Expert witness

If you are the plaintiff or defendant in a court case, you can ask an expert witness to support your claims.

Role of the expert witness

The role of the expert witness is to help the court gain a better understanding of the facts by providing expert knowledge about certain elements, for example by:

• estimating the value of a piece of jewellery, work or art or comic book;
• explaining the physical or mental state of the accused;
• examining the contents of a document.

For this purpose, the expert witness must answer the questions posed by the lawyers for the prosecution and defence.
