The German Federal Lawyers’ Act (BRAO) stipulates that practising lawyers shall purchase and maintain professional liability insurance to provide cover of at least 250,000 euros. Details are set forth in section 51 BRAO.

Dr. Thomas Foerster, Dagmar Foerster, Wilko Wiesner, Sabine Kötter, Stefan Knöllner, Merle König and Arkadi Arbetmann have purchased professional liability insurance for their work as lawyers from the Westfälische Provinzial Versicherung AG, Provinzial-Allee 1, 48159 Münster. This insurance does not cover indemnity claims from activities
  • via law practices or offices set up or maintained in other countries;
  • in connection with counselling on and dealing with non-European law;
  • performed by the lawyer before non-European courts.

The Federal Notaries’ Code (BNotO) enjoins notaries to take additional professional liability insurance providing cover of at least 500,000 euros. The details are set forth in section 19a BNotO.

Dr. Thomas Foerster, Wilko Wiesner and Sabine Kötter purchased professional liability insurance for their work as notaries from the Westfälische Provinzial Versicherung AG, Provinzial-Allee 1, 48159 Münster. The insurance cover does not include indemnity claims arising from activities in connection with offering advice on the laws of the United States of America (including the laws obtaining in individual states thereof) or Canada, unless the breach of official duty should lie in a failure to recognize the possibility that such could be governing law.

Professional rules of conduct (section 43a, par. 4 BRAO) forbid lawyers to represent opposing interests. Before agreeing to act for a client therefore, a case will be examined for conflicts of interest.
