South Africa: Mandela's Ex-wife loses inheritance bid
A High Court dismissed Winnie Madikizela-Mandela's application and ordered her to pay all legal costs.
She argued that the house in Qunu village, where Mr Mandela spent much of his time until his death in 2013, belonged to her under customary law.
Mr Mandela, who became South Africa's first black president in 1994, had bequeathed the home to his family.
The government opposed Ms Madikizela-Mandela's bid to inherit the home after she launched court action in 2014.
Mr Mandela divorced Ms Madikizela-Mandela in 1996 after a 38-year marriage, and left her out of his will.
They were South Africa's most celebrated political couple until their marriage collapsed unexpectedly, some six years after his release from 27 years in prison for fighting apartheid, which legalised discrimination against black people in the country.
Mr Mandela stepped down as president after one term in 1999.
