Wis. Stat. § 895.33: Limitation of surety’s liability.

Any person may limit the amount of liability as a surety upon any bond or other obligation required by law or ordered by any court, judge, municipal judge or public official for any purpose. The amount of the limited liability may be recited in the body of the bond or stated in the justification of the surety. In an action brought upon the bond, no judgment may be recovered against the surety for a sum larger than the amount of the liability stated, together with the proportional share of the costs of the action. In an action brought on the bond, a surety may deposit in court the amount of the liability, whereupon the surety shall be discharged and released from any further liability under the bond.
