Victoria Hopper wrote that her husband's medical and mental state have become unpredictable as he battles prostate cancer, according to the documents filed Monday in Los Angeles Superior Court.
The 42-year-old is seeking full custody of the couple's 6-year-old daughter. She is also asking a judge to allow Dennis Hopper supervised visits with his daughter for up to an hour per day, depending on his health. Her filing seeks strict guidelines, including a requirement that Hopper remove all guns from the family's house and refrain from smoking medicinal marijuana before the visits.
"I do not believe that petitioner is capable of taking care of himself or his legal and financial affairs," Victoria Hopper's declaration said. "Therefore, I do not believe Petitioner is capable of making sound decisions in the best interests of our daughter."
Hopper's manager, Sam Maydew, did not return repeated calls and e-mails seeking comment on Monday and Tuesday.
Many of the filing's details were first reported by the Web site The Daily Beast.
In her filing, Victoria Hopper claims her husband told her that he didn't want to end the marriage, but he filed for divorce on Jan. 14 because "other people are insisting that he take care of them upon his death."
The "Easy Rider" star is asking for joint custody of their daughter and that he make spousal support payments. Both have cited irreconcilable differences for the breakup.
He was first diagnosed with prostate cancer a decade ago, but it returned late last year. He started chemotherapy treatments earlier this month, the filing stated.
Victoria Hopper is asking a judge to protect her and her daughter's stake in a $1 million life insurance policy and a college fund. She claims the divorce is a means to cut her out of Hopper's estate and wants a judge to nullify the couple's prenuptial agreement.
According to Victoria Hopper's filing, Dennis Hopper amended his estate plan in October in violation of the prenup agreement.
She is also asking a judge to grant her access to certain portions of the compound where the couple and Hopper's two adult children live.
