As reported here Dennis Hopper's assistant has stated that his wife has tried to kill him and has looted his estate of millions of dollars already as he is seriously ill and dying of cancer. They are currently going through a bitter contested divorce dispute. During the litigation the assistant is helping his side and discussing what she has observed. Dennis Hopper was in the movie Easy Rider and many others.
Fortunately it appears that he had properly planned in advance with a prenuptial agreement. The terms can be read by clicking here. He keeps all of his real estate, artwork, bank accounts and all his property pursuant to its terms with the exception that if they were both married and living together at the time of his death his wife Victoria would receive a life insurance policy worth $250,000 and 25% of everything in his will and trust which apparently would have amounted to around $6.25 million. They are not living together so pursuant to the terms of the pre nup unless she challenges it she should not get anything.
In Florida absent the pre nup she would have all the rights of a spouse if the estate had not completed and he had passed away even if he wanted her to have nothing and was just days away from the divorcing going through. However his estate may seek to invoke the slayer statute depending on his manner of death and if she had taken intentional and illegal actions that brought about his death she could be barred from receiving anything from his estate.
