About the NRGD

In the Netherlands, the Experts in Criminal Cases Act demands high standards regarding the quality, reliability and competency of experts.


The above Act came into force on 1 January 2010 and resulted in the Netherlands Register of Court Experts (NRGD) being the first register of experts to have a statutory basis, an independent position and structural funding. The NRGD is managed by an independent Board of Court Experts. The Register of Experts in Criminal Cases Decree determines primarily how the NRGD is managed.

Alongside the Register, the Experts in Criminal Cases Act also strengthens the position of defence counsel. As such, the Act gives the accused the right to request an additional investigation or counter inquiry.

Optional Registration

Registration with the NGRD is not an essential requirement for acting as a forensic expert. However, being successfully assessed by an objective and competent committee, your specialist forensic expertise is legally acknowledged and accredited. Since the Register safeguards the quality of court experts, admittance of non- registered experts must be thoroughly motivated by the court in each specific criminal case. Whereas, on the basis of your name or field of expertise, you can be easily found in the Register by judges, public prosecutors, lawyers and other users.

Increasing number of field-specific standards

Although only well-defined expertise which contributes to gathering meaningful, objective and reliable information will be considered for admission in the Register, it might be possible that your field of expertise has not yet been added to the Register. NRGD will keep you updated about new standards and standardized fields through its website and via NRGD’s Newsletter. At this moment, only the Criminal Court is served by the Register, but expansion to both Civil and Administrative Courts is possible in the near future.
