what is question 15 when filing chapt 13?

They way you state your question is very unclear.   11 USC 1325(a)(6) sets forth one of the requirements for confirmation of a Chapter 13 plan, and that is that the debtor has provided evidence to show that they will be able to make all the payments necessary under the plan. The Statement of Financial Affairs is part of the petition.  Question 15 on the Statement of Financial Affairs (which you had to sign under penalty of perjury to file your case) requires you to list all addresses and dates you lived at in the 3 years prior to filing your bankruptcy petition. Hope this answers your question(s).  If it doesn't (and even if it does) I highly advise that you consult with an experienced bankruptcy attorney in your area.   Based on a recent study on success rates of those not represented by a bankruptcy attorney conducted by the courts in the largest bankruptcy district in the country, less than 1% of Chapter 13 cases filed by debtors without an attorney survive to discharge.   Mark Markus has been practicing exclusively bankruptcy law in California since 1991.  He is a Certified Specialist in Bankruptcy Law by the State Bar of California Board of Legal Specialization,  AV-Rated by martindale.com, and A+ rated by the Better Business Bureau.
