Forrest Gump star Wright Penn, 44, filed for legal separation in August 2009, putting an end to the couple's 13-year on/off marriage.
The stars recently reached a private agreement concerning spousal and child support for their 17-year-old son Hopper Jack, who is their only remaining dependant child, according to court papers filed in Marin County, California on 22 July (10).
The Penns are also parents to a daughter, Dylan, 19, reports People.com.
The stars' marriage troubles have been in and out of the press - they first started divorce proceedings in December 2007, only to call it off four months later.
The Milk actor, 49, then filed to end their union in April 2009 before reuniting a month later (May09). They split for the last time shortly afterwards.
