thanks for your help- to save confusion she is NOT and never has been on ESA she is on DLA (the government are changing everyone over to PIP) please continue with any advice thank you

Hello, I’m trying to get an answer regarding the changeover from dla to ESA/pip. My friend’s mother suffers from severe borderline personality disorder; she has been on dla for over twenty years! and did have until recently home-help (Although I believe this is no longer the case) her daughter recently took her to a atos/maximus assessment from which I understand it was specifically because Dla is changing to pip and they are medically ‘re-assessing.’ People that are changing over? 1 is this correct? 2 I assume if this is correct will she afterwards be on esa + PIP, as other claimants are? Or just PIP. 3 she recently (because of this changeover) was asked to attend a medical assessment for PIP. From what I gather the PIP assessment is different/ more difficult than the esa assessment? Is this correct? 4 I believe that her daughter does not know how the assessment really works? The main question is if she fails (as we have been told many people do, first time around), are the procedures for preparing for the tribunal and/ or mandatory reconsideration the same as ESA? 5 In case of FAILURE, are the papers you request i.e. details of assessment, assessors etc and papers and forms and the names, codes of the paperwork, assessors etc exactly the same protocol as if you were requesting documents if you failed an ESA assessment? I.E if she fails could she be on no money until her tribunal appeal? thanks 6 I have also been told that the onus of providing the paperwork, evidence of the claimant’s illnesses is the responsibility of atos/maximus/ capita / etc rather than the claimant? Is this correct? 7 I also believe my friend was not armed with the correct information regarding assessments to benefit her mother as well as required- can anyone suggest anything? Thank you very much
