What’s evidence is required?

Hello.
So I’m re-applying for estrangement for my last year of university and I was just wondering what evidence I’ll need to show I don’t have contact with my parents? My student advisor said that student finance wont ask for another application form as they already have that, But I’m confused as to what else I would provide them?.
I’ve heard rumours that I’d need to show them bank statements but I’m not comfortable with showing anybody that, so what would be classed as “evidence”. ?

Hi there, has the team requested evidence from you to confirm your estranged? Thanks, Karen

well, when I was going through the process of re-applying , I saw a little blue box that came up saying “we may require more evidence from you” etc etc, I had to stop with the application process because there’s a few more things I need to sort out.

Do you know what evidence they’ll ask for?

Thank you.
