Must I reveal my personal information along with my mothers for banking?
We cannot give legal advice. The following is not a substitute for the advice of a local attorney. But we hope the information will be useful.
If you have a record of a past renewal where your information was blacked out, you could show this to them. They might be willing to let you do it again. They aren't invading your privacy - that would only happen if they got your information without your consent. In your case, you can refuse to consent to give them what they want (your info), but if you refuse, they aren't going to do business with you - which is their prerogative.
The thing you can do within a day's time is restructure your bank account situation to eliminate the problem. It is the joint account that is causing you this trouble. So close the joint account, and/or open a single account for your mother that she can use for the housing money. This is the easiest way to solve your problem. Good luck.
