If a parent does not have primary conservatorship or custody of a child, he or she will likely be required to pay child support to the other parent until the child turns 18 years old or graduates from high school, whichever is later. Many parents rely on child support from the other parent to provide the best possible lifestyle for their child.
In general, child support is calculated based on a percentage of the net income of the obligor-parent. Child support also varies depending on how many children are involved.
