The GDPR does not prevent an individual making a subject access request via a third party. Often, this will be a solicitor acting on behalf of a client, but it could simply be that an individual feels comfortable allowing someone else to act for them. In these cases, you need to be satisfied that the third party making the request is entitled to act on behalf of the individual, but it is the third party’s responsibility to provide evidence of this entitlement.
The Information Commissioner’s Office provides more detailed guidance on third party DSARs and on requests for information about children.
