I'm going to take a stab here, since I have some familiarity with these issues....

Rusty, here's the thing - DOFD isn't going to matter much here if you're thinking that CRTP is going to eventually cause this to disappear. Child support will not drop off the same way a revolving account will. Generally speaking, support orders are written for a certain amount to be paid each month. Even if the 2001-era stuff drops, if you are behind in any month in the last seven years, the debt can show up on your credit report. Think of it as a series of monthly debts - this is why child support can be so "sticky".

Mom couldn't have closed anything out, so I think you might have some misinformation happening there. I am guessing that the state's CSEA agency is enforcing the court order on Mom's behalf?
