When you void checks, they are no longer visible on the Checks screen. If you want to un-void these checks for some reason, follow these steps:

1. Go to the Checks screen and filter it for voided checks. For that, you need to select the filter Void and set it to Yes. This makes the voided checks visible. Check CORE Help Center for more on filtering the Checks screen.
2. Select the voided checks that you want to un-void and then click Actions > Un-Void.
3. On the Unvoid dialog, select the confirmation check box and click Submit.

The checks are now un-voided and visible in the list view.
