Used to work at a court house where marriage licenses were issued. Every now and then we'd have issues where people hadn't filled out the license correctly, gave faulty information, or more commonly, had a minister who wasn't authorized to perform a ceremony in our state. One time we had a cougar/boytoy type situation and it was very obvious that she was lying about her age. She gave us the wrong information, and swore to it, so the license was invalid. It worked out because about a week or 2 later, she returned wanting a divorce.
