Probate documents show Winehouse left behind assets totaling more than $6.7 million, with $4.66 million remaining after debts and taxes.
Because Winehouse did not prepare a will, the money will go to her parents. Her father, Mitch Winehouse, is listed as the administrator of her estate. Nothing will go to Winehouse's ex-husband, Blake Fielder-Civil, whom she divorced in 2009.
Winehouse died of accidental alcohol poisoning at her London home in July 2011. The soul singer shot to fame with her 2006 album "Back to Black," but struggled for years with drug and alcohol abuse.
