The current SET(M) form says:
Evidence of your finances. Bank statements, building society savings book(s), pay slips or other formal documents as evidence of your and your partner’s ability to maintain and accommodate yourself and any dependants without recourse to public funds (see Note 7).Note 7 says:
We do not accept internet or cashpoint statements as evidence of finances. If you claim that a relative or friend is providing you with financial support (see question 7.5), in addition to evidence of your own finances, you must provide bank statements or other documents of the kind described above as evidence of their financial resources. The documents showing the finances available to you and to any person supporting you should cover at least the last 3 months. (emphasis added by me)
When I did my app in person earlier this month, I had three months' worth of bank statements for each of us (we don't have a joint account) - my checking, his checking, my savings, and my checking account back in the states. For the last one, I included a cover sheet noting how much the money was actually worth on the statement dates (using rates from
www.oanda.com), but this may have been me overthinking it.
I also had payslips for both of us - my partner's covered three months, though mine only covered two as I hadn't earned money in one of the previous three months. They didn't ask any questions about my earnings, though.
Given the importance of proving that you will not be a drain on public funds, I would suggest sending statements for both of you, including any savings accounts.
