(CNN) — The feud between a grandson and relatives of Nelson Mandela continued Saturday as the grandson plans to file a complaint accusing the family's lawyer of misleading the courts on Mandela's precarious health, according to a report in the South African Press Association.
The association quoted Gary Jansen, the attorney of grandson Mandla Mandela. Nelson Mandela, 94, the anti-apartheid icon who was South Africa's first black president, continues to fight for his life while on kidney dialysis.
"We still need to formalize the complaint but certainly on my client's side he has instructed me to lay a complaint both to the Law Society and the bar council," Jansen said Saturday.
Further details on the grandson's accusation weren't immediately available. The family attorney couldn't be immediately reached for comment.
A bitter family dispute over the burial of Mandela's three deceased children has been competing for headlines with worldwide concerns about Mandela's tenuous condition. Mandela is on life support, but a source with direct knowledge of his situation said Friday that Mandela isn't in a vegetative state, rebutting reports to the contrary.
Mandela has been hospitalized for nearly a month for a recurring lung infection.
The burial dispute landed in court, pitting 16 members of Mandela's family against his grandson, Nkosi Zwelivelile Mandela, also known as Mandla, over where the three deceased children of Mandela should be buried.
Two years ago, Mandla Mandela exhumed the three bodies from the family graveyard in Qunu -- Nelson Mandela's boyhood home -- and reburied them in Mvezo, the birthplace of Nelson Mandela.
On Wednesday, Mandla Mandela lost his case in court, and the three bodies were reburied Thursday in the family graveyard.
But the dispute brought a public chiding from another hero of the anti-apartheid cause, retired Archbishop Desmond Tutu.
In a statement carried by the South African Press Association late Thursday, Tutu urged the family not to "besmirch" Mandela's name in what could be his last days.
Investigators have been gathering evidence against Mandla Mandela in a "grave tampering" case and expect to hand it to a senior prosecutor next week, Mthatha police said Friday, according to the South African Press Association.
