3. Inventory Your Possessions. The I.I.I. has information on how to conduct a home inventory, as well as software and mobile apps to make it easy and efficient. These free tools give you secure online storage so you can access the information anywhere, any time in the event of a disaster. If you have to file an insurance claim, having an inventory helps the process go smoothly as you already have a record of items, purchase prices, dates, serial numbers and receipts.
