Frankly, I'm surprised CSE hasn't already done a review of your case if it's been 7 years. I realize they get very backlogged, but to think a case can sit for 7 years is a little scary. Anyway, I just wanted to say that everyone's got there own opinions here (and bitter experiences are prevelant in several posts on this thread here), but my advice would be to call CSE and request a review. They will not disclose to him that it's you who's requesting the review. At that time, everything can be re-evaluated, including his income, setting an amount toward the arrears, etc. (I wouldn't let those go either. This is money he was responsible for paying for his kids. You were just nice in not enforcing the order for a year.) One thing to keep in mind is you don't necessarily have to go before a judge. You can always "propose" an amount that you think is fair and acceptable and see if he'll agree to it. Another thing to keep in mind is are you going to get true and correct information from him as far as what he's earning now? If he's working for family, will they lie about his salary?
