I have had 2 issues with my bank concerning disclosure of personal information. The first was someone I knew calling asking if a check would clear and giving amounts fishing for a balance. The bank would say yes it would clear or no. The second is my ex-wife cashing her child support check every month and the teller writing my balance on a receipt and giving it to her without her even asking. I fund out by telling her I didn't have the money for something and she said "well you had XX dollars in your account what happened to that. This caused a bad situation for me with my kids. Can I sue my bank for doing this? How much can be won in a case like this?
