Trevor Hamilton's appeal against his conviction for the murder of Strabane pensioner Attracta Harron will be held in February.
Attracta Harron was found in a makeshift grave
His legal team argue the conviction is unsafe. Hamilton has been told he will spend the rest of this life in prison.
He was not in court to hear the date of his appeal, which is expected to last a week.
Mrs Harron, 65, was killed by Hamilton less than four months after he had completed a rape sentence.
She was last seen walking home from morning Mass near Murlog in County Donegal in December 2003.
The body of the mother of five was found months later in a makeshift grave near Hamilton's home. She had been battered to death.
