and a judge will determine who pays and how much.
yes, as long as the parents agree to allow their child to live with their grandparents its fine as long as the grandparents can support the child.
The parents of a ward of the state will not receive any child support. They were determined to be unfit parents, and do not have a child to support.
Not until the arrearages for the support are paid.
The child can not decide this on their own until they are 18. And yes, you owe money and they have to be paid. If both parents agree and let the child move, the former custodial parent have to pay child support to you.
