Wisconsin authorized RON in 2020. General remote online notarization (Wis. Stat. §140.145) applies to ordinary notarial acts. For estate-planning instruments specifically, 2023 Wis. Act 130 (effective March 21, 2024) created Wis. Stat. §140.147, which authorizes a notarial act performed for a remotely located individual signing a will, codicil, trust instrument, certification of trust, power of attorney for finances, power of attorney for health care, marital property agreement, nonprobate transfer (Wis. Stat. §§705.10, 705.15, 705.18, 766.58(3)(f)), declaration to health care professionals, authorization for final disposition, HIPAA authorization, instrument exercising a power of appointment, or instrument of disclaimer. The remote notarial act is distinct from the supervised remote witnessing of the underlying will, finance POA, HC POA, declaration to health care professionals, or final-disposition authorization, which is governed by Wis. Stat. §§853.03(2)(c), 244.05(3), 155.10(3), 154.03(3), and 154.30(8m) respectively (also created by Act 130) and requires a Wisconsin-licensed supervising attorney plus an affidavit of compliance. Both parties must be physically located in Wisconsin during the 2-way audiovisual session. Even with Act 130's remote pathway available, third-party acceptance (banks, title companies, registers of deeds) routinely prefers in-person physical-presence execution.
