Move to MA? All I know is that there, non custodial parents slide on child support all the time UNLESS the custodial parent goes on welfare. If s/he works, s/he's on her own. The state only goes after the child support if the custodial parent is on support from the state, so they can recover their costs.
My ex never went to jail, has never paid back support, or interest or anything else. Conservatively, I could easily pay off my house on what he owes, and that's without asking him to split college costs (I paid that completely out of pocket too)
More men should ask for custody - too often they say they can't manage full time child care with their jobs, etc. Although women do that all the time. Most guys don't ask for custody, and more should. Custody should go to the parent who is capable of providing the best home and atmosphere for the child, or custody should be joint if the parents can work together and agree to stay in the same area so the kids dont have to go back and forth to different schools.
