Mother Noemi Kondacs gives bizarre reason why she doesn't want a lawyer after she was charged with murdering her infant son Rhuan with her husband

A woman jointly charged with her husband with the murder of their infant son northwest of Brisbane has bizarrely claimed she will not be getting a lawyer because she trusts 'in the Lord' to give her 'the words to say'.

Murder indictments were presented against Noemi Kondacs and her husband Reinhardt Albert Bosch in the Supreme Court in Brisbane on Thursday.

The couple are accused of murdering their infant son Rhuan at their home in Yugar on November 3, 2022.

Ms Kondacs, from Stuttgart in Germany, has refused to seek legal representation since she was first charged.

'For a charge of this seriousness, it would be in your interests to get some legal advice at some stage,' Supreme Court Justice Peter Callaghan told Ms Kondacs.

'I'm intrigued ... because for a charge of this seriousness I wonder why you wouldn't get legal advice?'

Asked if she wanted to speak to anyone about legal representation, Ms Kondacs declined.

'I just trust in the Lord to give me the words to say,' she told the court.

Justice Callaghan urged her to consider some advice, even if it was about how the legal system worked, to ensure her best interests could be looked after.

Police allege Mr Bosch and Ms Kondacs prayed over Rhuan's injured body before phoning an ambulance on the day of his alleged murder.

It is further alleged Rhuan had 'visible' injuries when police discovered the 'confronting' scene.

Ms Kondacs is also facing a single charge of failing to provide the necessaries of life.

Mr Bosch was committed to stand trial in the Supreme Court on charges of murder, torture and assault occasioning actual bodily harm while armed with an offensive instrument in October last year.

William Sun, acting for Mr Bosch, on Thursday said his office would benefit from making submissions on their client's torture charge.

Mr Bosch and Ms Kondacs have not yet entered pleas to the charges.

Both cases will be mentioned at court again on May 9.

Dates for Mr Bosch and Ms Kondacs' trials have not been set.
