Correctional Services spokesman Manelisi Wolela has denied allegations that student leader Mcebo Dla.
Stepgrandmother Sarah Ndlovu says the children of the late king of Shangaan disco, Paul Ndlovu, are not entitled to inherit from his estate.
But Ndlovu's two stepgrandchildren claim she is trying to swindle them out of their inheritance.
Ndlovu, who was married to the disco king's father, is believed to have laid a claim with the singer's recording company, Gallo Records, stating that the children had no claims to his estate.
According to the company, the monetary value of the estate amounts to less than R100000.
Sowetan has established that Ndlovu sent a letter of complaint to the singer's recording company in which she questioned the procedure in awarding the children as heirs to the estate.
Ndlovu accused the company of failing to refer to documents, in the possession of Sowetan , which appointed the late singer's father and mother executors of his estate.
The documents also state that Ndlovu be nominated as the heir because she was married to the singer's father at the time.
Ndlovu's letter stated that the documents were in a file held by the magistrate at Lulekani in Limpopo.
Ndlovu's lawyer, Topsy Thete, said yesterday they want the matter to be adjudicated by a magistrate or judge.
Meanwhile, Leanne Billet, Gallo's legal adviser confirmed receipt of Ndlovu's letter.
"We are opposing the letter through the courts because we believe there was an error in relation to the file and it is our view that the children must inherit from the estate," Billet said.
