Sign by video with our New Jersey notary while you're in Wisconsin, 7 AM to 9 PM Eastern, seven days a week, by appointment. New Jersey law lets a New Jersey notary notarize for a signer located in another state (N.J.S.A. 52:7-10.10). How Wisconsin treats it: Wisconsin's Department of Financial Institutions says notarial acts performed by notaries of other states have the same effect under Wisconsin law as if an in-state notary performed them.
