How do I go about getting my name changed. We were married on 4/20, but I've been so busy with school and final exams that I didn't have time to take care of it. I've heard that you need a certified copy of your marriage certificate. About 5 days after we got married we received our official marriage certificates in the mail (we already had the keepsake one.) Aren't these certified? There is some sort of seal on it like a notary seal.
