In 1217 and 1221 he also granted Bellevaux the right to the catch of the fisheries of La Roche and Ray on set dates of the year.

Othon ceases to be mentioned after 1225, when he is commonly held to have resigned the Duchy of Athens to his son Guy I and returned home to Burgundy with his wife, although this is unsubstantiated. He died sometime before 1234, since in that year his other son called himself "a son of the former lord Othon, duke of Athens" (filius quondam domini Ottonis, ducis Athenarum).

Family
Othon's wife name was Isabel (and its variant Elisabeth). She is generally described as the daughter and heiress of Guy, lord of Ray-sur-Saône in the Free County of Burgundy. According to Longnon however, she was the daughter of Clarembaud IV of Chappes, a lord from Champagne. She gave birth to two sons, Guy and Othon. Othon inherited the lordship of Ray. Guy is traditionally held to have inherited La Roche, while the duchy is said to have passed to a nephew of Othon's also named Guy. Longnon has challenged this view according to a chart in which Othon of Ray, son of Othon de la Roche, presents the duke Guy as his brother - meaning that Guy would be Othon's son and not his nephew. While most members of the La Roche family lived in the Free County of Burgundy, some of them settled in Athens. For instance, a great-grandson of his, Walter, was a member of the Chapter of the Parthenon in 1292.
