Showbiz Spy reports that the ailing 73-year-old actor has been persuaded by his older children and advisors.
"Over the past few weeks [Hopper] has stated to me that he has been 'pressured' by his advisers and adult children from other relationships to file for dissolution of our marriage," Victoria Hopper said.
She added: "[He] has told me that he does not want to divorce. [He] has told me that other people are insisting that he takes care of them upon his death.
"I believe that he is more often than not incapable of handling his legal and financial affairs. His adult children are attending his legal appointments and have told me they 'read everything'."
