Proof of fund - joint account

Proof of fund. My wife and I have joint accounts in Bank of america. We got reference letter for BoA too. I am planning to attach 6 month statements along with that. Do I need to specifically need any thing else to prove my wife has access to the accounts (which is shown in reference letter addressed to her)? She is the primary.
