Matthias Kleinsasser is a seasoned litigator with experience in federal district court, bankruptcy court, and Texas state court. He is first and foremost a problem solver who takes a holistic approach to each matter, considering the client’s individual goals and concerns. He is equally comfortable negotiating a resolution to a dispute out of court or litigating a high stakes lawsuit.

Matthias is a member of our Investment Management & Private Funds Industry Group, as well as our Business Litigation, White-Collar Defense, and Restructuring & Insolvency Practice Groups. His experience in the fields of bankruptcy and creditors’ rights allows him to advise clients with respect to post-judgment remedies and debt restructuring options, enabling him to take a representation from the pre-suit stage to post-judgment proceedings with ease.

He regularly represents officers, directors, and other clients involved in investigations brought by regulatory agencies such as the Securities and Exchange Commission and the FDIC, as well as in private securities litigation. In contrast to many attorneys who seek to be highly specialized, Matthias prides himself on his ability to diligently represent clients in almost any kind of contested matter, be it a receivership, class action, arbitration, state court trial, or other dispute. He also frequently advises firm transactional clients with respect to contract negotiations and business disputes, particularly in the technology and healthcare fields.

Matthias has significant fraudulent transfer litigation experience. He has advised foreign clients on asset recovery procedures under United States law and is a Contributor to the CDR Essential Intelligence publication on “Fraud, Asset Tracing & Recovery.” He has also represented debtors, creditors, and trustees in virtually all aspects of business bankruptcy proceedings, including contested asset sales and debtor-in-possession financing.

Matthias began his legal career with a view from the other side of the bench when he served as law clerk to the Honorable D. Michael Lynn, U.S. Bankruptcy Judge for the Northern District of Texas. Prior to joining Winstead, he practiced with large law firms in Dallas and Fort Worth and with a respected business bankruptcy boutique.

Matthias is a co-author for Winstead’s Securities Litigation and Regulatory Enforcement blog.

Search Tips:

You may use the wildcard symbol (*) as a root expander.  A search for "anti*" will find not only "anti", but also "anti-trust", "antique", etc.

Entering two terms together in a search field will behave as though an "OR" is being used.  For example, entering "Antique Motorcars" as a Client Name search will find results with either word in the Client Name.


AND and OR may be used in a search.  Note: they must be capitalized, e.g., "Project AND Finance." 

The + and - sign operators may be used.  The + sign indicates that the term immediately following is required, while the - sign indicates to omit results that contain that term. E.g., "+real -estate" says results must have "real" but not "estate".

To perform an exact phrase search, surround your search phrase with quotation marks.  For example, "Project Finance".

Searches are not case sensitive.
