Sources said that a draft of Pakistan's reply has been prepared, which would be submitted by the Foreign Office's Director India, Fariha Bugti, to the ICJ. The suspect was said to be an officer of the Indian navy working for the spy agency to destabilize Pakistan.
The worldwide court will now decide whether to take the case forward for hearing or ask the parties (Pakistan and India) to submit more documents.
The ICJ, a world court that sits at the Peace Palace in The Hague, is seized with an Indian complaint on the conviction of the Indian spy and had set a deadline of Dec 13 by which Pakistan had to submit its counter-pleadings or counter memorial against the Indian claims.
Pakistan claims its security forces arrested Jadhav alias Hussein Mubarak Patel from restive Balochistan province on March 3 past year after he reportedly entered from Iran. Jadhav was later given the death sentence by a military tribunal.
Army Chief General Qamar Javed Bajwa ratified the sentencing by the army tribunal.
Jadhav is not an ordinary person but was serving a serving officer of the Indian Navy.
"Pakistan has informed India that it is ready to allow the visit of the mother of Commander Jadhav, along with his wife", said Spokesperson Dr Muhammad Faisal at a weekly news briefing.
Pakistan stuck to its version that Jadhav was on active duty as a spy and sent by India on a "special mission". The dossier contained Jadhav's confessional statement and related documents and evidence of the Indian interference in Balochistan.
Last week, Islamabad said it would allow Mr. Jadhav's wife and mother to meet him on December 25.
India had several times tried to arrange a meeting of Jadhav with his family members.
The dossier also included evidence of contacts of Indian intelligence officials, working under diplomatic cover at the Indian High Commission in Islamabad, with terrorists. Minister of External Affairs Sushma Swaraj had even written a "personal letter" to the advisor to the prime minister of Pakistan on national security and foreign affairs Sartaj Aziz, asking for approval of Jadhav's mother visa application of so that she may travel to Pakistan.
