“The Child Support program responsibilities include locating parents, establishing paternity, establishing child and medical support orders, monitoring and enforcing compliance with child and medical support orders, reviewing and initiating modification of support orders, and distributing support collections.” — MDSS


If you are a non-custodial parent in Missouri, you are responsible for paying child support. The amount of child support you are required to pay is based on your income and the number of children you have. Child support guidelines are designed to ensure that children receive the financial support they need from both parents.

If you are unable or unwilling to pay the full amount of child support, you may be able to negotiate a payment plan with the other parent. You may also be able to modify your child support order if there has been a change in your circumstances. If you fail to pay child support, you may be subject to enforcement actions, including wage garnishment and seizure of assets.

Are Your Additional Expenses Being Managed?

Did you know that state systems only manage base child support payments & do not provide a way for parents to manage transactions & make payments for additional child expenses such as medical, education, child care or any other child-related expenses? Even if you have your base payments coming thru the state you need a solution to manage, track & pay all your child expenses – while providing a complete history & record.

SupportPay was built to help parents manage all child support & expenses while working with state payment systems.
