When, in 1320, his lover, Raymonde Piquier, became pregnant, Bélibaste persuaded Pierre Maury to marry her. Then, a few days later, he dissolved the marriage and salvaged his own reputation by making it appear the child was Maury's. Eventually he was betrayed by the spy Arnaud Sicre in the service of the Inquisition. Bélibaste was taken to Villerouge Termenes, interrogated and burnt at the stake there.
