Service of process
Wis. Stat. § 551.611
in effect(1) Signed consent to service of process. A consent to service of process complying with this section required by this chapter must be signed and filed in the form required by a rule or order under this chapter. A consent appointing the administrator the person’s agent for service of process in a noncriminal action or proceeding against the person, or the person’s successor or personal representative under this chapter or a rule adopted or order issued under this chapter after the consent is filed, has the same force and validity as if the service were made personally on the person filing the consent. A person that has filed a consent complying with this subsection in connection with a previous application for registration or notice filing need not file an additional consent.
(2) Conduct constituting appointment of agent for service. If a person, including a nonresident of this state, engages in an act, practice, or course of business prohibited or made actionable by this chapter or a rule adopted or order issued under this chapter and the person has not filed a consent to service of process under sub. (1), the act, practice, or course of business constitutes the appointment of the administrator as the person’s agent for service of process in a noncriminal action or proceeding against the person or the person’s successor or personal representative.
(3) Procedure for service of process. Service under sub. (1) or (2) may be made by providing a copy of the process to the office of the administrator, but it is not effective unless all of the following apply:
(a) The plaintiff, which may be the administrator, promptly sends notice of the service and a copy of the process, return receipt requested, to the defendant or respondent at the address set forth in the consent to service of process or, if a consent to service of process has not been filed, at the last known address, or takes other reasonable steps to give notice.
(b) The plaintiff files an affidavit of compliance with this subsection in the action or proceeding on or before the return day of the process, if any, or within the time that the court, or the administrator in a proceeding before the administrator, allows.
(4) Service in administrative proceedings or civil actions by administrator. Service pursuant to sub. (3) may be used in a proceeding before the administrator or by the administrator in a civil action in which the administrator is the moving party.
(5) Opportunity to defend. If process is served under sub. (3), the court, or the administrator in a proceeding before the administrator, shall order continuances as are necessary or appropriate to afford the defendant or respondent reasonable opportunity to defend.
