<prompt> Human: We got married over a year ago. Basically, we lost the marriage certificate so they would let us change her name with just the license. So weve been putting off for over a year. Can we still file jointlymarried if my last name is different than hers?EDIT: We are in Ohio btw.  <response>: Of course. There is no legal reason whatsoever either if you has to change your name.
