If a 16 year old is emancipated is she able to date over the age of 18?

Do you mean that if a 16 year old is emancipated can she date a 18 year old? I suppose she can, but you have to realize that emancipation is much more than dating. To be emancipated means you are responsible for your living expenses, and how you live. You have to pay for yourself and are responsible for your actions. Your parents no longer have to take care of you.
