The 88-year-old leader, if he appears, would be quizzed by the counsel for 32-year-old Rohit Shekhar and his mother Ujjawala Sharma in the case which was filed in 2008.
S M Chopra, a former Additional District judge who has been appointed as the local commissioner by the High Court to record evidence on a day-to-day basis, has fixed August 21 and 21 as dates for the examination of Tiwari in the case.
The counsel for Tiwari had indicated that he may file an application before the court seeking an order to conduct his cross-examination outside Delhi.
The Congress leader has so far refused to settle the lawsuit out of court through mediation saying there was a possibility that even the medical evidence was not hundred percent accurate.
The high court had on July 27 last year read out the DNA report in the case as per which Tiwari was shown as Shekhar's biological father.
Tiwari's pleas had been objected to by Rohit who had filed the paternity suit in 2008, claiming the veteran Congress leader to be his biological father. Tiwari had refuted his claim.
