A: Is the Court Order which set child support issued from a South Carolina court? If so, and you and the child are still in S.C., then the court retains jurisdiction. You should file a Rule to Show Cause against her (don't wait for the clerk of Court to do it), and part of the relief you request is that she pays through the Clerk of Court's office. By doing so, she MUST pay through the court or she will not get credit for it. I strongly urge you to get an attorney who can make the appropriate arguments for you.
