A more thorough explanation:

The Doctrine of Worthier Title is a legal principle in real estate law that presumes that when a property owner transfers a future interest in the property to their own heirs, they actually intended to keep the interest for themselves.

For example, if a person owns a piece of land and wants to transfer ownership to their children after they die, but only after a certain amount of time has passed, the Doctrine of Worthier Title would presume that the person actually intended to keep the land for themselves until they died, and only then would it pass to their children.

This principle has been applied in various court cases, such as Estate of Grulke and Catawba Indian Tribe v. South Carolina. In Estate of Grulke, the court held that if a will gives the same estate to the beneficiary that they would have received if there was no will, then the beneficiary takes the "worthier title" by descent rather than under the will. Similarly, in Catawba Indian Tribe v. South Carolina, the court held that if a devise (transfer of property) is made to the heirs of the testator (property owner), but the interest given to them is the same as what they would have received by descent (inheritance) if there was no devise, then the devise is null and void.

It's important to note that many states have abolished the Doctrine of Worthier Title through legislation or court rulings. For example, the Code of Virginia has a section (§ 55.1-113) that specifically abolishes the doctrine.
