Trattles v. Trattles
In Trattles v. Trattles, 126 Wis. 2d 219, 376 N.W.2d 379 (Ct. App. 1985), the Court concluded that a spouse's use of the proceeds from gifts from her father to pay for furnishings, repairs, maintenance and improvements for the jointly owned home, and to make mortgage payments demonstrated the spouse's donative intent. Trattles, 126 Wis. 2d at 224.
The Court held that when a spouse makes "a conscious and presumably informed decision to alter the existing manner in which his or her solely owned exempt property is held ... such property no longer retains its character as separate property, but rather becomes part of the marital estate subject to division under sec. 767.255, Stats." 126 Wis. 2d at 227.
