If you're being evicted and missed a court date or didn't answer legal papers you received, the landlord will get a default judgment. This document allows the landlord to evict you under court order, and a City Marshal's Notice will follow. Fortunately, there is something you can still do that may help to preserve your tenancy. Go here at the Law Help Interactive site.
This is a free online program that will create an affidavit to support an Order to Show Cause. The affidavit is a legal document that gives your reasons for not appearing or answering. It asks the judge to halt eviction proceedings until you have an opportunity to appear and tell your side of the story. The judge, if convinced your explanation might justify it, can then sign an Order to Show Cause, which will give you a chance to return to court and raise your defenses.
However, it does not give legal advice and you should be aware that no program of this sort can ever substitute for the assistance an experienced Tenants' lawyer can supply. As a non-attorney, when you try to be your own lawyer, you're at risk. If your funds are limited, it's to your advantage to at least try to have an initial consultation with qualified legal counsel, to get some overall advice about your case, and to help you avoid mistakes that can be fatal to your tenancy.
