On 3 May 1386 Bernat participated publicly in a partimen (poetical debate) with Jacme Rovira before the judges Germà de Gontaut and Ramon Galbarra at the Consistori del Gay Saber in Toulouse.
Bernat produced only one surviving work, a combination of maldit and comiat that began Cercatz d'uymay, ja.n siatz belha y pros.
In the tradition of those genres, Bernat describes his lady as unjust and indiscrete and renounces her.
The terms he uses make it clear that he has not praised this woman in any previous poem.
This poem, despite its generic rhyme scheme and metre, was moderately popular: it was cited by Francesc Ferrer and Francesc de la Via in the next century and its melody was adopted for a certain song of the Misteri d'Elx.
