LOS ANGELES -- (AP) -- Michelle Triola Marvin, who fought a landmark ``palimony'' case against her former lover, actor Lee Marvin, has died. She was 76.

A family spokesman says Marvin died Friday morning of lung cancer at the Malibu home she shared with partner actor Dick Van Dyke.

Marvin lived with Lee Marvin for six years and took his name. They broke up in 1970. Nine years later she sued for nearly $2 million, even though she had no alimony rights because the couple never married. Her lawyer dubbed the request ``palimony'' and the name stuck.

She eventually won $104,000, although the award was overturned.

The case set a precedent that allowed unmarried partners to sue for financial support.
