The Law Code of Simeon of Rev-Ardashir, originally written in Persian, was translated into Syriac by a monk of Bēṭ-Qatrāyē. The Code's author, possibly to be identified with a rebellious metropolitan mentioned in the letters of Patriarch Īšoʿ-yahb III, aims to clarify theoretical scriptural law, and to address specific cases of inheritance law.

During the 6th century AD, Īshōʿyahb I, Patriarch of the Church of the East, produced a code of law dealing with questions raised by Bishop Jacob of Darai in the Gulf. Perennial Church issues include priestly conducts, ecclesiastical rankings, and ordinations. Legal matters for the faithful concern wills, marriages, vows, lending at interest, and swearing. Most interesting are names of church architecture that the Code gives, including bema, diaconicon, and qestroma, terms that are still used today.
