Gersten Savage, once a 20-attorney litigation and transactional firm, presented an "aura of success" with its display of contemporary art adorning the walls of its Midtown offices; pricey Knoll and Bertoia chairs and personalized Gersten Savage cups and napkins; and its hiring of office managers and on-site IT staff, said lawyers who sublet space from the firm.

But only four months after settling in at 600 Lexington Ave., sublessee Grant + Appelbaum, a four-attorney matrimonial firm, was told by 35-year-old Gersten Savage that it was defaulting on its lease, its partners were departing and the subtenants would have to leave or be evicted, according to a lawsuit against Gersten Savage.
