The 27-year-old soul diva was found dead in bed on July 23 at her London home.
Probate documents showed on Wednesday that she left behind assets totalling more than 4.25 million pounds, with 2.94 million pounds remaining after debts and taxes.
Since Winehouse did not leave a will, the money will go to her parents. The documents list father Mitch Winehouse as administrator of the singer's estate. Nothing goes to her ex-husband, Blake Fielder-Civil, whom she divorced in 2009.
Winehouse shot to fame with her 2006 album "Back to Black," but struggled for years with drug and alcohol abuse. An inquest found she died of accidental alcohol poisoning.
