The Prefecture of the Papal Household is the office in charge of the Papal Household, a section of the Roman Curia that comprises the Papal Chapel (Cappella Pontificia) and the Papal Family (Familia Pontificia).
As the apostolic constitution Pastor Bonus states, "The Prefecture of the Papal Household looks after the internal organization of the papal household, and supervises everything concerning the conduct and service of all clerics and laypersons who make up the papal chapel and family. It is at the service of the Supreme Pontiff, both in the Apostolic Palace and when he travels in Rome or in Italy."
The Prefecture has competence for matters that once belonged to several offices, now suppressed: the Ceremonial Congregation, the offices of the Majordomo, the Master of the Chamber, and the Master of the Sacred Apostolic Palaces, and the Heraldic Commission for the Papal Court.
The Papal Family has lay members as well as clergy. Among the ecclesiastics who have membership are other high officials of the Roman Curia, but also all apostolic protonotaries, Honorary Prelates and Chaplains of His Holiness, while the lay members include all Gentlemen of His Holiness, the Commandant of the Papal Swiss Guard and the Counsellors of the State of Vatican City.
The Papal Family includes among its members the Theologian of the Pontifical Household, currently Father Wojciech Giertych, and the Preacher to the Papal Household, currently Father Raniero Cantalamessa. Father Giertych's predecessor was Georges Marie Martin Cottier, O.P.
