A: I'm uncertain, but this leads me to the impression the money is first landing in his account and then being transferred over to yours for payment of the bills.
If the money was being directly deposited into your account, I would tend to agree with attorney Bunce, nevertheless, I might just stick my heels in and provide the bank statements, (account numbers redacted), if trustee presses on the issue.
Since you are not married, and have no income, I think the attorney is simply trying to blunt any possible claim by the trustee that you are contributing to the "family" income in some way. I would ask the attorney specifically why he wants to see your bank records. If you don't get a clear answer, get a different BK atty.
