A defence lawyer for a Launceston pair accused of human trafficking and slavery told a court the circumstances of the case were distressing for her clients.
The AFP has so far alleged a woman was deceived into coming to Australia and enslaved between October 5, 2018, and February 24, 2019.
The 52-year-old man and 43-year-old woman, who cannot be named for legal reasons, are yet to enter pleas to possessing a slave and trafficking in persons.
A joint operation between the AFP and Tasmania Police led to the arrest of the pair in July.
Appearing in the Launceston Magistrates Court on Tuesday, defence lawyer Roona Nida initially opposed a prosecution submission to have proceedings adjourned until December 10 because her clients weren't eligible for Legal Aid, therefore it was costing them time and money.
"The prosecution has had plenty of time to investigate this matter," Ms Nida said.

But Commonwealth prosecutor Rose Bollard told the court the delay was beneficial to defence, with the Crown likely to amend the charges' particulars after further evidence, including additional witness statements, telephone intercepts and surveillance, was compiled.
Ms Nida said she wasn't fully aware of the prosecution's intention to amend the charges and it was in her client's best interest to have another mention under the circumstances.
A heated exchange ensued between Ms Nida and Magistrate Ken Stanton after the defence lawyer said she believed the prosecution was buying time to make a weak case stronger and asked Mr Stanton to give them a direction about the investigation.
Mr Stanton dismissed the submission.
The pair were bailed to reappear on December 6.
