An heir presumptive is the person provisionally scheduled to inherit a throne, peerage, or other hereditary honor, but whose position can be displaced by the birth of an heir apparent or of a new heir presumptive with a better claim to the throne. When lowercased, "heir presumptive" can refer generally to someone who is provisionally scheduled to inherit a title, position or possession, unless displaced by an heir apparent or another heir presumptive. In both cases, the position is however subject to law and/or conventions that may alter who is entitled to be heir presumptive.
