The easiest option is to simply file a quitclaim deed with the county register of deeds. After filing the deed, mail a copy, by certified mail, to the mortgage creditor. There must be "delivery" and "acceptance" for a valid transfer. Under Kansas law, unless the mortgage company rejects the deed, they are deemed to have accepted it. This option can be used by anyone, whether or not a bankruptcy is filed.
Another option, available only to homeowners who file a chapter 13 bankruptcy, is to simply include language in the chapter 13 plan stating that title to the property vests in the mortgage company upon confirmation of the plan. Section 1322(b)(9) gives bankruptcy courts the power to vest property of the estate in any entity upon confirmation of the plan.
The other option is to file a motion with the Court for a sale under section 363 of the bankruptcy code. Debtors in a chapter 13 are given the trustee's section-363 power to sell by section 1303 of the Code. This method is much more time consuming than a quitclaim deed, but has the added security of a court order confirming the sale and title insurance as part of the sale.
