Justipedia explains Warehouseman's Lien
The possession of a customer’s property doesn’t simply mean that the warehouse operator can use the property or has the warehouseman’s lien. In fact, the warehouse operator must possess the customer warehouse receipt, which may serve as the warehouseman’s lien if it has information regarding the location of the warehouse and of the goods stored, handling charges or storage rate, etc.
