Okay, this may be a stupid question but we just got our official marriage certificate in the mail and I don't know what to do with it. I suppose I put it some place safe? Maybe make some photocopies of it? What important "life stuff" should I anticipate needing to present it for? For those of you who are already married, what did you do with yours? Have you had to use it for anything? FWIW, I'm not planning to change my name.
