I am renewing mum's Blue Badge. I have to provide a "proof of identity" - this is very difficult as marriage/divorce/birth certificates are long gone - thrown out along the way. Mum never had a Bus Pass and now has no Valid Driving Licence. However we do have an expired passport (with me for safe keeping years ago). The lovely lady who I spoke to at our local council was more than happy to accept a copy of the expired passport as proof. Thank heaven for a sensible approach! As many of you will know, as this wretched disease progresses too much of the Original person with dementia can disappear and so does the documentation to identify them. That expired passport is proving useful!
