How to enforce a child support order
Contact the non-custodial parent.
If the parent has stopped paying child support, you should first try to determine why. Not every stoppage in child support payments is a willful attempt to deprive a child of funds.

Choose your answer from:
[a]. Instead, the other parent may have lost a job, been demoted, or suffered an unexpected medical emergency. You may not be on good terms with the other parent.
[b]. For example, a parent might simply not be able to pay child support if the child is absent for a long period of time or is on odd hours. In that case, contact the non-custodial parent and ask whether they can stop making any child support payments on your behalf.
[c]. Find the forms by visiting the legal and financial website of the federal department of child services (ssa). Click on the " find forms and instructions " link at the top right corner of the website.
[d]. Otherwise, you might want to do some investigating. Someone else, though probably not the custodial parent of a child, could accidentally withhold a child's money due to improper circumstances if they need to pay child support.
The answer is:
[a].
