pip appeal for disabled uni student

gitaparmar,
In my experience of similar cases, I agree with everything Mike has said. You do act in place of the claimant so legally there is no need for your daughter to go, but I think she will have much more chance of success if she attends.

If she is there, that will enable the tribunal to gain more understanding of her condition, exactly what she can and cannot do and what you do for her. 

I completely understand your explanation of how she's able to be at university but needs an appointee. However, the tribunal will be far more likely to understand this, & not see it as inconsistent or contradicting the PIP descriptors if you both attend. Be prepared for the tribunal members to want to ask her questions rather than having you speak for her throughout - you will get a chance to add anything at the end.

I've helped other families in not dissimilar situations and whilst you can't predict questions you might get asked about whether your daughter understands how much money she has, whether she controls her bank account, whether she can take money out & spend it etc.

You may have done this already, but I'd recommend that you look through the PIP descriptors to understand which you think she should have been awarded. You might want to summarise the descriptors you think apply, and explain why, in a written submission to the tribunal - but you don't have to do this, it's not essential and lots of people win without sending in a submission. It's arguably a lot more important that you both attend.
