Supporting Evidence

Hello

I am getting my dad and mum to UK on a standard visitor visa, I was just filling the applications, just got a doubt.

My mum doesn't have any bank account and my dad is supporting/sponsoring her.

They are applying at same time but because they apply on different applications, does the evidence like bank statements etc needs to provided twice?

mind you myself and my dad will be sponsoring my mum and we have the documents already in our dads application

please let me know.

No just provide it once

which says

if you are applying as a family/group you do not need to provide multiple copies
of the same documents

under Section4
