Hi Des
Although your daughter can speak on your behalf, there are three occasions when the DWP call handler will insist on speaking to you. This is just to confirm you understand various things and that you give permission for your daughter to speak on your behalf.
The information they will ask for can all be found on page 13 of the PIP guide. It just includes things like your DOB and your NI number and what medical conditions you have.
