The Soane Museum contains a number of papers and drawings that give an insight into property disputes during the closing years of the eighteenth century and the opening years of the nineteenth. This paper discusses two cases to illustrate some of the factors that brought about differences between parties. John Soane was sometimes called upon to act as an arbitrator to resolve disputes relating to matters such as poor construction, building prices and fee disputes between architects and their clients. The Soane papers are of more interest to the architectural than to the legal historian for Soane’s conduct of Hearings and submissions is less well recorded than are the snippets of information about architects and their schemes. It is rare to find Soane’s Award or decision.
