Make a ticket unable to close if a field is not populated.

Make a ticket unable to close if a field is not populated.

Currently we have a system in place that automatically E-mails our ticketing system to create a ticket when we have failures. When this ticket is created we have an empty failure field. 

Our developers will pick up these tickets to fix the issue. 

Currently, our problem is that our developers will not always fill in the Failure Type field when closing the ticket.

Is there a way to make the ticket unable to close without this field being populated once picked up?

Many Thanks
