Lauren Cranston, the sister of alleged tax fraud mastermind Adam Cranston, will undergo an examination of her finances today in the Supreme Court.
The 24-year-old and her brother are the children of deputy commissioner of the Australian Tax Office (ATO), Michael Cranston.
Ms Cranston is one of 10 people charged over an alleged conspiracy to defraud the Tax Office of $130 million.
That figure has been revised down from an earlier $165 million amount by the Australian Federal Police (AFP).
On Friday, Ms Cranston’s lawyer argued it would be difficult for her to undergo the examination because she is eight months pregnant.
He also said she “didn’t have a cent to rub together”.
However, it has been decided she would undergo the examination today.
It will take place in a closed court.
The Australian Federal Police has launched a proceeds of crime civil suit against at least 66 people and companies connected to the alleged multi-million-dollar fraud, in an attempt to retrieve some of the money.
Michael Cranston is due to be examined on Wednesday.
He has been charged with abusing his position as a public official and has been stood aside from his position at the tax office.

It is alleged he attempted to access restricted information on behalf of his son Adam.
Police do not allege he was part of the conspiracy.
The AFP said the conspirators allegedly used a complex series of companies to defraud the Commonwealth.
It has been described as the most significant while collar swindle in Australia’s history.
On May 17, police investigating the alleged conspiracy conducted 28 raids across Sydney.
