Confirming paternity would mean the 58-year-old former World Cup winner and paternity-suit veteran has fathered eight children officially.
Lawyer Matias Morla told Argentina's Channel 13 television on Friday that he speaks with his client's Cuban children, who were born to two different women.
"Maradona has three children in Cuba, with whom he's in contact," Morla said, adding Maradona would not contest the latest paternity suit in Cuba, where the footballer intermittently underwent treatment for cocaine addiction between 2000-2005.
Asked if Maradona had legally recognised his children on the island, Morla said: "To date, no. But he is going to take care of what he has to do."
