Maybe you could have him emancipated but my question is why? What is in the best interest of your son? If getting an education is then keep paying. Help him out as much as possible. Make it easy for him to get the education. Right now my ex is not forced to pay for college and my 19 year old may have to drop out because I can't afford to keep him there. I say pay as long as your kid needs it, regardless of the rules.
