What rights do we have as renters?

The most likely situation is that your verbal lease is a month-to-month agreement. It depends on why they're evicting you, but there are certain and specific notice procedures that they must follow before they're able to evict you. Usually situations like this work themselves out without having to proceed through an actual eviction process, but given the circumstances if they proceed by filing an eviction you should consult with an attorney about your options.
