The long-anticipated sale of the New York County Lawyers Association’s headquarters in Manhattan has failed to close after the prospective buyer defaulted and didn’t appear at the real estate closing, according to the bar group’s leader. Now, NYCLA’s plans to move to new offices are on hold.

Stephen Lessard, the group’s president, told the bar’s members on Tuesday that NYCLA’s board of directors terminated the sale agreement “due to a default by the prospective purchaser.”
