As a victim, you may be called upon to be a witness in court. All witnesses are sent a notice to attend court which is called a summons (in the Magistrates' Court) or a subpoena (in the County and Supreme Courts).
This notice tells you when and where the case is going to be held. If you receive a summons or subpoena, you must attend court.
If you do not receive a summons or subpoena, you don't have attend the court case. If you do decide to attend, you should let the police investigator know.
If you are going to court, make sure you have a copy of your police statement to take with you. If you don't have a copy, contact the police investigator to get one.
