Paying Child Support If Spouse Withholds Parenting Time
Your obligation to pay child support is independent of your right to see your kids. If she is not letting you see your kids, you need to take her back to court. However, your child obligation does not cease just because you are not seeing your kids.
If your financial circumstances have changed (gotten worse) since the original child support order, you might be able to seek a modification. However, you need to pay her something every month. Failure to do so could land you in jail. At the very least she could get a judgment against you for past due child support which accrues interest at the rate of 12% per MONTH.
