Criminal Injuries Compensation Authority
The CICA has set up a major incident team to deal with applications from victims of the terrorist attack in London. This team will ensure there is a co-ordinated approach to the collection of evidence about the incident, and the consistent use of this evidence in our decision making process. Anyone who has been directly affected by this incident can find out about applying for compensation at www.gov.uk or call the CICA helpline on 0300 003 3601. Support in applying to the Scheme is available through the local Police and Crime Commissioner and local contact details can be found via the Victims Information Service (https://www.victimsinformationservice.org.uk/).
Legal aid for inquests is available to family members of the deceased. Legal Help (the advice and assistance level of legal aid) can cover all of the preparatory work associated with an inquest, for example to help families prepare written questions they would like the Coroner to ask. Additionally Legal aid for representation remains available through the Exceptional Case Funding Scheme (operated by the Legal Aid Agency (LAA)) and will continue to be provided where certain published criteria are met. Both Legal Help and exceptional funding for legal representation are subject to means testing, but the means test can be waived for both by the LAA where it is reasonable to do so.
