Houston lawyer Todd Zucker has sued his longtime partner, E. Michelle Bohreer, alleging she defrauded him by using more than $650,000 of their firm’s money for “extravagant personal expenses.”

In a dispute that presumably signals an end to the 13-year-partnership at Bohreer & Zucker, Zucker alleged in a petition filed in Harris County state district court on Tuesday, that Bohreer treated the firm’s operating account as her “personal piggy bank.”
