Personal computers have been around long enough that everyone has experienced or knows someone who has lost their data due to a hard drive crash, accident or burglary. If they had a backup, the loss was inconvenient but not critical.
Do you have a backup for your personal belongings? Not that you need duplicates of all the items but do you have a journal listing of all the items with a description and their approximate values? That record becomes the backup that supports the claim for your insurance.
If a building sustains a total loss, the insurance company will usually pay the face amount of the policy. When it comes to personal property which might be 40% to 50% of the insured value of the dwelling, the insurance company is going to expect an accounting with receipts or at least, a relatively recent inventory.
The better your inventory, the less likely you'll have difficulty with the claim. Almost everyone has a digital camera that can take stills and probably even videos. The combination of the images as well as a written description will help you replace the belongings and serve as proof to the insurance company.
Once you've made the inventory, store it off site for safe keeping. Online storage in the "cloud" might be the best place to insure you'll always know where it is. Contact me for a free Home Inventory form; it's my way of helping you be a better homeowner.
