LOS ANGELES -- The "Easy Rider" may have ridden off into the sunset but the battle for the riches Dennis Hopper left behind appears to be heading for a rough road. Iconic actor Dennis Hopper, who died Saturday after a long bout with cancer, had been seeking to divorce his wife of 14 years, Victoria Duffy. Now, say reports, she plans to battle for a hefty share of his riches.

According to several sources, the couple's prenuptial agreement grants Duffy a part of Hopper's estate only if the couple was married and living together at the time of his death. She plans to argue that even though they lived in separate houses at the time of his death, they were "living together" because her house was on his property, TMZ reported.

Hopper wanted to deny his estranged wife the 25 percent of his estate and $250,000 in life insurance money promised in their prenup. The divorce, which he initiated in January, was not final when he died. But it had grown plenty nasty.

In March, Hopper claimed in a court affidavit that Duffy stole "valuable works of art" from him, including a portrait of the actor by Andy Warhol and sculptures by Robert Graham and Brit wit Banksy. He valued the works at a combined $1.5 million. Hopper claimed Duffy "surreptitiously removed from my home very valuable personal property while I was extremely ill, refused to tell me where the property was when I asked her, and then left town."

The battle now moves to probate court.
