Can a repo company charge you for retrieving your personal property and property that belongs to someone else in the state of Kentucky?

Yes. Any property left in the vehicle when it was repossessed is additional property, not part of the repossession. As private property, the repossession company is liable to inventory the porperty and store it so that it may be recovered. State laws vary a bit, but the standard storage limit is thirty days. During this time they may assess a storage fee. You, the property owner must pay this fee to recover your property. Property that is not recovered in the time alloted by law may be discarded as the company sees fit.
