Groningen. I hope I have done justice to the valuable comments provided on earlier drafts of this essay by my colleagues in the Department of Private Law at UCT, the Progressive Property Law group's gathering in Boston, in 2014, Prof Pieter Badenhorst and the Masterclass participants of the Young Property Lawyers' Forum of 2012. Richard Cramer, Iain Shipley and Janine Howard rendered much appreciated research assistance. The financial support of the National Research Foundation and the Africa Knowledge Project of the Programme for the Enhancement of Research Capacity at the University of Cape Town is gratefully acknowledged. Opinion and remaining errors are my own and should not be attributed to these institutions.
