Brian Kabateck first met Vartkes Yeghiayan when he asked him to assist in a class action Yeghiayan had filed against New York Life Insurance Co.

The suit asserted a novel theory: Des­cendants of the 1.5 million Armenians who were killed between 1915 and 1923 in what is now Turkey were owed payments on life insurance policies held by the victims. Kabateck took the case and brought in high-profile lawyer Mark Geragos, who had known Yeghiayan for decades and was a family friend of the lead plaintiff.
