Primer Seisin

Primer seisin, a feudal burthen, only incident to the King's tenants in capite, and not to those who held of inferior or mesne lords. It was a right which the King had, when any of his tenants in capite died seised of a knight's fee, to receive of the heir (provided he were of full age) one whole year's profits of the lands, if they were in immediate possession; and half a year's profits, if they were in reversion, expectant on an estate for life. It was incident to socage-tenants in capite, as well as those who held by knight-service. It was abolished by 12 Car. 2, c. 24.
