LOS ANGELES — Ervin Cohen & Jessup, a business firm in Beverly Hills, Calif., has acquired 13 lawyers from Moldo Davidson Fraioli Seror & Sestanovich, including its name partners, in part to build its insolvency practice amid the current recession.

The combination, which becomes effective on Feb. 1, brings the total number of lawyers at Erwin Cohen & Jessup to more than 50.

“We want to boost our insolvency practice, and they wanted to boost their litigation practice and real estate practice,” said Randall S. Leff, a partner and member of the executive committee at Ervin Cohen & Jessup. “The economy created this opportunity for us to acquire these lawyers.”

Before the deal, Ervin Cohen & Jessup had one partner and one associate focused on bankruptcy work, he said.

The new lawyers include name partners Byron Moldo, Peter Davidson, Patrick Fraioli, David Seror and Tom Sestanovich. They also include partners Jeffrey Glassman, Ken Miller and Howard Camhi; one senior counsel, Alan M. Bergman; three lawyers of counsel, David Bricker, James A. Kohn and Bernard B. Nebenzahl; and one associate, Kimberly D. Lewis.

The move leaves eight lawyers at Moldo Davidson, which effectively dissolves with the deal, Leff said. While three secretaries also are joining, the deal does not involve administrative staff, he said. The group will move to Beverly Hills from Century City, Calif., where Moldo Davidson was located.
