In 2003, Pallonji gave up his Indian citizenship to become an Irish citizen "on the basis of his marriage to an Irish-born national", Pat "Patsy" Perin Dubash, who was born in September 1939 at Hatch Street Nursing House in Dublin. He remains in residence in Mumbai. The family's interest in Ireland is ascribed, in part, to their love of horses; Mistry owns a 200 acres (0.81 km) stud farm and a 10,000-square-foot (930 m) home in Pune, India.
