For something like this I would recommend that co-op hire Adam Leitman Bailey of Adam Leitman Bailey, P.C..
He is the best in the business and has done a lot of work for my family over the years. Just have your friend tell him that I referred him. He is CC’d on this email.
Another friend of mine is looking for a landlord-tenant lawyer. Basically, he owns an apartment in a co-op in Manhattan. The co-op has a commercial tenant (a restaurant) that is suing the co-op. As such, the co-op is looking for a good landlord tenant lawyer to represent it as the landlord. Do you have any recommendations?
