Senior judges have confirmed they will hear Barry McCarney's bid to overturn his conviction in April.
McCarney, 34, is serving a minimum 25-year prison sentence after being unanimously found guilty of the murder of Millie.
The toddler died from severe injuries to the brain in December 2009 following her admission to hospital in Enniskillen, Co Fermanagh.
She had sustained multiple fractured ribs, heavy bruising and a fatal blow to the head.
McCarney, formerly of Trillick, Co Tyrone, began a relationship with Millie's mother, Rachael, and moved into the family home in Enniskillen months before her death.
In December 2012 a jury reached a verdict that he had murdered the child.
He was also convicted of sexual assault and causing grievous bodily harm to her. Rachael Martin was acquitted at trial of allowing her daughter's death and cruelty through wilful neglect.
In the Court of Appeal on Friday, counsel for McCarney disclosed part of their challenge to his conviction centres on the Domestic Crime and Victims Act 2004.
Donal Sayers said: "There's a major structural issue about that legislation."
He also detailed efforts to obtain transcripts of evidence given at trial by his client's co-accused.
Listing the case for hearing on 1 April, Lord Chief Justice Sir Declan Morgan predicted the issues involved could be dealt with in two days.
