Ask a landlord-tenant lawyer and get answers ASAP
Hello. My name is***** will be happy to answer your question.
I am sorry to hear about this unfortunate situation.
Unfortunately, the only way to legally remove the tenants whether there is a written lease or not is to pursue legal eviction through the local court and also lawsuit for any damages (unpaid rent / utilities) could be pursued through the local court.
Here is the link to the official ND Courts with the instructions related to filing and pursuing an eviction or you can hire a local attorney to help you evict the tenants and collect any damages:
I wish you the best of luck!
