Jadhav, a retired Indian Navy officer, was sentenced to death by a Pakistani military court on charges of espionage and terrorism in April 2017.
India first approached the ICJ on May 8, 2017 for the "egregious violation" of the provisions of the Vienna Convention on Consular Relations, 1963 by Pakistan by repeatedly denying it consular access to Jadhav.
A 10-member bench of the ICJ, which was set up after World War II to resolve international disputes, on May 18, 2017 had restrained Pakistan from executing Jadhav till adjudication of the case.
The ICJ has set a timetable for the public hearing in the high-profile case from Febraury 18 to 21 at the Peace Palace in The Hague, the Netherlands.
While India will argue first on February 18, Pakistan will get its chance to make submissions on February 19. Then India will reply on February 20 while Islamabad will make its closing submissions on February 21.
It is expected that the ICJ's decision may be delivered by the summer of 2019.
While maintaining that India remains committed to make all possible efforts to secure and protect the rights of Jadhav, the spokesperson of the Ministry of External Affairs Raveesh Kumar did not make public New Delhi would take at The Hague.
"India will present its case before the court. Since the matter is sub judice it is not appropriate for me to state our position in public. Whatever we have to do, we will do at the court," Kumar said last week in New Delhi in response to a question.
Pakistan's Attorney General Anwar Mansoor would lead the Pakistani delegation at the ICJ while Director General South Asia Mohammad Faisal would lead the Foreign Office side.
Ahead of the hearing, a senior Pakistani official said that his country is committed to implement the decision of the ICJ in the Jadhav case.
"We are fully prepared with our strongest evidence being the valid Indian passport recovered from Commander Jadhav with a Muslim name," the official said.
Both India and Pakistan have already submitted their detailed pleas and responses in the world court.
Pakistan claims that its security forces arrested Jadhav from restive Balochistan province on March 3, 2016 after he reportedly entered from Iran.
However, India maintains that Jadhav was kidnapped from Iran where he had business interests after retiring from the Navy. Jadhav's sentencing had evoked a sharp reaction in India.
Pakistan had rejected India's plea for consular access to Jadhav at the ICJ, claiming that New Delhi wants the access to get the information gathered by its "spy".
However, Pakistan facilitated a meeting of Jadhav with his mother and wife in Islamabad on December 25, 2017.
The hearings at the ICJ is taking place four days after one of the worst terror attacks in Jammu and Kashmir that killed 41 CRPF soldiers. The terror attack happened when a suicide bomber of Pakistan-backed Jaish-e-Mohammad (JeM) blew up an explosive-laden vehicle near a convoy of CRPF buses in Pulwama district on Thursday.
