If one parent has sole custody, the other parent will likely be required to pay child support based on his or her adjusted gross income and other factors. If the parents have joint custody, the parent who spends – or is allowed to spend – more time with the child is usually the recipient of child support payments. If parents have joint custody and make about the same amount of money & have equal parenting time, then it is unlikely any child support will be ordered.
The time each parent spends with the child (as determined by custody and visitation arrangements) will also be a payment factor.
If a parent's economic or personal circumstances change significantly, it is possible for that parent to seek a child support modification. For such a change to occur, either or both parents must agree to change the support amount or the divorce court must enter a judgment.
A parent's obligation to pay child support can be terminated when the child turns 18, if the other parent remarries and his/her new spouse agrees to adopt the child, or it can be proved the parent paying child support is not actually related to the child. We can petition the court to require a simple DNA test that can prove or disprove whether a man is father to a child.
