In NJ responsible for your 18 year old?
Probably. Generally, parents are responsible for the welfare of their children until these children reach the age of majority (usually 18) or are legally emancipated. Although in most states, children are emancipated by operation of law when they get married, the same is not true when these children have children of their own outside of wedlock. If you would like more information, I suggest that you should consult a lawyer. Good luck.
