Czech to English Law/Patents Finance (general) Bankruptcy

Hello there,
Hope someone can help with this... I am translating a text about a bankrupt bank and am stumped by "incidencni zaloba". The source text says:

Z celkového poctu 222 ***incidencních zalob***, jejichz pravomocné rozhodnutí je podmínkou ukoncení konkursu zkrachovalé banky, jich bylo ke konci brezna 111 pravomocne skonceno. Jak dnes nás informoval správce konkursní podstaty banky, v naprosté vetsine ukoncených sporu uspela. V ***incidencni zalobe*** soud rozhoduje, zda narok je opravneny.

I checked with the customer and they sent me the following

"Incidencni zaloba" is a special type of action (lawsuit) that can be brought by a trustee or creditors during the second stage of a bankruptcy proceeding, when the trustee is putting together the list of assets in bankruptcy. This kind of action is brought when there is a dispute about what exactly belongs on the list.
Simply said they are arguing at court who owes money to whom, how much money they owe, and who has a claim on certain assets.

The customer thinks it may be called an "incidence lawsuit" but I cannot many incidences of incidence lawsuit. I hope that someone will be able to point me in the right direction.
Thank you
