This is the first comprehensive treatment in any language of the history of customary law in Hungary, from the thirteenth to the twentieth centuries. Hungary''s customary law was described by Stephen Werboczy in 1517 in the extensive law code known as the Tripartitum. As Werboczy explained, Hungarian law derived from the interplay of Romano-canonical law, statute, written instruments, and court judgments. It was also responsive, however, to popularconceptions of the law''s content and application, as communicated through the lay membership of the kingdom''s courts. Publication of the Tripartitum was intended to make the law more certain by fixing it in writing. Nevertheless, its text was customized by actual use, in the same way as the statute laws of the kingdomwere adjusted as a consequence of court practice and of errors in their transmission.The reputation attaching to the Tripartitum and Hungary''s insulation from the Roman Law Reception meant that the Tripartitum continued to retain authority until well into the nineteenth century. Attempts to replace it foundered and it was the principal text on which the courts and the schools relied, not only in Habsburg Hungary but also in Transylvania. Courts, nevertheless, continued to modify its provisions in the interests of rendering judgments that they deemed either tobe right or in conformity with developing practices. Even after the establishment of a parliamentary form of government in the nineteenth century, a strong customary element attached to Hungarian law, which was amplified by the association of customary law with national traditions. The consequence was that Hungarymaintained aspects of a customary law regime until the Communist period.
