a person who expects to inherit but whose right can be defeated by the birth of a nearer relative

An heir presumptive or heiress presumptive is the person currently entitled to inherit a throne, peerage, or other hereditary honour, but whose position can be displaced (in legal terms, is "subject to divestiture") by the birth of an heir or heiress apparent or of a new heir presumptive with a better claim to the position in question. The position is however subject to law and/or conventions that may alter who is entitled to be heir presumptive.
