Fort Lauderdale law firm Conrad & Scherer said it is joining forces with Miami law firm Kozyak Tropin & Throckmorton to recover millions of dollars lost to Scott Rothstein’s Ponzi scheme.

William Scherer filed suit last year against Rothstein’s now-defunct firm, Rothstein Rosenfeldt Adler, on behalf of several defrauded investors. The suit seeks to recover $160 million from Rothstein’s $1.2 billion scheme.

Kozyak Tropin & Throckmorton was brought in to “provide the additional expert attorneys and support staff we need to successfully pursue such a massive and complex court case,” Scherer said in a news release.

Kozyak Tropin & Throckmorton specializes in complex commercial litigation and bankruptcy matters.

Scherer’s lawsuit is believed to be the largest civil lawsuit in Broward County court history.
