Church Statute of Prince Yaroslav is a source of church law in Old Rus', defined legal authority of church by the prince, his administration and churchmen. Yaroslav's Statute was a short legal code, regulated relationship between the church and the state, including demarcation of jurisdiction between church and princely courts, index of persons within the church jurisdiction, rules of family law and sanctions against moral violation. The statute was written at the 11th–12th century and remade during 13th–16th centuries, in Old Church Slavonic and Old Russian. It was one of the first church sources of Old Russian Law. Church Statute of Prince Vladimir and other Old Russian princely statutes served to closely purposes. But church jurisdiction was expanded in comparison with Vladimir's Statute. A part of the lawsuits in the Yaroslav's Statute was referred to the church jurisdiction, and a part - to joint jurisdiction of the church and the prince. One of the sources of the statute was Byzantine law, including Nomocanon. The statute was written on behalf of Kievan prince "Yaroslav, son of Volodimir, following my father's gift, have consulted with Ilarion, Metropolitan of Kiev and All Rus'".
The statute particularly concerns rules of family law: adultery, illegal marriage, divorce and others, and also sanctions against moral violation. Some offences, suppressed in Byzantium by ecclesiastical sanctions, were suppressed by secular criminal punishment in the Old Russian state. The statute also reflected medieval right-privilege: punishment was differentiated by estate of victim. According to Vasily Klyuchevsky the church court, described in the statute, deepened the concept of crime, expanded the concept of sanity and established sanction for prevention of violation.
