A child support worksheet can help a non-custodial parent receive a rough estimate of how much their child support payments will be. Typically, the worksheet will include questions such as how much money the non-custodial parent gets paid from his or her job, how many children are involved, whether the non-custodial parent is currently making other court-ordered child support payments and more. Different states have different rules and guidelines for the amount of child support they must pay. While a child support worksheet may be helpful, individuals should speak to a child support attorney in order to determine exactly how much they are likely to be ordered to pay by a court of law. A child support attorney can also help the non-custodial parent fight for his or her visitation rights and seek child support modification if certain situations have changed since the original child support order was put into effect. A child support attorney can be a valuable resource for both custodial and non-custodial parents.
