He was born into the Buzád branch of the gens (clan) Hahót as the son of voivode Csák I.
[2] From 1256 to 1257, he functioned as bearer of the sword, which was a minor office in the royal court of Béla IV of Hungary (meanwhile his father was the master of the treasury).
However Ottokar II of Bohemia then the increasing powerful Kőszegi family captured the clan's all castles in the following years,[5] causing the Buzád branch's move into Center Zala.
Csák II settled down in Csány (today Zalacsány) after Ottokar's invasion, possibly he was that family member who built the local Zsidóvár ("Zsidó Castle").
Csák II functioned as master of the treasury for Elizabeth the Cuman, the widow of Stephen V of Hungary in 1286.
