Succeeding the foreign cleric Bonaventura, Thomas functioned as provost of the collegiate chapter of Vasvár between 1272 and 1279.
[2] Despite the unanimous request of the cathedral chapter of Várad, papal legate Philip of Fermo refused to confirm Thomas' election.
Philip objected that Thomas was not ordained to the priesthood within one year of his election as provost, despite the decrees of the Second Council of Lyon.
Pope Martin IV accepted the argument and authorized the metropolitan John Hont-Pázmány, Archbishop of Kalocsa and his two suffragans – Pouka of Syrmia and Gregory of Csanád – on 18 June 1282 to confirm Thomas' election.
He left his family a considerable fortune at his death, who, however, soon began to litigate with each other for the estates and servants.
