With or without a will Winnie was not entitled to anything. Why?
After the divorce was concluded, all the marital bonds between Mandela and Winnie were legally broken and they became free of each other.
The only evidence that was left to show that the two were once married is only the children whom Mandela as a father was obliged to under matrimonial laws...
Winnie will not do anything and she will not go to anybodys court to challenge that will on why she was not given a share of the estate...
...besides, the presence of a safe alone does not signify that there is money inside...
