I keep all of our important documents in one binder. I include things like birth certificates, diplomas, shot records, SS cards, etc. etc. I place each document in one of those plastic paper protector thingys. Then I make copies of each document and keep them behind the original which really saves me time if and when I need a copy of it.
We keep it in a safe place that both my husband and I know about. It is great if you ever have to leave in a hurry (which we have had to do a couple of times).
Works for me!
