Winehouse married Fielder-Civil in Miami in 2007, but he was arrested six months later over an assault and sent to jail.
He filed for divorce earlier this year on the grounds of the soul diva's infidelity.
Divorce papers filed with the court stated that Fielder-Civil found living with Winehouse "intolerable." Winehouse acknowledged adultery and said she would not contest the divorce.
Winehouse shot to stardom with the multi-Grammy-winning album "Back to Black" in 2006. But her music has been overshadowed by reports of drug use, run-ins with the law and her tempestuous marriage.
The singer has spent the last few months on the Caribbean island of St. Lucia. She is due to stand trial in London next week on charges of assaulting a fan.
