In 1220 Guillaume II de Sabran, a nephew of William IV, who claimed Forcalquier and had been in revolt in the region of Sisteron, was neutralised in part through the mediation of the Archbishop of Aix, Bermond le Cornu.
By 1217 or 1220 Garsenda had finally ceded Forcalquier to her son and handed the reins of government over.

Garsenda retired to the monastery of La Celle around 1225.
In 1242, she went to visit her newly born great-granddaughter, Beatrice of England, and her parents in Bordeaux.
 As the father of infant Beatrice, Henry III of England, was engaged in a war in France at the time, she brought 60 knights to his service.
Garsend may have been alive as late as 1257, when a certain woman of that name made a donation to a church of St-Jean on the condition that three priests be kept to pray for her soul and that of her husband.
