Anthony Koletti has pleaded not guilty to assaulting a 73-year-old woman at a park overlooking Sydney's eastern beaches.
The 43-year-old hairdresser previously represented himself in the matter.
But on Monday, he entered Downing Centre Local Court alongside solicitor Zali Burrows.
Among her breadth of clients, Burrows has represented disgraced former political staffer Bruce Lehrmann, one-time federal Labor leader and prime ministerial hopeful Mark Latham and a Sydney deputy mayor who boasted a lavish lifestyle and also had sights on The Lodge, Salim Mehajer.
Koletti's matter was set down for a two-day hearing starting June 11.
He is accused of assaulting the woman on July 23 at the Lighthouse Reserve in Vaucluse in Sydney's east.
She did not require medical treatment.
The park is a short distance from the Dover Heights home Koletti and Caddick shared before she disappeared in 2020.
Caddick, a self-styled financial adviser, went missing after plundering $23 million from family and friends via an investment scam to live a life of luxury.
The 49-year-old's luxury home had been raided days earlier by ASIC agents investigating her Ponzi scheme.
Coroner Elizabeth Ryan in May 2023 ruled Caddick was dead, but she was unable to determine the cause because most of her body had not been found.
The fraudster's badly decomposed right foot, which was still attached to a running shoe, washed up on a beach on the south coast of NSW in February 2021.
Investors defrauded by Caddick before her disappearance and death will recoup a portion of their $23 million in losses, after settling a class action lawsuit with her auditors earlier this year.
Koletti is not alleged to have any involvement in Caddick's fraud or her disappearance.
