Abstract
Dealing with a medical expert assessment requires experience and perseverance of the lawyer. Exact knowledge about the expert opinion itself and the procedural options is of greatest importance due to the decisive impact of the medical expert assessment on the outcome of the lawsuit. The lawyer has to consider at any time of the process whether he can initiate an expert assessment, whether he has to evaluate, criticize or question obtained expert assessments, whether he has to challenge the expert or possibly has to introduce another expert into the lawsuit. The expert witness has to have professional knowledge and the lawyer as well as the court have to absorb this knowledge and use it accordingly.
