A patroness of troubadours such as Giraud de Calanson and Peire Raymond, the queen became involved in a legal dispute with her husband concerning properties which formed part of her dower estates.
In 1177 she entered the county of Ribagorza and took forcible possession of various castles and fortresses which had belonged to the crown there.
After her husband died at Perpignan in 1196, Sancha was relegated to the background of political affairs by her son Peter II.
She retired from court, withdrawing to the Hospitaller convent for noble ladies, the Monastery of Santa María de Sigena, at Sigena, which she had founded.
There she assumed the cross of the Order of St John of Jerusalem which she wore until the end of her life.
The queen mother entertained her widowed daughter Constance at Sigena prior to her leaving Aragon to marry Emperor Frederick II in 1208.
