Customary law
Customary law: binding community practices recognized as legal norms.
Last updated
Customary law, also known as consuetudinary or unofficial law, refers to established patterns of behavior within a social setting that are considered legally binding. It exists where a certain legal practice is observed and relevant actors consider it an opinion of law or necessity (opinio juris). Most customary laws deal with long-established community standards, but the term also applies to areas of international law where certain standards have been nearly universally accepted, such as laws against piracy or slavery.
Nature, definition and sources
A central challenge in recognizing customary law is determining the appropriate methodology to identify which practices and norms actually constitute it. Some scholars argue that classic Western theories of jurisprudence cannot be easily reconciled with conceptual analyses of customary law, and thus have characterized customary law norms in their own terms. There remains disagreement on this point, with some preferring the contributions of H. L. A. Hart, who argued that his concept of law solves the conceptual problem of how customary law principles may be identified, defined, and how they operate in regulating social behavior and resolving disputes.
As an indefinite repertoire of norms
Customary law can be understood as an indefinite repertoire of norms. In some societies, such as the Tswana, the vast array of existing norms is seldom classified into categories, leading to what scholars term an undifferentiated normative repertoire. This lack of classification, along with the co-existence of overtly incompatible norms, allows for flexibility in dispute settlement and serves as a strategic resource for disputants. Inconsistencies between norms are typically resolved by elevating one norm from the literal to the symbolic, accommodating both in different realms of reality.
This process is highly contextual, meaning norms cannot be viewed in isolation and are open to negotiation. While a small number of norms are considered non-negotiable, the vast majority are given substance contextually. Outcomes of specific cases can change the normative repertoire, as it is seen to be in a constant state of formation and transformation, with changes justified as recognition of de facto observations of transformation.

Lore & Background
Customary law is defined as the set of customs, practices, and beliefs that a community accepts as binding rules of conduct. A central issue is determining the appropriate methodology to identify what practices constitute customary law. Some scholars, like John Comaroff and Simon Roberts, have characterized customary law norms in their own terms, while John Hund critiques their approach and prefers the contributions of H. L. A. Hart, arguing that Hart's The Concept of Law solves the conceptual problem of identifying and defining customary law principles.
Comaroff and Roberts' work 'Rules and Processes' details the body of norms constituting Tswana law, distinguishing melao (rules pronounced by a chief) from mekgwa (norms becoming customary law through traditional usage). They note the 'undifferentiated nature of the normative repertoire' and the coexistence of incompatible norms, allowing flexibility in dispute settlement. Outcomes of specific cases can change the normative repertoire, and a chief's legitimacy directly determines the legitimacy of his decisions.
Hund challenges Comaroff and Roberts' flexibility thesis, drawing from Hart's analysis to distinguish social rules (with internal and external aspects) from habits (external only). He identifies two forms of rule skepticism: first, that customary law content derives from practice so no objective rules exist; second, that rules are not arrived at deductively but are driven by personal or political motives. Hund argues these are misconceptions based on failure to acknowledge the internal element of social rules.
Reader's Guide
Customary law's significance lies in its role as a foundational source of legal norms in both local communities and international law. The debate between scholars like Comaroff and Roberts versus Hund highlights fundamental tensions in legal theory: whether customary law is a flexible repertoire of negotiable norms or a system of binding social rules identifiable through internal attitudes. Comaroff and Roberts emphasize the contextual, strategic use of norms in Tswana dispute resolution, where outcomes can transform the normative repertoire.
Hund, following Hart, insists on the importance of distinguishing social rules from mere habits through criteria such as societal criticism of deviation and the perception of a common standard. This unresolved dispute shapes how customary law is understood and applied, particularly in postcolonial legal systems and international law contexts like prohibitions on piracy and slavery. The legacy of customary law includes its ongoing influence in legal pluralism and the recognition that law can emerge from social practice rather than solely from state legislation.
Frequently Asked Questions
What is Customary law?
Customary law refers to long-standing patterns of behavior within a community that are treated as legally binding, even though no legislature ever formally enacted them. Also called consuetudinary or unofficial law, it sits squarely within the field of legal theory and jurisprudence.
How does a practice become legally binding as Customary law?
A practice gains legal force when it is consistently observed and the relevant actors treat it as a matter of legal obligation or necessity, a concept known as opinio juris. Without that shared sense of duty, the behavior remains mere habit rather than enforceable law.
What kinds of rules fall under Customary law?
Most customary laws address long-established community standards and local practices. The term also extends to international law, where near-universal acceptance of certain norms—such as prohibitions on piracy or slavery—elevates them to the status of customary legal rules.
