Your bankruptcy wipes out your obligation on the debt. It does not touch your co-signer's. If your mother co-signed your car loan or your brother co-signed a credit card, the lender can still collect the full balance from them after your case is finished, and in a Chapter 7 nothing in your case stops it from starting.
That is the uncomfortable part of the answer, and many people do not hear it until after they have filed. Here is how it actually works.
Your discharge belongs to you, not to the debt
The Bankruptcy Code says this directly. Under 11 U.S.C. section 524(e), discharge of a debt of the debtor "does not affect the liability of any other entity on, or the property of any other entity for, such debt." The discharge is an injunction against collecting the debt as a personal liability of the debtor, which means you. It is not an eraser that makes the debt disappear.
So if you and your sister are both signed on a $9,000 credit card and you file Chapter 7, the card company loses its right to collect from you and keeps every right it ever had against her. Not half of it. All $9,000. Co-signers are usually jointly and severally liable, which is the legal way of saying each of them can be asked for the entire amount.
In a Chapter 7 there is no shield for the person who signed with you
The automatic stay that takes effect the moment you file protects you. It does not protect your co-signer. Sometimes a co-signer is left alone for a few months simply because the creditor is busy with your case, and then the letters and phone calls begin.
What this looks like from the trustee's chair
Brian is one of only four Chapter 7 Bankruptcy Trustees in the District of Nevada, so he reads petitions from the other side of the table as well as filing them.
From that chair, your co-signer is not the trustee's concern at all. A trustee administers the estate and looks for unprotected value that belongs to creditors. Who else signed the note is no part of that job. The pressure a co-signer feels comes from the creditor, a separate party with its own lawyers and its own collection department, which is exactly why your filing does not make it go away.
Chapter 13 can protect a co-signer, within limits
This is the piece worth knowing before choosing a chapter. Chapter 13 has something Chapter 7 does not, a co-debtor stay under 11 U.S.C. section 1301. After a Chapter 13 is filed, a creditor generally may not act or commence or continue a civil action to collect a consumer debt from an individual who is liable on that debt with the debtor or who secured it.
The limits are real. It reaches consumer debts, not debts the co-signer took on in the ordinary course of that person's own business. It ends if the case is closed, dismissed, or converted to Chapter 7. And the statute lets a creditor ask the court to lift it, including where the plan does not propose to pay that claim. Whether Chapter 13 is the right chapter depends on income, debts, and what someone is trying to protect, and for many people it is not. But if shielding a co-signer matters, it belongs in that conversation.
Continuing to pay is a separate question
Plenty of people want to keep paying the car a parent co-signed precisely so the parent is never contacted. Whether that works depends on the equity in the collateral, whether Nevada's exemptions cover it, whether the lender keeps accepting payments after a filing, and what the loan documents say about bankruptcy. It varies, and anyone who answers without looking at the loan and the numbers is guessing.
Put every co-signer on the table at the first conversation
Co-signers are one of the most common things left out of an intake, usually because the arrangement was informal or because a family member does not feel like a creditor. It needs to come up at the start, while the choice of chapter is still open and there is still time to warn the person.
Talk it through before you file
If someone co-signed for you, that is a reason to get advice early, not a reason to put off filing. Consultations with the Law Office of Brian D. Shapiro are free and are held by phone or video call, so there is nowhere to drive. Chapter 7 cases can be started with $0 down in attorney fees, with no attorney fees until after the petition is filed, though the court's filing fee is paid before filing.
