I cosigned for a loan for my nephew and im planning on filing bankruptcy. I heard about this co debtor stay that applies to spouses and just wondered if it could apply to me as an Aunt.
No. The co-debtor stay that you are referring to exists only in Chapter 13 bankruptcies, Not Chapter 7 cases. Under Section 1301 of the Bankruptcy Code, when a Debtor files Chapter 13, there is a co-debtor stay with respect to co-obligated CONSUMER debts. However, unless the Chapter 13 Plan specially provides for payment in full of that co-obligated debt, the creditor can seek an order from the bankruptcy court terminating the co-debtor stay.
You clearly state that your nephew is filing a CHAPTER 13. If he schedules this debt to be sub-classed and paid in full to protect you, the co-debtor, you will be protected under Section 1301. If he files under Chapter 7 there is no co-debtor protection. Check his Chapter 13 Plan (of which you should receive a copy from the Court as a co-debtor) to see how he is treating this obligation. By the way, the co-debtor stay applies to aunts, uncles, spouses, and even non-related parties. The co-debtor is protected in a Chapter 13 to the extent the Debtor is paying the debt.
