A staff member from the Indian High Commission will also be present at the meeting, Foreign Office spokesman Mohammad Faisal told the media.
"Pakistan has agreed to facilitate the visit of mother and wife of Kulbhushan Jadhav and assured us of their safety, security and freedom of movement in Pakistan".
A sovereign guarantee from Pakistan government was sought to ensure safety and security of both.
Meanwhile, External Affairs Minister Sushma Swaraj took to Twitter saying, "Govt of Pakistan has conveyed that they will give visa to mother and wife of #KulbhushanJadhav".
Pakistan claims its security forces arrested him from restive Balochistan province on 3 March a year ago after he reportedly entered from Iran. As India took the case to International Court of Justice (ICJ) in May, Pakistan even told the United Nations court that "Pakistan doesn't see the merit in a state which sends a spy and is seeking access to a tool for terror".
Jadhav was arrested by Pakistan on charges of espionage.
Pakistan has repeatedly denied India consular access to Jadhav on the ground that it was not applicable in cases related to spies. Jadhav's sentencing had evoked a sharp reaction in India.
This had exacerbated ties between India and Pakistan - already frayed after a series of terrorist attacks on military installations in Pathankot, Uri and Nagrota.
Pakistan had earlier offered India a meeting between the convicted spy and his wife on humanitarian grounds.
