Craig Thomson's lawyers say they are yet to agree to the facts surrounding the former federal MP's alleged misuse of union credit cards.
Thomson is accused of misusing credit cards on items including female escorts and X-rated movies while he was national secretary of the Health Services Union (HSU) and a Labor MP.
During a brief hearing in the Melbourne Magistrates' Court on Tuesday, his lawyer Greg James QC asked prosecutors to provide a list of agreed facts.
Mr James has previously told the court there was likely to be "very little" factual dispute in the case, but there would be argument about Thomson's authority to use the cards.
Prosecutor Michelle Williams said there would be about 40 witnesses who would testify about the authority issue.
Magistrate Charles Rozencwajg ordered the statement of facts and list of witnesses be given to Thomson's lawyers by September 20.
Thomson, 49, is accused of misusing the HSU credit cards 49 times over a five-year period amounting to expenditure of $28,000, or $150 per week.
He allegedly purchased pornographic films, female escorts, firewood, flights and cigarettes for his wife and made cash withdrawals.
Thomson is facing 11 charges of theft, 31 charges of obtaining property by deception and 131 charges of obtaining a financial advantage by deception.
His seven-day hearing will begin in the Melbourne Magistrates' Court on December 2.
Thomson stood as an independent in Saturday's election, attempting to retain his NSW central coast seat of Dobell, but he was soundly beaten by Liberal Karen McNamara.
