The Department only releases information to a third party in line with Data Protection Legislation.
In regard to War Disablement Pensions, disclosure to other Government Departments, local authorities and other public bodies can be made under Schedule 2, Paragraph 5 of the Data Protection Act 2018. As War Disablement Pensions can affect other Social Security Benefits, the legislation allowing the sharing of personal information for state benefit and war pension purposes is Section 3 of the Social Security Act 1998. This legislation can be found on the Gov.UK website at the following link - https://www.legislation.gov.uk/ukpga/1998/14
Additionally, information is shared with third parties at the request of the claimant themselves, either in the form of authority for representation, or written authority.
