if my house is in forecloserand 5 days til sell date can i still file chapter 13

Yes, you can file a chapter 13 bankruptcy and stop the sale date of your house.  You can pay your mortgage payments and the arrearage you owe through your chapter 13 plan to get you back on track.  You may also be able to file for a mortgage modification through your chapter 13 if your district allows this and if your loan has not already been modified.  This is a great tool to help you force the lender to deal with your modification paperwork.  They may be able to reduce your payments to 31% of your income and roll over your back payments into the modification to get you back on track.  A chapter 13 bankruptcy is a very detailed bankruptcy and I suggest that you speak to an attorney about your rights and possible representation before you file.  I hope you found this answer useful.
