Can a municipal utility disclose Customer Information, without the customer’s consent, to a title company, bank or real estate broker when the customer premises is being sold or transferred?

Yes. Although there was no specific exception for this when Act 25 was initially enacted, 2013 Wis. Act 134 created a new exception, sec. 196.137(2)(ap), which allows a municipal utility to release customer information in connection with a real estate transaction or appraisal of real property  to a real estate broker or salesperson licensed under ch. 452 or an appraiser certified or licensed under ch. 458.
