Stuart Hazell, the man accused of murdering 12-year-old Tia Sharp, will appear at the Old Bailey on Friday.
The 37-year-old is due to appear in Court One by a prison videolink for the plea and case management hearing.
Hazell is due to go on trial at the same court on May 7 accused of murdering Tia, the granddaughter of his partner Christine Sharp, 46.
Hazell, from New Addington, south London, is charged with murdering the schoolgirl between August 2 and 11 last year.
Tia's body was found in the loft at Christine Sharp's home in New Addington a week after she was reported missing, and following searches by police and members of the public.
