Can I discontinue child support of my 19 year old moves out.

If your 19 year old is working full time or otherwise financially independent, married, or in the military, you can go to court and make a motion for a reduction in child support based upon her being emancipated. However, if she is still financially dependent on her custodial parent, you're obliged to pay until she's at least 21 or as per any child support agreement you signed that sets out the circumstances under which your children are considered emancipated for purposes of child support obligations.
