If your child support is court ordered and if you are having it pulled from paychecks, the State will catch him in arrears. If you don’t have it withdrawn by the state (via his check), then you must issue a ‘show cause’ and go to court. I don’t think there is a way around that part.
As far as your credit. In MY case, I didn’t trust my ex to pay ANYTHING in both of our names, so I got the credit card debt and we negotiated a ‘fair exchange’ for that debt…I got the house free and clear. I didn’t have to buy him out. He was ALSO 12k in arrears for child support, so I had to go to court to get it automatically taken out of his check. In NC, once you have that done, the state keeps tabs on the Payor. I have been very pleased with that system and have had no problems. HE hates it, but his refusal to pay in the past was what prompted me to do this. He had MANY chances to do it right, and he chose other expenses were more important.
If you want to keep your credit good (or rebuild your credit) you’re going to have to take that debt. You can’t squeeze blood from a turnip…and he’s making himself be a turnip. I’m sorry [:(]
