Full Text of Section 812.02
Official Notes
Judicial Council Committee Note, 1974: S. 812.02 (1) (a) (intro.) is amended to require the filing of summonses and complaints to make garnishment proceedings comport with other actions under s. 801.02. [Re Order effective Jan. 1, 1976]
Plain-English Summary
Section 812.02 fixes the timing of a garnishment action to specific milestones in the underlying case. Before judgment, a plaintiff can start a garnishment once a summons and complaint have been filed in an action for contract damages, an action on a judgment, or a tort action where a writ of attachment could issue, or once certain contract claims not yet due would independently support attachment. After judgment, a plaintiff can start a garnishment once execution on an in personam judgment is issuable.
The section also handles a defendant who is hard to serve. If the plaintiff cannot obtain personal service, and has filed the summons and the sheriff’s return with the clerk, a judge may allow substituted service on the defendant’s employer, but only if the plaintiff shows the defendant’s current place of employment, that a cause of action exists, and that a reasonable effort was made to achieve personal service. Before taking judgment in that kind of case, the plaintiff must present an affidavit from the employer confirming the defendant received the summons.
Two further limits round out the section. A plaintiff cannot garnish the property of a spouse who was not a defendant in the principal action unless that spouse is also made a defendant in the garnishment action itself. And every garnishment action remains subject to the restriction in Section 806.25, which voids any note’s authorization to confess judgment for the debtor when the note was executed after June 18, 1972.
Finally, the section lets a plaintiff go back to the well: the plaintiff may proceed against other garnishees in the same way, and may proceed against the same garnishee more than once if the plaintiff has reason to believe that garnishee became liable again after the first attempt.
Frequently Asked Questions
When can a plaintiff start a garnishment action before winning the underlying case?
Once a summons and complaint have been filed in a qualifying contract, judgment, or tort action, as Section 812.02(1)(a) describes, a plaintiff may commence a garnishment action even before judgment is entered.
Can garnishment be used to collect a judgment that has already been won?
Yes. Section 812.02(1)(b) allows a plaintiff to commence a garnishment action once execution upon an in personam judgment is issuable.
What if the plaintiff cannot personally serve the defendant?
Section 812.02(2)(b) allows a judge to permit substituted service on the defendant’s employer, but only if the plaintiff has filed the summons and sheriff’s return with the clerk and shows the defendant’s place of employment, that a cause of action exists, and that a reasonable effort at personal service was made.
Can a plaintiff garnish property belonging to a debtor’s spouse who was never sued?
Not unless that spouse is also made a defendant in the garnishment action itself. Section 812.02(2e) bars garnishing a non-defendant spouse’s property otherwise.
Can the same garnishee be sued more than once in connection with the same debtor?
Yes. Section 812.02(3) allows the plaintiff to proceed against the same garnishee more than once if the plaintiff has reason to believe the garnishee subsequently became liable again.
