Lauren M. Wacker

Ms. Wacker concentrates her practice on business, employment, real estate and tort litigation. Lauren has significant experience in all aspects of the litigation process, including pre-trial investigation, initial pleading and motion practice, discovery, trial and appeal. She has represented clients in both state and federal courts, including Missouri Courts of Appeals, the Supreme Court of Missouri and the Eighth Circuit Court of Appeals. 

Lauren represents a wide variety of clients, including real estate developers, lenders, loan servicers, large-scale lessors, small businesses, manufacturers, student loan guarantors and fiduciaries. She recently successfully defended a mortgage lender against a class action petition seeking to compel a change in Missouri law. The plaintiffs advocated that a mortgage lender should be liable for the unauthorized practice of law if it procured form legal documents from a third party without the assistance and review of a Missouri-licensed attorney. After obtaining summary judgment in the lender’s favor, Lauren drafted the winning respondent brief before the Supreme Court of Missouri, resulting in a published opinion (Binkley v. American Equity Mortgage, Inc., 447 S.W.3d 194 (Mo. 2014)). 

Lauren’s trial experience includes the defense of a real estate redeveloper in a two-week jury trial involving a complex redevelopment transaction, which resulted in a favorable defense verdict in excess of $8 million.  Lauren also helped obtain a $4.5 million verdict on behalf of a national transportation company in a three-day jury condemnation trial.
