If you think that you may be a vulnerable witness, you should discuss this with the person citing you
They will discuss your circumstances with you and whether it is appropriate to make an application to the court for you to use special measures to help you give your evidence.
They will tell you more about what the court needs to consider and may give you a second booklet for particularly vulnerable witnesses called Being a Witness – The Use of Special Measures. Download this booklet on the Useful Booklets page.
