A funeral service for Nóra Quoirin will take place in Northern Ireland early next week.
It is understood a service will be held for friends and family in Belfast.
The teenager’s body was found last month more than 2km from the jungle resort of Dusun, where she had been staying with her family.
Hundreds of people were involved in the search operation.
The teenager, who was born with the brain defect holoprosencephaly and was described by her family as "vulnerable", disappeared on 4 August.
Her family believe she was abducted, insisting she would not have wandered off by herself.
However, police in Malaysia said they have so far found no evidence of abduction or kidnapping.
A post-mortem examination revealed Nóra died from internal bleeding probably caused by hunger and stress.
Nóra lived in London and was the daughter of French-Irish parents Sebastien and Meabh Quoirin.
