Salim​ Mehajer's​ estranged wife Aysha​ holds the reins to key parts of his business empire while a court order prevents him from contacting or approaching her, company records reveal.

On Wednesday the Downing Centre Local Court extended an urgent 28-day Apprehended Violence Order made by police against Mr Mehajer on behalf of his wife.

The order prevents Mr Mehajer from approaching or contacting his wife of one year, who has reverted to using her maiden name Aysha Amelia Learmonth, and from going within 50 metres of her home or workplace.

The conditions may restrict the property developer-turned-politician's ability to run his multimillion-dollar business empire, which has been hit with a series of legal disputes over allegedly unpaid debts including tax bills.
