Child support calculation is the process of determining how much child support should be paid to the custodial parents by the non-custodial parent. Calculation is typically done by the judge, who takes into account the laws and limits in the particular state the family resides in. the judge will also consider how much money the non-custodial parent makes, as well as how many children are involved in the case. The judge may also determine whether the non-custodial parent is already making court-ordered child support payments to any other custodial parents. When all of this information has been factored in, the judge will perform a child support calculation that will become the court-ordered amount that the non-custodial parent will have to pay the custodial parent for the care of the children. A non-custodial parent should consider contacting a child support attorney before attending court so that the attorney can make it known what the non-custodial parent is able to pay, as well as fight for the visitation rights of the non-custodial parent. A child support attorney can be a very valuable help for a non-custodial parent.
