Bankrupt and "a guest of Her Majesty", Salim Mehajer is busy representing himself in court from prison.

After years of unrelenting headlines, thanks to a big wedding in August 2015 and a raft of court cases, the colourful former deputy mayor of Auburn returned to relative obscurity in June after he was sentenced to 11 months in prison for electoral fraud.

But on Wednesday, Mehajer returned to the limelight and the Federal Court in Sydney via audiovisual link from Cooma Correctional Centre.

Dressed in prison greens and surrounded by court documents, Mehajer told Justice Michael Lee he would be "out of custody in three to four months" and would make a fresh bid to overturn his bankruptcy "the moment I'm out of custody".

"When you're no longer a guest of Her Majesty," Justice Michael Lee said.

Mehajer said he would be out of prison by March 21 at the latest, but would be assessed for his suitability for an Intensive Correction Order on January 9.

This would allow him to serve the remainder of his prison sentence in the community, subject to supervision.

Mehajer was sentenced in June this year to a maximum of 21 months behind bars with an 11-month non-parole period after the Local Court found he engaged in a "joint criminal enterprise" with his younger sister Fatima to rig the September 2012 Auburn election that catapulted him into public office.

Ms Schurr said the pair exchanged "numerous" incriminating text messages on July 30, 2012, shortly before the close of the electoral roll. Their tactics included enrolling a number of voters in the Auburn electorate who in fact lived outside its boundaries.

Fatima Mehajer was given a suspended two-month jail sentence and a $500 good behaviour bond after Local Court magistrate Beverley Schurr found she was under pressure to act as she did by virtue of her "position in the family hierarchy".

"I am satisfied that in 2012 the family dynamic was centred around Salim Mehajer," Ms Schurr said in June.

Mehajer, 32, was declared bankrupt by the Federal Circuit Court on March 20 while he was in prison awaiting trial on separate criminal charges.

He has already made one attempt to have the bankruptcy stayed, which was rejected in April by Justice Lee.

Mehajer is embroiled in a number of court disputes including a Federal Court battle with Hong Kong-based financier SC Lowy, who issued two of his property development companies with a statutory demand for $83 million in June last year.

Salim Mehajer and his sister Fatima arrive at Sydney's Downing Centre Local Court ahead of their sentence hearing for crimes related to influencing the 2012 Auburn City Council vote.

On Wednesday, lawyers for SC Lowy sought an order from the Federal Court preventing Mehajer bringing a range of court cases in his own name, arguing such proceedings could only be brought by his trustee in bankruptcy. The trustee shares this view.

Sydney barrister Alec Leopold, SC, for SC Lowy, said his client "should not be exposed for a single day longer to the mounting costs [and] the vexation" of proceedings being launched by Mehajer.

The court heard a law firm acting for SC Lowy had already incurred professional costs totalling more than $300,000 as a result of two court cases brought by Mehajer, now rolled into one in the Federal Court.

Justice Lee gave Mehajer an opportunity to seek legal advice over the next month on proposed orders sought by SC Lowy.

Those orders would not prevent the former deputy mayor making an application in the future to annul his bankruptcy and to pursue further legal action in his own name if an annulment was granted.

"The fact is, he's in Cooma. It's the 19th of December," Justice Lee told the parties.

"I don't think there's any risk of him doing anything between now and the end of January."
