[B]y lavv no inheritance can veſt, nor can any perſon be the actual complete heir of another, till the anceſtor is previouſly dead. Nemo eſt haeres viventis [No one is the heir of the living]. Before that time the perſon vvho is next in the line of ſucceſſion is called an heir apparent, or heir preſumptive.

The perſon in this ſituation [having a mere right of property without possession or the right of possession of the property] may have the true ultimate property of the lands in himſelf: but by the intervention of certain circumſtances, either by his ovvn negligence, the ſolemn act of his anceſtor, or the determination of a court of juſtice, the preſumptive evidence of that right is ſtrongly in favour of his antagoniſt; vvho has thereby obtained the abſolute right of poſſeſſion.
