Madikizela-Mandela lodges papers for Madiba's estate
Madikizela-Mandela has previously said she should have Madiba's home in Qunu.
Madikizela-Mandela was left out of Madiba's will as he said his property should be managed by his trust for his children.
She has previously said she would make a claim on Mandela's Qunu home.
Notyesi says he has lodged papers in court relating to the estate of the former president.
But he says that doesn't mean Madikizela-Mandela is necessarily legally challenging Madiba's estate.
In his last will and testament Mandela said he wanted his wife Graca Machel to have half of his belongings, but she then waived her rights to those assets.
Madikizela-Mandela has previously said she should have Madiba's home in Qunu because the cattle on the property were being left to starve.
