This collection explores the boundaries of trusts law in the Asia-Pacific region. It is uncontroversial to state that the region's jurisdictions are diverse, reflecting a mix of histories, economies, politics and legal systems. The essays in this collection illustrate how this diversity is reflected in trusts law. But this thematic and systematic exploration from a region-wide perspective also identifies patterns of commonality in those factors which limit the operation of trusts law, particularly as jurisdictions encounter domestic and international challenges. By charting both convergence and divergence, this study is pivotal in shaping and guiding the future development of trusts law in the region.
