A legal tradition or legal family is a grouping of laws or legal systems based on shared features or historical relationships.[1] Common examples include the common law tradition and civil law tradition. Many other legal traditions have also been recognized. The concepts of legal system, legal tradition, and legal culture are closely related.
The understanding of legal families and traditions has shifted over time. Early and mid-20th-century efforts at classifying legal systems commonly employed a taxonomic metaphor, and assumed that the affiliation of a legal system with a legal family was static and that mixed legal systems were an exceptional case. Under more recent understandings, legal systems are understood to partake of multiple legal traditions.
