Wisconsin Notary Public Info - AM I REQUIRED TO KEEP A NOTARIAL LOG BOOK?
Keeping a notarial log book, or journal, is not required in Wisconsin, although you are encouraged to do so. Depending on the amount and types of documents you are handling, recording your notarial acts in a journal may prove useful later if you need to recall specifics of a particular case. If you decide to keep a notarial log book, include items such as date and type of notarial act, names and signatures of persons involved, and numbers from identification cards and driver’s licenses presented.
