My husband and I have a fireproof safe hidden in our house that has all our important documents. If there were ever a fire or another disaster. Grabbing just one item would save us a whole lot of trouble.
Consolidate your important documents (marriage licenses, birth certificates, SSA cards) and put them into a safe, or easy to grab and carry plastic box with a lid and a handle. The Container Store carries some stylish document boxes.
Other information such as credit card information, tax information and bill payments are most likely stored in accounts online. So these are not so much of a worry. Think mostly about the items that would be hard to replace if destroyed.
