Лозаннский мирный договор
In Western Thrace, under the terms of the 1920 Treaty of Sevres and 1923 Treaty of Lausanne, sharia courts historically had exclusive jurisdiction over the Muslim population in issues related to family law. Since 2018, Muslims in the region have been given the choice of registering a civil marriage and pursuing civil cases in the national court system. The Treaty of Lausanne also allows for the establishment of waqfs.
