[10] Which may be translated as:[11][12] At his father's death in 1269 Walter inherited his family's part of the manor of Powick in Worcestershire, where he made his seat at Beauchamp Court, on the right bank of the River Severn.
The estate had been inherited, together with Elmley Castle and other lands, by Walter's three-times great-grandfather Walter I de Beauchamp (d. 1130/1133), founder of the Beauchamp family, on his marriage to Emmeline d'Abitot, daughter and heiress of Urse d'Abitot, Sheriff of Worcestershire.
[citation needed] In about 1263 he acquired a moiety of the manor of Alcester in Warwickshire which he held from Reynold FitzPeter by the tenure of "doing the foreign service of ½ knight's fee".
Around 1274, he confirmed to his free burgesses and tenants their ancient right to hold a weekly market on a Tuesday, and also granted them a weekly market on a Thursday, allowing the sale of animals, flesh, wheat, rye, barley, oats, beans, pease, woollen and linen drapery, bread, iron goods, tallow, grease, fish, leather goods, baskets, hides, wool, linen, geese, hens, cheese, bacon, eggs, salt and spices.
[18] Unbeknownst to themselves they were found to be within the fourth degree of consanguinity, which necessitated a ratification of the marriage by Godfrey Giffard, Bishop of Worcester to legitimise their issue.
