We had a friend marry us and in our state (NH) you need to apply to the Department of Vital Records for a copy of the marriage certificate after your wedding license has been filled out and submitted by your Justice of the Peace and filed by the state. I suspect that if you hire an officiant they might automatically request a copy for you as part of the fee you pay them, but since we had a friend do it we currently have no legal proof that we are married.
I'm not changing my name, and we are keeping our own health insurance and everything, so I'm curious what we might actually need our physical marriage certificate for. I probably want to get a copy just so we have it, but additional certified copies cost less if you request them at the same time, so if they are necessary I might get them then.
Do we actually need a copy of our marriage certificate for any reason (other than sentimental/personal ones)?
In what situations would we need a certified copy, vs just a photocopy, of our marriage certificate?
