Banks are strictly following guidelines when setting up a new bank account or changing signers.  When you are changing the signers on the bank statement, you should take

* All current signers and all new signers to the bank with photo ID
* A copy of your red stamped bylaws
* Minutes of the meeting where the new board was elected
You may also take a copy of one the letters below edited with your PTA information

Banks are not trying to hinder the work of PTA, they are trying to protect the money that is in the account for your membership.
