The matter will be taken to court next year.
Guy Sebastian and his former management have filed lawsuits against each other following allegations the singer is still owed money from a number of services.
As reported by Fairfax, Sebastian alleges he is still owed by 6 Degrees Management for a number of brand endorsements, The X Factor performances and supporting a Taylor Swift tour.
According to court documents, the inaugural Australian Idol winner claims that one of the endorsements, with sunscreen brand Solar D in 2016, was only put in place to keep him as a client of 6 Degrees and that he is still yet to be paid for it.
Sebastian's former manager Titus Day and 6 Degrees have denied the allegations and are counter-suing the artist.
Sebastian has alleged he is still owed over $200,000 in live performance fees.
The matter will be taken to court on 14 February.
