My boyfriend has been paying for 7yrs on child support and arrears, on his back child suport in Texas. His orginal back dept was put at $22,000. His daughters are now 21 and not going to school. He has been paying 500.00 not including his current child support at the time of judgement, a month on back child support for the last 7 years and each time we check on the balance he is told that he will be paying this for the rest of his life due to interest? We have figured he has paid 2x's the orginal amount of back child support arrears, Can someone please explain how this can be true? There must be a way to stop this or at least lower it?
