If you live in the US... There are no laws regarding dating in any state. There are laws regarding sexual contact with minors (which are not limited merely to intercourse), but they are two different things. However, the parents of a minor have the right to determine who their child is and isn't allowed to spend time with. If the parents of the minor give permission for them to date, they can. If the parents say 'no', then they can't.
