Read the status field The status is the register's own verdict on whether the entity currently exists. Treat anything other than active/registered as a red flag before contracting.

Check the last filing date An entity can be nominally active but years behind on filings. A long gap since the last filing is a warning sign even when the status reads active.

Confirm at the source Status changes propagate from ARES at https://ares.gov.cz. For a decision with money attached, confirm there.
