PIP tribunal

Hi deecom,
I have helped many people at tribunal and never had the tribunal ask any personal questions about PIP or disabilities of the supporting relative.
I am sure that your support will really help your sister. I can see no reason why your support will jeopardise your own PIP claim.
You are perfectly able to attend your sister's tribunal hearing. If you wish, you can give evidence and tell the tribunal what difficulties has and/or help she needs. Or alternatively you can just be present for moral support.
The tribunal will ask who you are, and maybe your address but there shouldn't be any other questions about yourself - the tribunal is to resolve whether your sister meets the requirements for PIP.
Your own personal circumstances are not relevant.

I hope this helps.
