To begin with, you can go to the [Judicial Authority of Ukraine] website (https://court.gov.ua/) there, go to the tab "Status of case proceedings" and look at the name of the employer to view all cases that are being considered or have already been considered in court regarding him

You also have the opportunity to check if the employer is not in the Unified Register of Debtors.
