How does custody affect child support?
Your physical custody arrangement (sometimes known as a parenting schedule, parenting time, or residential schedule) affects who pays child support. Notably, this physical custody is different from legal custody, which involves parental decision making for the child's well-being. Depending on your physical custody arrangement, a parent may or may not need to pay child support.
For instance, if a child mainly resides with Parent A and only visits Parent B occasionally, Parent A has sole custody. In this case, Parent A incurs most of the costs of daily living and Parent B will likely pay child support.
If a child spends a fairly equal amount of time with each parent, child support may not be necessary. For example, the child might alternate between parents on a weekly basis. In this case, the parents have shared physical custody and likely contribute equally to the child's financial care.
Keep in mind that physical custody is just one factor in determining child support payments. Income and special expenses are other factors to consider.
