[3] Walter is known for his varied legal actions, at a time that the newly established Norman kings were taking lands from the nobility and ecclesiastical estates.
The court cases are part of a large collection of pleadings, at this time, against a process of Normanization that within a decade saw 64% of land in England consolidated into the hands of just 150 individuals, and many of the nobility deprived of their estates.
Walter appears to have been involved with the dispute between Urse d'Abetot, Sheriff of Worcestershire and the Bishops Wulfstan and Ealdred, of York.
Walter was a witness of a charter wherein Queen Matilda granted three hides at Garsdon in Wiltshire to Malmesbury Abbey.
[11] He was a witness to a charter of William the Conqueror that Bishop Wulfstan should "have fully his sake and soke, his services, and all the customs belonging to his hundreds of Oswaldslow".
