Firm Overview

Located in downtown Orlando, we represent plaintiffs and defendants in both state and federal court in complex business and commercial litigation, arbitrations, appeals, and significant personal injury and wrongful death matters. The firm has a wide range of clients, from local individuals, families and small businesses, to large publicly traded companies. We are also often retained by lawyers and law firms to represent them and are proud of our reputation as a lawyer’s law firm.

Our attorneys are actively involved, not only in their local bar, but statewide as well, with past presidents of the Orange County Bar Association, past presidents of the Orlando Chapter of the Federal Bar Association, and past members of The Florida Bar Board of Governors.  The firm’s attorneys have also held leadership roles in The Florida Bar Foundation and The Legal Aid Society of the Orange County Bar Association. We are grateful for our success and believe in giving back.


We have received local and statewide recognition for our pro bono service, and we continue to devote significant time and resources to providing pro bono legal services to those most in need through the OCBA’s Legal Aid Society.

Areas of Practice

For over forty years, our clients have turned to us to resolve their most trying problems and meet their most significant litigation needs. At King, Blackwell, Zehnder & Wermuth, P.A., we handle a variety of complex and complicated civil matters in state and federal court, both at the trial court level and on appeal.

  • Complex Business and Commercial Litigation

    We represent plaintiffs and defendants in complex business disputes and bet-the-company litigation

    Our clients include local individuals and businesses, many high-profile local and national lawyers and law firms, international defense contractors, major financial services companies and banking institutions, and Fortune 500 corporations.  We have enjoyed great success obtaining large verdicts and substantial settlements on behalf of our clients. We provide the highest quality legal representation and have a strong reputation for handling the most difficult and complex matters.

  • Appeals

    We are often retained to handle high-stakes, complicated appeals in both state and federal court

    Unlike most law firms, we also typically handle any appeals arising from the cases in which we served as trial counsel.  This efficiency is passed on to our client, who benefits from our historical knowledge of the cases and avoids the unnecessary expense of bringing appellate counsel up to speed.  We are also often retained to handle appeals of matters litigated by predecessor counsel, typically receiving those referrals from other attorneys and law firms.

  • Legal Malpractice Defense

    We represent lawyers and law firms when they require legal services

    Our firm has a long history of being retained by other lawyers and law firms, enhancing our reputation as a lawyer’s law firm. Over the years, we have represented law firm clients ranging from multi-national firms to solo practitioners, and in a variety of practice areas, from estate planning to family law to complex commercial litigation.  We are proud to assist our colleagues whenever the need arises.

  • Significant Personal Injury and Wrongful Death

    We have recovered large, including multi-million dollar, verdicts and settlements for our clients

    We represent the victims of significant personal injuries, as well as the family members of those who have lost their lives due to the fault of others.  We have been in the practice of personal injury law in Florida for over 40 years.
