There was not any law of contract at all, as we now understand it. The two principal kinds of transaction requiring the exchange or acceptance of promises to be performed in the future were marriage and the payment of wergild. Apart from the general sanctions of the Church, and the king’s special authority where his peace had been declared, the only ways of adding any definite security to a promise were oath and giving of pledges. One or both of these were doubtless regularly used on solemn occasions like the settlement of a blood-feud; and we may guess that the oath, which at all events carried a spiritual sanction, was freely resorted to for various purposes. But business had hardly got beyond delivery against ready money between parties both present, and there was not much room for such confidence as that on which, for example, the existence of modern banking rests. How far the popular law took any notice of petty trading disputes, such as there were, we are not informed; it seems likely that for the most part they were left to be settled by special customs of traders, and possibly by special local tribunals in towns and markets. Merchants trafficking beyond seas, in any case, must have relied on the customs of their trade and order rather than the cumbrous formal justice of the time. Anglo-Saxon landholding has been much discussed, but is still imperfectly understood, and our knowledge of it, so far from throwing any light on the later law, depends largely on what can be inferred from Anglo-Norman sources. It is certain that there were a considerable number of independent free men holding land of various amounts down to the time of the Conquest. In the eastern counties some such holdings, undoubtedly free, were very small indeed.[57] But many of the lesser free men were in practical subjection to a lord who was entitled to receive dues and services from them; he got a share of their labour in tilling his land, rents in money and kind, and so forth. In short they were already in much the same position as those who were called villeins in the twelfth and thirteenth centuries. Also some poor free men seem to have hired themselves out to work for others from an early time.[58] We know next to nothing of the rules under which free men, whether of greater or lesser substance, held “folk-land,” that is, estates governed by the old customary law. Probably there was not much buying and selling of such land. There is no reason to suppose that alienation was easier than in other archaic societies, and some local customs found surviving long after the Conquest point to the conclusion that often the consent of the village as well as of the family was a necessary condition of a sale. Indeed it is not certain that folk-land, generally speaking, could be sold at all. There is equally no reason to think that ordinary free landholders could dispose of their land by will, or were in the habit of making wills for any purpose.
