Cilla Black's estate in the UK is worth more than £15.2 million, according to her will.
The singer left her fortune to her sons following her death last August.
She also left £20,000 to Penelope Walker, understood to have been her long-standing housekeeper.
Black died of a stroke on August 1 after falling and hitting her head at her Spanish villa.
The 72-year-old was sunbathing when she lost her balance, fell and hit her head, which knocked her unconscious.
Beneficiaries of Black's £15,217,454 estate are listed in the will as being her children. She had three sons: Robert, Ben and Jack Willis.
Her husband Bobby Willis died of cancer in 1999 and she never remarried.
Born Priscilla Maria Veronica White in Liverpool, Black had spoken of how she would die happy if she were to pass away before any illness could rob her of being able to enjoy life.
She became one of the nation's favourite entertainers after transforming herself from a successful singer in the 1960s to the front woman on shows such as Blind Date and Surprise! Surprise!
