Serial baby killer Kathleen Megan Folbigg will need to give one month's notice if she wants to give evidence at an inquiry into her convictions.
Folbigg was jailed for at least 25 years in 2003 after she was found guilty of killing her four babies - Caleb, Patrick, Sarah and Laura - in the decade from 1989.
The four children all died aged between 19 days and 19 months.
Folbigg was imprisoned for three counts of murder and one count each of manslaughter and maliciously inflicting grievous bodily harm.
But the NSW government in August 2018 agreed to a judicial review of her case in Sydney.
Hearings will begin on March 18 at the new Lidcombe Coroners Court complex with forensic pathologists and sudden infant death syndrome experts the first to testify followed by a panel of geneticists in mid-April.
Former NSW District Court chief judge Reginald Blanch, who's heading the inquiry, on Friday said April 17 and 18 had been set aside for Folbigg to give evidence but she's yet to advise her lawyers of her position.
"The scope of the inquiry will not include the evidence of Ms Folbigg unless we are notified in writing by March 17 that she does intend to give evidence," he ordered.
The inquiry will focus on medical advances and new research, including on multiple natural infant deaths in the one family.
Folbigg, 51, has asked to watch over the hearings via video link.
