The man convicted of murdering 13-year-old Cornish girl Caroline Dickinson is to have his appeal heard next summer.
Montes was convicted of Caroline's 1996 murder
Francisco Arce Montes was jailed for 30 years in June with a recommendation he should serve at least 20 for killing Caroline in France in 1996.
The appeal of the 54-year-old Spanish waiter from Gijon will be heard next May or June in St Brieuc, Brittany.
Caroline's family said they were disappointed that Montes chose to appeal following his trial.
Caroline was attacked, raped and murdered by Montes in the early hours of 18 July 1996 as she slept on the floor of a hostel dormitory in Pleine Fougeres, Brittany.
She was among 41 youngsters from Launceston Community College on an activity holiday.
Montes evaded capture until US police arrested him over a similar attack on a woman in Florida in April 2001.
He was extradited to France and jailed after a trial in Rennes, Brittany. Caroline's father, John, 48, from Bodmin; her 46-year-old mother, Sue, from Launceston, and her 19-year-old sister Jenny sat through the trial.
The court, in a civil hearing, also ordered that Caroline's parents be paid £24,100 each, with an additional £17,217 paid to Jenny.

It is understood that the French Chief Prosecutor will visit Montes in prison early in the New Year to ensure that he still wishes the appeal to continue.
Montes' intention to appeal was revealed shortly after the trial. Members of Caroline's family said in a statement at the time they were angry and very upset to learn of the appeal and that their wish to begin the process of rebuilding our lives was "yet again, on hold".
Caroline's family said on Friday: "We are still very disappointed that Montes chose to appeal following his trial.
"However, we stand by what we said at the time that we will attend the appeal hearing whenever it is held."
