Validity Finance, the litigation funding firm founded earlier this year by the former leader of IMF Bentham Ltd.’s U.S. operations, has added a series of bold-faced names in New York.

The company, which is backed with up to $250 million primarily from private equity firm TowerBrook Capital Partners, is bringing on former Cooper & Kirk litigation attorney William Marra, once a clerk to U.S. Supreme Court Justice Samuel Alito, as portfolio counsel, and adding Proskauer Rose former chairman Allen Fagin to its board. Former New York federal judge John Gleeson, now a partner at Debevoise & Plimpton, has been tapped as outside counsel to advise on investment opportunities.
