In over fifty years of legal practice, Morton H. Rosen has become known as a recognized authority in the field of cooperative and condominium law.

In the 1970s, when open commercial spaces in New York City were being illegally converted into residential space and rented to unsuspecting tenants, Mr. Rosen successfully represented and defended various tenant groups in litigation, while aiding them in organizing rent strikes against landlords who sought to profit from such illegal activity. From the 1970s into the 1980s, when many building owners in New York began converting their properties to cooperatives and condominiums, Mr. Rosen represented countless numbers of tenants and tenant groups who sought his counsel in the interpretation and negotiation of offering plan terms and purchase contracts. His work in both litigation and transactional work became well-known in New York’s real estate community.

After numerous apartment buildings were converted into common-interest communities, various Boards of Directors and Managers sought Mr. Rosen’s representation as general counsel to their respective buildings. Aside from day-to-day legal guidance provided by Mr. Rosen, he frequently litigated lawsuits on behalf of Boards and their buildings against Sponsors who engaged in misdealing. Mr. Rosen stood at the forefront of litigation that affected common-interest communities, and his record of involvement in landmark condo-coop cases speaks for itself.

In recent years, Mr. Rosen is still a counselor in real estate law, and he now focuses much of his practice on transactional matters. Moreover, Mr. Rosen counsels the younger practitioners of his firm to aid in their professional growth, encouraging them to be creative when seeking resolution in common-interest community disputes. Mr. Rosen firmly believes that, although litigation is sometimes necessary, amicable resolution in common-interest communities, through mediation or otherwise, is preferable to litigation. “Bad blood between residents in a community benefits no one,” says Mr. Rosen. “Lawsuits eventually end, and someone will be declared a winner, but the parties on both sides almost always must return to their communities and live with one another. We have a responsibility to ensure that our clients are aware that the effects of litigation go beyond the courthouse doors, and can have a long-lasting impact on their lives at home and within their respective communities.”
