Otto was the son of Hugh of Châlons and Adelaide, Countess Palatine of Burgundy.[2] Upon his father's death in 1266/7, he became Count of Châlons. In 1267, the pro-French Otto IV got in conflict with his half-uncle John I of Chalon-Arlay, who was supported by his vassals.[3] His mother, Adelaide, died on 8 March 1279, and Otto inherited her county. However, he was unable to secure real power in the county until 1295.[4] His elder daughter Joan II succeeded in the County of Burgundy, which was later given as dowry on her marriage to Philip.[5]
His wife Mahaut drew up a contract on 4 June 1312 with the famous tomb maker Jean Pepin de Huy to make a tomb.[6] The contract specifies a tomb made of stone and alabaster.[6] Otto was to be shown as an armed knight with a shield, sword and armor.[6] A lion was shown beneath his feet with two angels to support the pillow under his head.[6] The tomb no longer exists, but the designs have been preserved.
