A legal malpractice case filed by a lawyer against Greenberg Traurig and former Greenberg shareholder Leslie Corwin has been settled.

The settlement came about six weeks after a state appeals panel sustained the case against the firm and Corwin, an expert on partnership law who is now a partner at Blank Rome. A trial was scheduled for October.

The parties had settled by Friday, according to court records. Terms were not made public.

“Although we continue to believe the case lacked merit, we are pleased to have closure on this matter,” a Greenberg spokeswoman said Monday.

The malpractice suit was brought in 2009 by Allen Roberts, now an Epstein Becker & Green member, against Greenberg and Corwin, who had represented Roberts in an arbitration against a firm he founded, Roberts & Finger, to recover his share of partnership interest.

In Roberts v. Corwin, 115370/2009, Roberts claimed Greenberg was negligent in failing to prove liability against his former partners and failing to designate an expert witness. Roberts claimed he “went from being in the position of recovering more than $5.2 million,” plus fees and costs, “to paying approximately $1 million.”

In 2013, Supreme Court Justice Marcy Friedman denied defendants’ motion to dismiss or to disqualify Epstein Becker. In a separate ruling, the court also denied Greenberg and Corwin’s summary judgment motion.

An Appellate Division, First Department, panel affirmed on both decisions (NYLJ, June 20).

Roberts was represented by John Houston Pope, a member at Epstein Becker. James Flynn, the firm’s general counsel, declined to comment. Roy Reardon, a Simpson Thacher & Bartlett partner, represented Greenberg and Corwin.
