What defines family law? Is it an area of law with clean boundaries and unified distinguishing characteristics, or an untidy grouping of disparate rules and doctrines? What values or principles should guide it – and how could it be improved? Indeed, even the scope of family law is contested. Whilst some law schools and textbooks separate family law from children’s law, this is invariably effected without asking what might be gained or lost from treating them together or separately. Should family law and children’s law be distinguished or treated together?
One would expect disagreement on these questions in any context. In bringing together theorists from multiple jurisdictions and at least two primary disciplines, we should not be surprised to find deep differences in approach reflecting different methodologies and foundational questions. The tension between them, we hope, can illuminate and enrich discussion on all sides. Further, through combining insights from law and philosophy, we also intend to add another layer to the current trend to focus on the empirical in family law research, and highlight how critical debates in children’s and family law are at once theoretical and empirical in nature. Understanding the nature and content of a child’s “best interests” as contained in multiple jurisdictions’ legal frameworks regulating private and/or public law concerning children, for example, requires us to approach the matter both conceptually – in order to adjudicate between frameworks – and in terms of fit with evidence from research. This immediately makes any satisfactory resolution more uncertain, contested, and subject to criticism. It is in this context that we hope that the conversations between law and philosophy, their points of agreement and divergence, can advance stalled debates.
International differences correspond, of course, to differences in law, policy, and procedure. Contrast, for example, England and Wales’ ‘single pot’ approach to the distribution of property and maintenance upon marriage breakdown to the more common, “pillarised” treatment of matrimonial property, pensions, and maintenance. The difference in system design necessarily affects the available potential justifications. As a more nuanced aspect of the impact of system design, one might consider the normative difficulties created by the variation in default regimes adopted in relation to matrimonial (or marital) property between US states. Facing jurisdictional differences – like considering historical changes within one’s own jurisdiction – can yield an awareness of the context-specificity of one’s own starting points. And awareness of how things are done differently can lead us to call into question our own ways of doing things. Such awareness might alert us to unintended consequences of legislation or to innovative solutions. And, more fundamentally, it might cause us to interrogate what we take as the core, the normal, or even the natural. This is where philosophical investigation becomes indispensable.
In Section II, we outline a number of respects in which the approaches taken by (academic) lawyers and philosophers writing in this field tend to differ, as well as how the structure of this collection seeks to cut across and highlight both these divergences and shared accounts. In Section III, we introduce the key themes that underpin the collection, which demonstrate the potential for cross-fertilisation between legal contexts as well as between legal and philosophical perspectives. When we refer to ‘lawyers’ and ‘philosophers’, we have in mind those working in family law and children’s law in particular.
