dig <domain> ns fails when local name servers misconfigured

Hi all,

We have been using dig to retrieve a domain's name servers for years.  
Unfortunately, the dig syntax we normally use does not work when name  
servers are misconfigured. Currently, dig is returning an empty name  
server list for domain ilap.ca:

     dig +short ilap.ca ns
         < empty list >

For testing purposes, we removed the zone statement for the domain.

We would like to take some action when domain authority transfers take  
place. Can we configure dig to return the name server list based  
exclusively on a query to the root / TLD servers? Can local name  
servers be ignored?

Thank you for any advice.
