Drawing upon the history of the doctrine of the old use, Professor John Mee has suggested both that the extent of the authority for a “retention” approach to “automatic” resulting trusts has been overlooked, and that while as a matter of history a “retention” approach has significant support, as a matter of principle in the modern law it is not fully satisfactory, so that it is necessary to look elsewhere for a theoretical explanation for the “automatic” resulting trust. This article examines the reasons for the inconsistency identified by Professor Mee, seeking to elucidate the relationship between uses and trusts, to contribute to the history of resulting uses and trusts, and to explain why the modern “automatic” resulting trust has become a rule in search of a rationale.
