Crypto & Virtual Assets Expert Witness

What Is An Expert Witness?

An Expert Witness is an individual with expert knowledge within a certain field or discipline. We allocate the most suitable representative for your case to ensure that we are able to provide independent expert reports for your case. Our Expert Witnesses will provide impartial, truthful and independent opinions, even if they do not help your case. They are there to provide an expert opinion to the court and will always adhere to the Criminal Procedure Rules.

What Is An Expert Witness Report?

The purpose of an Expert Witness Report is to provide the court with an expert opinion on the case to allow a decision to be made. Within this report, the facts and the expert opinion will be clearly separated.
