Wis. Stat. § 895.34
If any bail bond, recognizance, undertaking or other bond or undertaking given in any civil or criminal action or proceeding, becomes at any time insufficient, the court or judge thereof, municipal judge or any magistrate before whom such action or proceeding is pending, may, upon notice, require the plaintiff or defendant to give a new bond, recognizance or undertaking. Every person becoming surety on any such new bond, recognizance or undertaking is liable from the time the original was given, the same as if he or she had been the original surety. If any person fails to comply with the order made in the case the adverse party is entitled to any order, judgment, remedy or process to which he or she would have been entitled had no bond, recognizance or undertaking been given at any time.

A precondition for this section to apply is that the bond must at one time have been sufficient. Bruer v. Town of Addison, 194 Wis. 2d 617, 534 N.W.2d 634 (Ct. App. 1995).
