During the thirteenth century, English lords acted to halt the deterioration of their feudal powers brought about by social and legal changes at the end of the twelfth century. Their determination produced a long line of legislation on feudal incidents, mortmain, and subinfeudation that stretched from Magna Carta to the Statute of Quia Emptores in 1290. Yet, until that legislation was finally in place, landlords had to find other methods of maintaining their lordship over free tenures. Professor Donald Sutherland, for example, has shown that lords asserted “a new authority to take into their hands the holdings of their free tenants if the tenants attempted to alienate the holdings in ways that prejudiced the lord's rights.” Lords also used conditional grants to restrict alienation, and beginning in the early thirteenth century, they played an important role in the effort to reassert tenurial lordship. Conditional grants have been studied primarily in the context of the family, which used them to create marriage portions, jointures, and entails. This study of a sampling of cartularies and charters, however, analyzes the different forms of restrictions on alienation in order to demonstrate how lords used the expanding remedies of the royal courts to reinforce their private lordship.

The right to consent to a tenant's alienation of his holding had been an essential prop of lordship prior to Henry II's legal reforms. Through his consent, the lord could determine the acceptability of his tenants and ensure the adequate performance of services attached to the holdings. He also protected himself against a serious loss of resources through grants in alms to the Church or through dowries to women marrying out of his lordship. Seizure of the tenement was the sanction that lords used to enforce their rights of consent. If a tenant failed to obtain that consent, he lost his land.
