Wisconsin Statute § 767.511 - Child Support

Wisconsin Statute § 767.56 - Maintenance (Alimony)
Wisconsin courts may award maintenance (alimony) to either spouse based on factors including length of marriage, age, health, earning capacity, and contributions to the other's education or career. Unlike child support, there is no standard formula for calculating maintenance.
