It sounds like you have gotten pretty far without hiring an attorney - but that distance might have ended. I would highly recommend you speak with an experienced California Chapter 13 bankruptcy attorney. While you might get the information you are looking for here, nothing replaces the real time human involvement of a consumer bankruptcy attorney.
I am an attorney licensed to practice law in Ohio and some Federal Courts throughout the United States. I am not answering your question to solicit you as a client and there is a good chance that I am not licensed to practice law in the state that you reside. I hope that you find my assistance beneficial and, at most, use my advise as a finger pointing in the right direction. An attorney client relationship is not established by posting back and forth online. One of the most beneficial aspects of working with an attorney is the attorney client privilege which does not exist when you post personal facts online to faceless strangers. Hire an attorney if you want specific legal advise. If you cannot afford one, call your local bar association or search "(your city) legal aid" online. The fact that you took the time to post your question online likely means that you could use the aid of an attorney. Call around your area and see if any local attorneys offer free consultations.
Assuming the automatic stay is still in effect in your case (you are not a serial filer and the case has not been dismissed), file and serve the Notice of Stay you have referenced. You do not need to file an answer. I don't believe you even have to pay a first paper filing fee, although I am uncertain about that. Be sure to attach a copy of the order from the BK court to your notice. Remember you cannot serve the Notice on opposing party, you need have a non-party adult prepare and sign the proof of service.
I am licensed in California only and my answers on Avvo assume California law. Answers provided by me are for general information only. They are not legal advice or counsel. Answers must not be relied upon. Legal advice and counsel must be based on the interplay between specific exact facts and the law. This forum does not allow for the discussion of that interplay. My answer to any specific question would likely be different if that interplay were explored during an attorney-client relationship. I provide legal advice and counsel during the course of an attorney-client relationship only. The exchange of information through this forum does not establish such a relationship. That relationship is established only by personal and direct consultation with me followed by the execution of a written attorney-client agreement signed by each of us. The communications on this website are not privileged or confidential and I assume no duty to anyone by my participation on Avvo or because I have answered or commented on a question. All legal proceedings involve deadlines and time limiting statutes. So that legal rights are not lost for failure to timely take appropriate action and because I do not provide legal advice or counsel in answer to any question, if you are an interested party you should promptly and personally consult with an attorney for advice and counsel. Also, see Avvo's terms and conditions of use, specifically item 9, incorporated by this reference
Mr Daymude is correct. A first paper fee is not required; and assuming the landlord was scheduled and received notice of your BK, you do not need to serve the CM-180 ... the creditor has an affirmative duty to terminate the proceeding (and, in fact, refile the UD Complaint after relief from stay has been obtained).
