Wisconsin Postnuptial Agreement Overview

Wisconsin is a community property state (called marital property under the Wisconsin Marital Property Act) that recognizes postnuptial agreements under Wisconsin Statutes Chapter 766. The Marital Property Act provides a comprehensive framework for marital property agreements that allows spouses to modify their property rights.

Under Wisconsin's marital property system (Wis. Stat. Section 766.001 et seq.), property acquired during marriage is presumed to be marital property belonging equally to both spouses. Wisconsin Statutes Section 766.58 specifically authorizes marital property agreements that can reclassify property, define property divisions, and establish terms for financial matters.

Wisconsin courts evaluate postnuptial agreements under the Marital Property Act framework and the fiduciary duty standard between spouses. The statute provides specific requirements for marital property agreements, giving Wisconsin a clearer framework than many states. Both spouses should have independent counsel.
