"We have organised this bike rally and human chain to send a message to the family of Jadhav who is in custody of Pakistani government since his arrest past year".
They will arrive by a commercial flight on December 25 and leave the same day.
Pakistan's Foreign Office spokesperson Mohammad Faisal confirmed this in a tweet late last evening.
Jadhav, 47, was sentenced to death by a military court in April on the charges of espionage and terrorism.
"The mother and wife of Jadhav will be able to see and talk to him but there will be a partition between them for security reasons", said the official, who is involved in making arrangements for the meeting. India's deputy high commissioner J P Singh will accompany the visitors to the meeting.
On December 17, 2017, Pakistan had said that the visa applications of Jadhav's family had been received and were being "processed".More news: Comcast, AT&T trickle down $1K bonuses to employees after corporate tax bonanza
The mother and wife of Jadhav were being provided with a meeting with him in the light of "Islamic traditions and based on purely humanitarian grounds", he had said.
New Delhi has repeatedly sought access to the convicted spy but Islamabad denied the permission on the ground that consular access in cases related to spies was not applicable. Jadhav will be brought to the ministry for the meeting, and India wants Pakistan to bar journalists from speaking with the family members for security reasons.
Pakistan says Jadhav was working for the Indian spy agency, RAW. Pakistan says its security forces arrested Jadhav, alias Hussein Mubarak Patel, from its restive Balochistan province on March 3 previous year after he entered the country from Iran.
After Pathankot attack, the ties between the two countries had strained.
The mother and wife of the arrested Indian spy will arrive in Pakistan on Monday and will return after the meeting.
