Early Gaelic law tracts, first written down in the ninth century, reveal a society highly concerned with kinship, status, honour and the regulation of blood feuds. Scottish common law began to take shape at the end of the period, assimilating Gaelic and Celtic law with practices from Anglo-Norman England and the Continent. In the twelfth century, and certainly in the thirteenth, strong continental legal influences began to have more effect, such as Canon law and various Anglo-Norman practices. Pre-fourteenth century law among the native Scots is not always well attested, but extensive knowledge of early Gaelic Law gives some basis for its reconstruction. In the earliest extant Scottish legal manuscript, there is a document called "Leges inter Brettos et Scottos". The document survives in Old French, and is almost certainly a French translation of an earlier Gaelic document. It retained a vast number of untranslated Gaelic legal terms. Later medieval legal documents, written both in Latin and Middle English, contain more Gaelic legal terms, examples including "slains" (Old Irish "slán" or "sláinte"; exemption) and "cumherba" (Old Irish "comarba"; ecclesiastic heir).
