A daughter of the Wall Street tycoon Zalman Bernstein is filing an injunction against the board of directors of a cooperative apartment building at 150 Central Park South to prevent it from forcing the sale of an apartment worth millions of dollars that she inherited from her father.

When the Sanford C. Bernstein & Co. founder died in 1999, he left his shares and proprietary lease to his Hampshire House apartment to his daughter, Rochel Leah Bernstein, 23, effective July 1, 2006, but the building’s board of directors rejected her application to transfer the stock and lease to her name, according to a suit filed yesterday in state Supreme Court in Manhattan. After failing to come to terms with the board, in May Ms. Bernstein listed the apartment for sale with the New York real estate firm Prudential Douglas Elliman for $17.5 million.

On July 30, a lawyer for 150 Central Park South Inc., David Fingerhut, sent Ms. Bernstein a letter through the attorney for her father’s estate in which he asserted that the asking price for the apartment was “unrealistically high” and “not a good faith attempt to sell,” and he threatened that the board would vote to terminate the proprietary lease if the apartment was not otherwise sold “expeditiously,” according to the complaint. The rules of the co-op do not allow buyers to finance any portion of their purchase.

The Bernstein’s “unique” seven-room, five-bath residence was created from two apartments on the 25th floor of the Hampshire House and is the “only apartment available for purchase on Central Park South on a high floor with two terraces and a magnificent view of Central Park,” according to the complaint. It features prewar details and three walls of sweeping, unobstructed views facing north, east, and south, according to its listing on the Elliman Web site.

Two other apartments in the building are listed by Elliman, a two-bedroom, two-bath unit at $3.2 million, and a one-bedroom, one-bath apartment at $1.7 million.

A broker involved in the sale said it is not unusual for an apartment in an all-cash building at this price level to remain on the market for six to 12 months, according to the suit.

Mr. Fingerhut did not return repeated calls for comment yesterday evening.

Ms. Bernstein’s mother, Elaine “Mem” Bernstein, her father’s widow, currently lives in the apartment, which Ms. Bernstein, who has a home outside the city, uses when she visits New York, according to the complaint.

Bernstein founded his securities firm in 1967 and it grew to manage more than $80 billion in assets, according to his obituary in the New York Times. Later in life, he converted to Orthodox Judaism, changed his name to its approximate Hebrew equivalent, Zalman, moved to Jerusalem, and gave hundreds of millions of dollars to Israeli causes and charities, according to the obituary.
