A more thorough explanation:

A bill of adventure is a legal document used in maritime law. It is a written statement by a shipper that the property being shipped belongs to someone else and is being transported at the owner's risk.

For example, if a company is shipping goods from one country to another, they may use a bill of adventure to indicate that the goods belong to a different company and that the risk of loss or damage during transportation is the responsibility of the owner.

Another example could be a person shipping their personal belongings overseas. They may use a bill of adventure to indicate that the items belong to them and that they are aware of the risks involved in shipping their belongings.

The purpose of a bill of adventure is to protect both the shipper and the carrier by clearly stating who owns the property being shipped and who is responsible for any loss or damage that may occur during transportation.
