Separating for the second time in as many years, the "Medium" actress first filed for divorced from her "Hung" hubby in January 2009, citing "irreconcilable differences," but the pair reunited just weeks later and hosted a party at their Los Angeles home together.
Reports tell that Miss Arquette asked for her petition to be dismissed in July 2009 after the couple decided to work at their marriage, but the efforts have been of no avail - as they have split again.
representative for the pair says, "The split is completely amicable and their prime focus is their daughter. They ask that their privacy be respected at this time."
Thomas and Patricia were married back in 2006 and share a seven-year-old daughter named Harlow Olivia Calliope.
