Judge Martín Bava says Mr Macri has violated the country’s intelligence laws by demanding a dossier on the victims’ families.
They accuse the Navy of negligence.
Mr Macri, who was president in 2015-19 and is now an opposition leader, says the charges are politically motivated.
“I did not spy on anyone, I never ordered [anyone] in my government to spy on anyone,” he said earlier this month.
The victims’ relatives say they have been followed, intimidated, and had their phones tapped after accusing the Argentine Navy of negligence in the maintenance of the Ara San Juan submarine.
The wreckage was found only a year later off the coast of Patagonia.
Experts believe the submarine imploded and sank after a technical fault.
