We just recently had a will drawn up and we aren't sure where to keep it. I was looking into fireproof safes, but how do you know they're actually fireproof without setting it on fire and testing it out? And some of them are only good for half an hour, but if we were to die in a fire, I feel like it would probably be blazing for longer than half an hour.

Should we do a safety deposit box? Where does everyone else keep theirs?
