Heirs Apparent

Heirs Apparent

An heir apparent or heiress apparent is a person who is first in line of succession and cannot be displaced from inheriting, except by a change in the rules of succession.

An heir presumptive or heiress presumptive, by contrast, is someone who is first in line to inherit a title but whose claim can be displaced at any time (in legal terms, is "subject to divestiture") upon the occurrence of one or more events or sets of events for which the system of inheritance allows, such as the birth of a more eligible heir.

Today these terms most commonly describe heirs to hereditary titles, particularly monarchies. They are also used metaphorically to indicate an "anointed" successor to any position of power, e.g., a political or corporate leader.

The phrase is only occasionally found used as a title, where it usually is capitalized ("Heir Apparent"). Most monarchies give (or gave) the heir apparent the title of Crown Prince or a more specific title, such as Prince of Orange in the Netherlands, Prince of Asturias in Spain, or Prince of Wales in the United Kingdom. See crown prince for more examples.

This article primarily describes the term heir apparent in a hereditary system regulated by laws of primogeniture—as opposed to cases where a monarch has a say in naming the heir.
