Somner completed in 1647 a work on gavelkind. Relics of the old custom still remain in the case of gavelkind. It was more correctly described as socage tenure, subject to the custom of gavelkind. Partible inheritance ("gavelkind") prevailed in Kent, East Anglia and the Celtic areas. Under Brehon law, gavelkind, a form of partible inheritance, was the system of land inheritance. In terms of land inheritance it was a similar system to Gavelkind in ancient Ireland. Gavelkind was finally abolished by the Law of Property Act in 1925. Gavelkind was one of the most interesting examples of customary law in England. Gavelkind was the practice of partible or equal inheritance, as opposed to primogeniture.
