Archaic term for a formal written legal document such as a bond, deed, or contract. Not used in modern Japanese; encountered only in historical contexts.
古文書には、土地の売買に関する券文が残っている。
In old documents, deeds concerning land transactions remain.
The historical derivation is uncertain; the spelling 券文 combines 券 (certificate, ticket) and 文 (writing, document), suggesting a written certificate or deed.
