Williams v Parris [2008] EWCA Civ 1147, [2008] All ER (D) 235 (Oct)
Once a finding of an express arrangement or agreement has been made, all that the claimant to a beneficial share under a constructive trust needs to show is that he has acted to his detriment or significantly altered his position in reliance on the agreement. It is not necessary to show that the arrangement or agreement involved the making of something in the nature of a bargain between the parties, and that the claimant has performed his part of that bargain.
