A year before her husband died, he wrote a will which specified that his brother, Thomas and Cecile would act as regents for Boniface, the heir to the County of Savoy. When Thomas died in 1259, Cecile continued as regent in Savoy. In this role, one of her first acts was to relieve St-Germain-sur-Séez from various taxes in exchange for their work to guide travelers through the pass of Petit-St-Bernard. As regent, she had her own seal for authorizing documents. Under her regency, Boniface's uncles, Peter II and Philip I continued their practice of acquiring territories and influence in surrounding regions in the name of the count.
