Faced with an expiring lease, lawyers from a prominent matrimonial boutique are combining with a growing real estate-focused New York firm.

Partners from Mayerson Abramowitz & Kahn, which has handled celebrity and high-profile divorces for decades, are joining Schwartz Sladkus Reich Greenberg Atlas, the firm announced Thursday. After the six matrimonial lawyers join on Jan. 1, 2019, the combined firm will have about 50 lawyers. Schwartz Sladkus will continue to keep the same name after the additions.
