Do I have to pay Condo fee during the period in between foreclosure sale, and Bankruptcy discharge?

I got Chapter-7 Bankruptcy discharge; moved out of the property and rented another apartment, key was replaced, Substitute trustee was assigned, and I had no access at all to the Condo. It took more than a year for foreclosure sale. The Condo management sued me to pay all fee for more than a year claiming that unless the condo is sold, i remain the owner even though i have no access and control.
