[For a comparative perception, it's worth reading S. D. White, 'The discourse of inheritance in twelfth-century France: alternative models of the fief in Raoul de Cambrai', ibid., 173-97].
The disagreement over inheritance, heritability and 'inheritance language' (Hudson) is so profound and complex that it will not be possible here to do more than suggest major points of comparative debate. The tide has tended to be against Milsom on most fronts, at least in published work, but most still acknowledge the depth of his thinking about these questions. Perhaps White's essay is closer to Milsom than the other recent writings, presenting a more nuanced picture. Disagreement with Milsom has tended to form on two fronts:
Milsom re-created the 12th century principally from study of the plea rolls and the assizes in a retrospective way; references to charters in his work can be found, but are sparse. Basically, he relied on Stenton, the foundation of whose work was a quite intimate study of charters. Recent revision of Milsom/Stenton, such as Hudson's, has investigated the charter material again in extenso.
Milsom's basic premise was that, before the impact of the assizes of Henry II, inheritance was deferred. Discretionary lordship meant that the 'heir' had only an expectation of succession, a promise by the 'good' lord to his tenant about the future of the fee.
The debate thus centres on the interpretation of succession de facto, which most acknowledge: did succession de facto equate with the principle of heritability, suggested by Holt et al., or was it simply de facto succession?
Milsom's proposals may be illustrated by two quotations:
The core of the matter is then the meaning of words purporting inheritance in charters, which occur in grants to lay tenants from the 1130s: sibi et heredibus suis; iure hereditario; hereditarie; hereditabiliter; in feudo et hereditate -- promise, expectation or rule? More particularly, what is the significance of grants to a tenant and one heir (sibi et heredi suo) which occurred in charters in the early 12th century? What too should we make of those early charters which are silent as to the nature of tenure? Finally, it should be noted that Tabuteau maintains that language of inheritance was common in Norman charters before the Conquest.
Some charters (even into the 1170s), when an heir succeeded, were confirmation charters issued by lords to acknowledge that inheritance/succession. In many cases, the verb reddere was employed -- what is its significance? Does a succession require the consent of the lord or is this merely a convention?
Hudson makes much of events on the estates of the religious, where, although canon law prohibited alienation and a grant in fee and inheritance was tantamount to alienation, fees became hereditary in the early 12th century. He suggests that this paradigm, the tendency to heritability on the lands of the Church, suggests heritability more widely. Perhaps the following questions may be raised:
