Court records show the "Medium" star requested and was granted a dismissal of the couple's divorce case, which she filed in January.
The one-page dismissal didn't indicate a reason for the 41-year-old actress seeking a dismissal. Records show her request was filed on Tuesday and approved on Thursday.
The couple was married in May 2006 and have a daughter, Harlow Olivia Calliope Jane.
Arquette won an Emmy Award in 2005 for her portrayal of a paranormal expert on "Medium." The 40-year-old Jane appeared in the 2007 film "The Mist" and 2004's "The Punisher," and he stars in the new HBO series "Hung."
