Where would i look to find if I am legally married?

You're married. Why do you ask? That's the real question.

None of the legal marriages performed were invalidated by the later-passed laws subsequently overturned by the Supreme Court's rulings last year. You can "check" for your marriage license/certificate at your county vital records office. Ms. Straus does have a good point though - are you asking because you are curious and weren't tracking the litigation, or is there a reason other than that? You will find no help here without a complete question and facts to support it.
