During the vigor of the feudal law, a fine for alienation was a sum of money which a tenant by knight’s service paid to his lord for permission to alienate his right in the estate he held, to another, and by that means to substitute a new tenant for himself. 2 Bl. Com. 71, But when the tenant held land of the king, in capite, by socage tenure, he was bound to pay such a fine, as well as in the case of knight service. 2 Bl. Com. 89. These fines are now abolished. In France, a similar demand from the tenant, made by the lord when the former alienated his estate, was called lods et vente. This imposition was abolished, with nearly every feudal right, by the French revolution.
