A video confession given by Mr. Jadhav was played before the press briefing by the Ministry.
He watched images of Jadhav's mother Avantika and wife Chetna sitting across a glass screen flicker on the TV set at his home.
"I have been treated with dignity and honour and in a very professional manner by the Pakistani authorities".
According to officials, all arrangements have been made for the meeting between Kulbhushan Jadhav and his wife and mother.
India has also handed over to Pakistan an appeal by Jadhav's mother, initiating a process to get his conviction overturned.
Pakistan had earlier said that Jadhav was not under any threat of immediate execution.
"It was a humanitarian meeting, it was not consular access".
It was the fist time Jadhav was meeting his family since his arrest in March a year ago.
They are seen with Indian Deputy High Commissioner JP Singh, who apparently accompanied the women to the meeting and was allowed to be present at it.
Kulbhushan Jadhav's family reached Islamabad via a commercial flight, and then was transported to the Indian High Commission. It was not known where he had been kept before being transported to the foreign ministry.
On the question why a glass wall was put between them during the meeting, he said it was done "for security reasons". On 20th of this month, Pakistan had issued visa to them to visit Islamabad to meet Jadhav.
India says Jadhav is a former officer of the Indian navy but he rejects the charges against him as baseless, saying he has no connection with the government.
"Kulbhushan travelled between Pakistan, India, Dubai and Thailand for around 17 times" said the official and added that Pakistan had submitted counter-memorial to India's claim before the International Court of Justice (ICJ) on December 13th.
