The article deals with an extremely rare case of divorce in Carniola at the end of the 17th century. Ten years after the wedding of count Jurij Andrej Trilek to countess Suzana Felicita Gallenberg, the ecclesiastic court of the Ljubljana diocese pronounced the separation from bed and board and Jurij Andrej guilty. This was followed by a long-standing lawsuit in the secular court for the fortune demanded by the wife. The husband, however, rejected her demands maintaining that there was no legal basis for this since none of their mutual financial agreements had stipulated a divorce.
