Michelle Triola (November 13, 1933; Los Angeles, California – October 30, 2009) was an American actress who was mainly notable for unsuccessfully suing Lee Marvin in 1977 after her relationship with him ended. The trial, which brought about the concept of palimony, was widely covered in the media at the time. During this time, she was Michelle Triola Marvin, having legally changed her name to add Lee Marvin's surname to her own. She was represented by attorney Marvin Mitchelson.
Although she and Marvin never married, Triola sought financial compensation similar to that available to spouses under California's alimony and community property laws. The result was the landmark case, Marvin v Marvin, 18 Cal. 3d 660 (1976). The Supreme Court of California held that Triola could proceed with her suit, as it did state a cause of action and the trial court erred in granting judgment to Marvin on the pleadings.
The case went to trial. On April 18, 1979, Judge Arthur K. Marshall ordered Marvin to pay $104,000 to Triola for "rehabilitation purposes", but denied her community property claim for one-half of the $3.6 million which Marvin had earned during their six years of cohabitation. Both sides claimed victory, but in August 1981, the California Court of Appeal ruled that Triola could not show any contract between herself and Marvin to justify any payment to her. As a result, Triola recovered no money from Marvin.
Triola majored in theater arts at UCLA. She was a lounge singer and dancer. She danced in the original 1958 Broadway production of Flower Drum Song, directed by Gene Kelly. Her film acting career consisted of minor roles, including a stand-in in Marvin's 1965 film Ship of Fools and a guest role on the Dick Van Dyke television series Diagnosis Murder.
Triola lived with Dick Van Dyke for 30 years following her breakup with Lee Marvin.
In April 2008 she underwent surgery for the lung cancer. The cancer claimed her life on October 30, 2009 at the home she shared with Van Dyke. She was 75 years old.
