Some individuals do so with simply keeping a written log of such in a safety deposit box in a bank or at a trusted residence outside their home. Others will do about the same with photos and video. These are all great examples of how to protect yourself from a low ball bid from an Insurance Adjuster, or to keep the supplemental checks to a minimum.
