The star has filed a suit with the Supreme Court of Victoria against the famous Producer Pete Waterman and his company PAL Productions.
The singer is claiming not to have touched any of the royalties that she had a right to with the sales of her album Greatest Hits, which came out in 1992, and was released again in 2002.
According to her lawyers, the pop star has money owed to her in the amount of $830 000 US.
PAl has already paid Minogue $500 000, but may have accumulated interest, other damages and charges.
Waterman is the producer responsible for her success with I Should Be So Lucky.
