Is what Bankruptcy, will it stop foreclosures proceedings, and what chapter?

Yes, if you file bankruptcy, it will stay a foreclosure sale.

Yes bankruptcy will stop foreclosure, for a while. It will stop the sale on the courthouse steps, but you should never file bankruptcy for this purpose alone. You must be in fact bankrupt, your expenses must exceed your income, and the chapter depends upon what is known as a "means test."

I am very confused by your questions. I think you are asking about filing for bankruptcy and what it can do for you. Please understand that filing for bankruptcy is a very complicated process. It is wise to talk to an experienced bankruptcy attorney before deciding to take this important step. Most Arizona bankruptcy attorneys offer a free consultation about the basics of bankruptcy. I am attaching a link to some free videos that explain how bankruptcy works. http://www.dianedrain.com/Bankruptcy/BankruptcyQuestionnaires/BKQuestionnaireInd.htm. There is no cost for the initial discussion. Please take time to educate yourself about bankruptcy and to determine which attorney is the best to assist you in the process. Don't assume the attorney is being completely honest about their experience and capabilities. Check them out. Avoid the attorneys who advertise on TV or profess a 100% success rate in their Internet ads. It costs hundreds or thousands of dollars for these ads and someone has to pay for them - the clients. These attorneys mass produce the work and do not offer the client the hands on assistance that is necessary in a well-planned bankruptcy. Normally these firms assign all or most of the work to paralegals and the client rarely talks to an attorney. When interviewing the attorney ask them how long they have practiced bankruptcy law. Ask what percentage of their practice is focused on consumer work. Ask whether they are experienced in both chapter 7 and chapter 13 cases. Ask the attorney for references. Ask about their policy of returning phone calls. They should be committed to answering specific questions about your situation and help you understand your options. If, after talking with them you are still confused about the issues you raised, find another attorney. Check them out with the various ranking sources: such as www.AVVO.com, and the State Bar. An attorney is should be your guide through this process. They should educate you, be there to assist you in how to avoid pitfalls and help you plan for your future after bankruptcy. There are hundreds of "bankruptcy" attorneys in Arizona. Of those just a few will fit the criteria set forth above. Again, bankruptcy is a very complicated process and you want to use an attorney who will be there when you need them. My best to you.
