Typical cases . . .
So what do you do when you've rented an apartment to a Tenant and the Tenant has other people living there with them but you don't know if the Tenant is receiving money from them? In any event, however, you just want the other people out (and perhaps you wouldn't mind evicting the Tenant as well, but the priority is to get the other people out because you don't have a lease with them?
Should you sue the Tenant for illegally subletting?
