I thought i read somewhere in Reg E that is was not permissible to charge a fee for processing an error resolution claim. I have searched and could not locate. Thoughts?

The consumer's liability for unauthorized transactions is governed by 1005.6.

See the commentary to section 1005.11

3. Charges for error resolution. If a billing error occurred, whether as alleged or in a different amount or manner, the financial institution may not impose a charge related to any aspect of the error-resolution process (including charges for documentation or investigation). Since the Act grants the consumer error-resolution rights, the institution should avoid any chilling effect on the good-faith assertion of errors that might result if charges are assessed when no billing error has occurred.

Thank you all!
