Jewelry heiress Ilaria Bulgari sued her older sister Thursday in the Southern District of New York, alleging that Veronica Bulgari improperly withheld information about two trusts created by the women’s father.

David Boies of Boies Schiller Flexner and Peter Skinner of Morrison & Foerster represent Ilaria Bulgari, who claims she only learned she was a beneficiary of the trusts in February 2020, about 15 years after they were created in the course of their parents’ divorce.
