What documents are required when extending Dependant's visa?

[June28]

Hi All,


I have been in the UK now for 2 months. I still have not opened a bank account since we cannot prove my address in the u.k. I was wondering if we have to prove that my partner and I we're living at the same address through having the same correspondence.

Will other letters such as doctor's letter etc. be enough?

Also, what are the documents we have to submit when we apply for the visa extension?

Thank you
