New Hampshire now has 30 days to file a governor's request for extradition for him to be returned to the Granite State to face the charge against him.
"The process has begin to have you returned to New Hampshire at their request," Judge David Suntag said.
Robarge is currently being held without bail in Southern State Correctional Facility.
The charge alleges that James Robarge of Saxtons River recklessly caused the death of 42-year-old Kelly Robarge on June 27 in Charlestown, N.H., by inflicting trauma to her body. Investigators said Kelly Robarge died of "homicidal violence by undetermined means."
James Roberge had been jailed at the Southern State Correctional Facility in Springfield on unrelated motor vehicle charges stemming from his arrest on July 2 in Bellows Falls near a medical center. At the time of his arrest, he had been living with his stepfather in Saxtons River.
Fish and Game officers and New England K-9 Search and Rescue found the body of a woman Saturday in a wooded area in Unity, N.H. An autopsy Sunday confirmed the body was that of Kelly Robarge, and the cause of death was homicidal violence by undetermined causes.
On June 27, the day she disappeared, Kelly Robarge had filed for a divorce from Robarge. Shortly after she was reported missing, New Hampshire authorities had said they feared she had suffered serious injury or death.
Assistant Senior Attorney General Susan Morrell said the body of Kelly Robarge was identified Sunday from dental records and a distinctive tattoo.
