Just to agree that it was a very straightforward procedure. The lady who came did not ask my mum to do anything, I believe that she could "Just tell", she was sympathetic, and it was all done and dusted quickly. My only issue was that, in spite of all the paperwork being done, when I telephoned the DWP on the first few occasions, I was not on the system, and it took a few months of them doing some administrative juggling to locate the forms which had been completed by our visitor, all a bit unnecessary.
