Steven Leber filed a $4 million lawsuit against Paul J. Konigsberg and his accounting  firm, Konigsberg & Wolf charging Konigsberg with negligence and professional malpractice with respect to a Madoff account opened by Leber in 1998.   

The suit was initially filed in Palm Beach District Court in March 2009 and subsequently removed to the Southern District of Florida in April 2009.

The complaint can be read here. (The actual complaint begins on p. 13.)

Konigsberg's response to the complaint can be read here. While admitting he does have a fiduciary responsibility to Leber, he claims the suit is not valid for several reasons.  

Paul Konigsberg, of course, is the CPA who owned a small percentage of Madoff Securities International Limited in London. He also prepared the 990s for the Madoff Family Foundation.

Konigsberg and his wife accompanied the Madoffs on a 2004 ski trip to Switzerland.

Konigsberg's homes in Greenwich CT and Palm Beach Gardens FL are both held in the name of his wife, Judith, only.

Konigsberg had a number of Madoff accounts under his name including two in the name of the Westlake Foundation. Paul J. and Judith Konigsberg are officers and directors of the foundation.
