Do you still have a key to get into the property?
Are they up to date with rent?
Why do you want them out?
If they are not up-to-date with rent by two weeks, or they have overstayed their notice, you can simply lock them out which is why I asked the question. I don't know why you are bothering with an application to court if this is a commercial property.
There is no need to use any form at all.
