Is there a WI statute that requires a bank to provide documentation that a loan has been paid off? Currently I believe we send a copy of the note indicating that it's been paid in full. If there is a requirement, we are wondering if this can be sent electronically to the customer rather than by snail mail.

If there is a requirement to send them a notice or paid note, then it would have to be sent through a valid E-Sign system to send it electronically.
