Richard Des Saulx, de Salicibus, is described in a list of 1403 as a priest of Rouen, master of arts and bachelor of law.

In 1414 he is described at Rouen as jurisperitus, advocatus curie officialis. In 1423 the canons sentenced him to do penance for a filthy word spoken while he was pleading against Canon Jean de La Porte.

We note that in 1435 he was dismissed by decision of the church court of Rouen from his pretensions to the benefice of Theuville aux Maillots, which Henry VI had given to Aubert Morel in 1419.
