Hopper sought an order Thursday barring his wife, Victoria, from contacting or communicating with the "Easy Rider" star and his adult children.
The actor filed for divorce in January and both sides have cited irreconcilable differences for the breakup. Victoria Hopper claimed in court papers that the actor smoked marijuana around their daughter and his illness had left him unable to make sound decisions.
Hopper denied those claims in court filings Thursday.
