Billionaire Visy heiress Heloise Pratt alleges her ex-husband, prominent investor Alex Waislitz, falsified board meeting records to pay out money from their company to himself and his foundation over her.

The stoush between the one-time couple played in private for months before an escalation to the Victorian Supreme Court. In documents filed with the court, Ms Pratt, the daughter of late packaging magnate Richard Pratt, claims Mr Waislitz, a billionaire in his own right, falsified records at their jointly owned private vehicle known as Jamahjo, which was the trustee of their Halex Family Trust.
