Which document is typically NOT used as proof of ownership?

The certified farmer's certificate is issued to verify that an individual or business meets certain criteria to sell agricultural products, which pertains to the regulatory or licensing aspect of farming rather than directly confirming ownership of goods or assets.

The bill of sale is a key legal document that provides evidence of the transfer of ownership from seller to buyer for a specific item. Similarly, bills of lading serve as a contract between the shipper and carrier and play a role in establishing ownership during transport. Both documents are firmly rooted in confirming ownership in a transaction.

An inspection report, while useful in assessing the condition or quality of an item, does not serve the purpose of proving ownership. It focuses more on compliance and safety standards rather than establishing who holds legal rights over the commodity. Thus, of all the documents listed, an inspection report is least associated with the proof of ownership.
