Nardini v. Nardini
Supreme Court of Minnesota
414 N.W.2d 184 (1987)
Ralph Nardini (defendant) bought a one-half interest in a business for $2,500 before marrying Marguerite (plaintiff), and shortly after the marriage bought out his partner for $12,500; over 31 years of marriage, the couple transformed the business into a lucrative closely-held corporation, with Ralph managing it as president while Marguerite mostly served as homemaker and community volunteer, occasionally doing bookkeeping. At divorce, the trial court adopted a $350,000 valuation of the business and found Ralph owned one-half outright as separate property (based on his pre-marital investment), treating only the other half as marital property; Marguerite appealed after the court of appeals affirmed.
Whether an increase in the value of separate property that is due to the efforts of one or both spouses during the marriage is properly considered marital property.
