My ex husband is now over $2,000 behind in child support payments. I have taken him to court in Fairfax County (where the divorce decree was processed) multiple times now. He was found in contempt for not paying arrears in a timely manner and spent a week in jail until he was able to come up with the past due in full. I have been trying to work with him on his payments but he is still not up to date. He is now refusing to pay any child support because he is upset about a provision in the divorce decree regarding child tax credits. What recourse do I have to get the past due child support paid in full? We have three children and I am unable to afford daycare, etc. without his child support. Am I able to take him to court in Loudoun County since that is where we both now live?
