Book excerpt: This collection provides a snapshot of big ideas in family law reform. The book asks: If you could change one part of family law, what would it be? This deceptively simple question is answered by 10 family law experts and debated within the volume by expert respondents. The book puts the proposal first, forcing authors (and their respondents) to critically engage with what family law should look like, and where the development of law is needed to address the changing landscape of family life. Globalisation, cultural and religious diversity, the use of technology and changes in societal attitudes towards marriage and parenthood have all had an impact on the continuing evolution of families. As a consequence, the law has some very complex challenges to address in its attempt to regulate the diversity of family life. This book is an invaluable resource for scholars of family law and serves as a pair to Hart Publishing's landmark Criminal Law Reform Now.
