A claim may be allowed only if:

The damage or loss was not caused wholly or partly by the negligent or wrongful act of the claimant, the claimant's agent, private employee, or family member (the standard to be applied is that of reasonable care under the circumstances);

The possession of the property lost or damaged and the quantity is determined to have been reasonable, useful, or proper under the circumstances; and

The claim is substantiated by proper and convincing evidence.

Claims which are otherwise allowable under this subpart shall not be disallowed solely because the property was not in the possession of the claimant at the time of the damage or loss, or solely because the claimant was not the legal owner of the property for which the claim is made. For example, borrowed property may be the subject of a claim.
