Famed litigator David Boies has sold his Manhattan residence at the Sherry-Netherland, an upscale hotel and co-op apartment building near the southeast corner of Central Park, with the property reportedly fetching nearly $6 million more than he paid for it about a decade ago.

Not so for Boies' Sherry-Netherland neighbor, exiled Chinese billionaire Guo Wengui.

Guo—a onetime client of Boies Schiller Flexner embroiled in multimillion-dollar malpractice and fee litigation with the firm—has been trying, off and on, to sell his penthouse unit in the 38-floor building since 2015, asking as much as $86 million at one point.
