I have my DLA to PIP assessment at home on Wednesday but unfortunately my wife is in hospital, My daughter is travelling up to visit her mum so is going to be with me at assessment.in the morning...will she need ID for it? she is my step daughter of 30 years so knows me well as I helped to bring her up, but I wasnt sure of the requirements for relatives other than spouses. If she does would she need proof of family connection eg marriage certificate ? Thankyou.
