How Wisconsin Divides Property

Wisconsin is one of nine community property states, though it uses the term “marital property” rather than community property. Under the Wisconsin Marital Property Act, income earned and assets acquired during marriage belong equally to both spouses. Wisconsin extends marital property rules to registered domestic partnerships. A prenup (called a “marital property agreement” in Wisconsin) can classify specific property as individual rather than marital, and modify the default equal-division rules.

How Clause Helps

Your Clause prenup explicitly defines which property is separate and which is marital, overriding Wisconsin's default 50/50 community property split with terms you both agree on.
