A more thorough explanation:

A dead corporation is a corporation that has been dissolved. This means that it no longer exists as a legal entity and cannot conduct business or enter into contracts.

Dead freight refers to cargo space on a ship that is not being used. This can happen when a shipper overestimates the amount of cargo they need to transport, or when there is a delay in loading or unloading the cargo. The shipper may still have to pay for the unused space, which is known as dead freight.

Deadhand control is a legal concept that allows a person to control their wealth even after they have died. This can be done through the use of legal instruments such as conditional gifts, contingent future interests, and trusts. The goal is often to ensure that property remains in the hands of a particular family or organization. However, the rule against perpetuities limits the amount of time that deadhand control can be exercised.

For example, a wealthy individual may create a trust that specifies that their assets can only be used for the benefit of their descendants for a certain number of years after their death. This ensures that the wealth stays within the family for a set period of time.
