When you access this area you will be presented with a screen showing a list of documents that require checking. These are documents that the claimant has uploaded themselves and so need to be checked and approved.
Under the Documents ready for checking section click on the document you want to check.
The document check screen will open giving details and an attachment of a copy of the document (if required).
Once you have checked the document you can click on Checked at the top right if you are happy the details are correct.
