Where to start... First, you don't have to have a lawyer to collect back child support. Your local Child Support Office should be doing this for you. In my case, my ex owed my two daughters more than $27,000 in back support. I followed him more than 13 years thru 4 states trying to collect. I never gave up or stopped pushing the Child Support Office to do their job. My daughters are now 20 and 21. I started collecting the arrears about 2 years ago. I went to a hearing where another woman was trying to collect support and the judge helped me have my case looked at again by the District Attorney. I will be collecting checks for years, as long as he doesn't move again.
Just know that there is always hope. Stay in contact with your local Child Support Office at least once a month. Never give up. It is not easy, but I know it can be done because I have 2 beautiful daughters that are wonderful.
Good luck.
