An exequatur (pronounced: /ˌeksəˈkwādər/) is a legal document issued by a sovereign authority allowing a right to be enforced in the authority's domain of competence. The word is a form of the Latin verb exequi, and means let it be executed in Latin.
With the Sisters of Perpetual Indulgence, the acceptance of a house's request for an exequatur is considered a milestone and is usually accompanied by great celebration. The Sisters from houses hundreds of miles away frequently make the trip to join the celebration.
