The foster mother and brother of slain Brisbane schoolgirl Tiahleigh Palmer will be sentenced in July for their roles in the 12-year-old's alleged murder.
Julene Thorburn, 54, and son Joshua, 20, have been committed to face a sentencing hearing at Beenleigh District Court on July 27.
The pair weren't present as their indictments were presented to the court on Thursday but have indicated they will plead guilty to charges of perjury and attempting to pervert the course of justice.
Tiahleigh's mother Cindy Palmer was in court, flanked by two supporters.
The body of Tiahleigh was discovered on the banks of the Pimpama River on the northern Gold Coast in November 2015, just days after she was last seen alive.
Julene Thorburn's husband Rick has been charged with the Marsden State High School student's murder.
The pair's younger son Trent has been charged with incest as well as perjury and perverting the course of justice.
