Heir general, or heir at law, he who after the death of his ancestor has, by law, the right to the inheritance.
Heir presumptive, one who is next in succession, but whose right is defeasible by the birth of a nearer heir, e.g. a brother or nephew, whose presumptive right may be destroyed by the birth of a child, or a daughter, whose right may be defeated by the birth of a son.

No person can be "heir" or "coheir" of another person until the latter is dead, though he or she may be heir-apparent or heir-presumptive.

A person benefiting under a will is a legatee of money, or a devisee of land, and not an heir to either.
