People who experience a property loss are usually asked by their insurance company for proof of purchase which can come in the form of a receipt or current inventory of their personal belongings.
Even the most organized people might find it challenging to find receipts for all the valuables in their home. If the inventory isn’t up-to-date, a homeowner might forget to add some items to the claim and may not recognize the omission for long after the claim is settled.
The inventory can serve as a guide to make sure a homeowner gets compensated for all the loss.
Photographs and videos can be adequate proof that the items belonged to the insured. A series of pictures of the different rooms, closets, cabinets and drawers are helpful. When video is used, consider commenting as it is shot and be sure to go slow enough and close enough to things becoming recorded.
Good places for your inventory could be a safety deposit box or digitally, in the cloud if you have server-based storage available like Dropbox.
