Can a Subject Access Request be made by a third party?

The Information Commissioner offers the following advice.

“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. This might be a written authority to make the request or it might be a more general power of attorney.

If you think an individual may not understand what information would be disclosed to a third party who has made a subject access request on their behalf, you may send the response directly to the individual rather than to the third party. The individual may then choose to share the information with the third party after having had a chance to review it.

There are cases where an individual does not have the mental capacity to manage their own affairs. Although there are no specific provisions in the GDPR, the Mental Capacity Act 2005 or in the Adults with Incapacity (Scotland) Act 2000 enabling a third party to exercise subject access rights on behalf of such an individual, it is reasonable to assume that an attorney with authority to manage the property and affairs of an individual will have the appropriate authority. The same applies to a person appointed to make decisions about such matters – in England and Wales, by the Court of Protection.”
