My ex is once again in arrears. I have taken him to court about this several times before and nothing happes. He pays the state min so my kids or I am in no way suffering without his money. He has nothing to do with my kids and I would prefer it this way. I know if I file for collection of arrears again he is going to file something else in retaliation (either support or family) and I don't want to go through all this bull again. My question is how long can I wait to take him to court for arrears before I will no longer be able to collect? Best case I would like to wait until the children are 18 (they are 7 now) that way it will have added up and I can give it directly to them to help with college. Would anything regarding collection of arrears change if dad was on public assistance?
