Andre Semikhodski, a London-based DNA expert, will give his opinion on forensic documents provided by the CBI to the defence.
The doctor has also written a letter to the court stating that he would be in Ukraine from September 10 to September 11 and was ready to depose before the court.
"Accepting our application, the court has fixed September 16 for recording Dr Semikhodsi's statements," said Manoj Sisodia, counsel for Rajesh and Nupur Talwar.
