An inquest into the death of Yousef Makki is due to be held next year.
Yousef, 17, a Manchester Grammar School pupil, died from a stab wound to his heart in Hale Barns in March 2019.
At a pre inquest review hearing on Friday, it was confirmed that a full hearing into his death will now take place at South Manchester Coroners' Court next March.
Last year, Joshua Molnar, from Hale, was found not guilty of murder and manslaughter following a trial at Manchester Crown Court.
He told the jury Yousef pulled a knife first and said he acted in self-defence.
The 18-year-old admitted possessing the knife which inflicted the fatal injury and lying to police at the scene and was sentenced to a 16-month detention and training order.
Adam Chowdhary, 18, of Hale Barns, was handed a four-month detention and training order after he admitted possessing a flick-knife.
He was acquitted of perverting the course of justice and conspiracy to rob.
The pair both have 'interested party' status in the inquest, as do Yousef's family, Greater Manchester Police, Cheshire Constabulary and the Independent Office for Police Conduct.
The court heard that due to the coronavirus pandemic, there is a 'backlog' of cases, and as such, the full inquest will be heard early next year.
The hearing has been listed to last for two weeks and will be heard by Coroner Alison Mutch alone, without a jury.
It was agreed that it will start on March 15 2021, in line with the wishes of Yousef's family, who preferred for it not to coincide with the anniversary of his death, on March 2.
There will also be a further pre inquest review hearing held in October.
Following the inquest, Yousef's sister Jade Akoum issued a statement on behalf of the family.
She explained that her mum, Debbie Makki who died last month aged just 55, had wanted a full inquest into her son's death.
Jade said: "We are grateful to the coroner for resuming the inquest into Yousef's death.
"My mum was anxious for an inquest to take place in order to bring some closure and we are deeply saddened that she was not there to hear today's decision.
"We remember and mourn both her and Yousef today and we look forward to the inquest bringing us some desperately needed answers."
