Last week, Rajesh and Nupur Talwar were released from Dasna jail in Ghaziabad after four years of imprisonment. In a much-awaited verdict, they were exonerated by the Allahabad High Court in the sensational double murder case that remains unsolved.
Hemraj worked as a domestic help in the Talwar household. His body was found 48 hours after he was murdered, on the terrace.
Hemraj is survived by his wife, an elderly mother, and two children. They live in Nepal.
Naresh Yadav, who represents the family, said they were waiting to see if the CBI would appeal against the high court's verdict before filing an appeal in the top court.
"We have some like-minded people who have shown interest in representing the family in Supreme Court because Hemraj and his family certainly can't afford the legal charges," he told NDTV.
Mr Singh said there were still a lot of unanswered questions about the case including the identity of the people who killed Arushi and Hemraj.
