 FitzWalter received livery of two-thirds of his inheritance, the remainder being held by his mother as her dower.This, says Starr, "represented a significant slice of the FitzWalter estate", and a wish to augment his wealth may have contributed to FitzWalter's later criminal behaviour.He encountered financial difficulty in London over lands which his grandfather, Robert, had transferred as fine land in 1275 to help found Blackfriars Abbey.
