My ex-husband has been behind in child support. I no longer collect for my daughter (she's 20), but during the time he paid for her he got behind in a few payments ($1800). There is a court order but I have never used court collections. I was led to believe (by him) that when she turned 18 - payments could stop. He agreed to pay $100.00 a week until he got the $1800 taken care of - but never has. In addition, I discovered that he was to continue to pay until the child reaches 21 or is emancipated. My daughter began working full time in May of her 19th year. 7 months past her 18th birthday. I have calculated what he owes (including interest) and gave him that information last year... He was receiving some security funds and told me he would pay me from that.... well - you know the rest. My question is - is there a good payment calculator that I can use to find out what he truely owes me, and should I go back to family court to petition for arrears, or do I need a lawyer? Your comments are greatly appreciated!
