Insurance companies require "proof of loss" before settling a claim. If you have an up-to-date inventory - you will have that proof.

Be prepared for Hurricane season and other disasters - create a detailed asset inventory list and a "walk through video" of the home or business, and digital photographs of your home or business property and individual contents.  You can also scan receipts, insurance information, and other important documents for transfer to digital medium for safe storage.

A good idea would be to store this information in a safety deposit box.
