To file a proof of claim in bankruptcy court, complete Official Form 410, attach copies of documents that prove the debtor owes you money, and deliver the package to the clerk of the bankruptcy court handling the case before the filing deadline. There is no fee. Most non-governmental creditors have 70 days from the petition date, and missing that window usually wipes out your right to collect from the estate.
Do You Actually Need to File
Whether filing is required depends on the chapter the debtor filed under and how your debt shows up in the debtor’s paperwork.
In Chapter 7 cases, the trustee first determines whether there are any assets to distribute. If the initial notice tells you the case has no distributable assets, hold off. Should the trustee later find assets, the clerk mails a new notice giving you at least 90 days to file.1Cornell Law School. Federal Rules of Bankruptcy Procedure Rule 3002 – Filing Proof of Claim or Interest If the case is an asset case from the outset, you need to file to get in line.
In Chapter 12 and Chapter 13 cases, every creditor must file for the claim to be allowed.1Cornell Law School. Federal Rules of Bankruptcy Procedure Rule 3002 – Filing Proof of Claim or Interest The debtor is proposing a repayment plan, and creditors not on record aren’t paid.
Chapter 11 works differently. The debtor files schedules listing known debts. If your claim appears on those schedules as undisputed, fixed in amount, and liquidated, the schedules serve as your proof of claim and you don’t have to file separately. If your debt is listed as disputed, contingent, or unliquidated, is missing, or shows the wrong amount, you must file. When in doubt, file. There is no penalty for filing a valid claim that turns out to have been unnecessary.
The Deadline
The filing deadline is called the bar date, and it is among the most unforgiving deadlines in bankruptcy practice. The court does not remind you.
For Chapter 7, 12, and 13 cases, non-governmental creditors have 70 days after the bankruptcy petition is filed.1Cornell Law School. Federal Rules of Bankruptcy Procedure Rule 3002 – Filing Proof of Claim or Interest The clock runs from the petition date, not the date the notice reaches you. A slow-arriving notice eats into your window.
For Chapter 11 cases, the bankruptcy court sets the bar date by order, and it varies. The exact date appears on the notice the court sends you. These deadlines are usually longer than 70 days, but check the notice rather than assuming.
Government creditors get 180 days after the order for relief in Chapter 7, 12, and 13 cases.1Cornell Law School. Federal Rules of Bankruptcy Procedure Rule 3002 – Filing Proof of Claim or Interest The court can extend that on motion for cause.
The bar date appears on the Notice of Bankruptcy Case mailed to all known creditors. That notice also contains the case number, the debtor’s name, and the filing address. Keep it. You will reference it throughout the process.
Filling Out Official Form 410
Every proof of claim uses Official Form 410, which you can download from the U.S. Courts website.2United States Courts. Proof of Claim The form walks through numbered fields, and mistakes invite objections or delay.
Start with the basics from your bankruptcy notice: the debtor’s full name and the case number. Then enter your own name and the address where you want future court notices sent. If you have moved since the debt originated, use your current address, because objection notices and distribution checks will go there.
The form asks for the total amount owed as of the petition date, not the current balance.3United States Courts. Official Form 410 Proof of Claim Include principal, accrued interest, late fees, and other charges accumulated by that date. If you are unsure of the exact figure, estimate it and note on the form that the amount is approximate. An estimated claim is far better than no claim.
You will identify the basis for the debt (goods sold, services rendered, a loan, a lease, or whatever created the obligation) and classify it into one of three categories:
- Secured, meaning the debt is backed by collateral such as a mortgage, car loan, or financed equipment. You describe the collateral and state its value.
- Priority unsecured, meaning the debt gets paid before ordinary creditors. Common examples are unpaid wages (up to $17,150 per employee), child support, alimony, and certain tax debts.4Office of the Law Revision Counsel. 11 US Code 507 – Priorities
- General unsecured, which covers everything else: credit card debt, medical bills, trade payables, personal loans without collateral. These claims are paid last and often receive pennies on the dollar, if anything.
Classification matters because it decides where you sit in the payment order. Claiming priority you are not entitled to invites an objection from the trustee.
The form is signed under penalty of perjury. Filing a knowingly false claim is a federal crime carrying up to five years in prison.5Office of the Law Revision Counsel. 18 US Code 152 – Concealment of Assets; False Oaths and Claims; Bribery
What to Attach
Attach copies, not originals, of documents showing why the debtor owes you money and how much. Contracts, invoices, account statements, promissory notes, and correspondence acknowledging the debt all work. Stronger documentation means fewer challenges.
For a secured claim, you also have to include evidence that your security interest has been properly perfected.6Legal Information Institute. Federal Rules of Bankruptcy Procedure Rule 3001 – Proof of Claim Depending on the collateral, this could be a copy of a recorded lien, a certificate of title showing your interest, or a statement that the collateral has been in your possession since a specific date. Without perfection evidence, the trustee may treat your claim as unsecured, which usually means a much smaller recovery.
Before submitting, redact sensitive information. Show only the last four digits of Social Security numbers and financial account numbers, and use only the birth year (not the full date) for anyone named.7Legal Information Institute. Federal Rules of Bankruptcy Procedure Rule 9037 – Protecting Privacy for Filings Bankruptcy filings are public records, and the court will not catch redaction failures. That responsibility falls entirely on the filer.
Where and How to Submit It
You have several ways to get the completed Form 410 and attachments to the court.
By mail. Send the package to the bankruptcy court clerk’s office. The correct mailing address is on your Notice of Bankruptcy Case. If you want a file-stamped copy back as confirmation, include a duplicate of the form and a self-addressed, stamped envelope.8United States Courts. Official Form B410 Instructions
In person. You can deliver everything directly to the clerk’s office during business hours.
Electronically through ePOC. Many bankruptcy courts offer an Electronic Proof of Claim system on their websites. This is the easiest route for individual creditors because it does not require a CM/ECF login. The system walks through the form fields, accepts uploaded attachments, and files the claim directly. Look on the court’s website for a link labeled something like “File a Proof of Claim” or “ePOC.”
Through CM/ECF. The Case Management/Electronic Case Files system is the courts’ main electronic filing platform, but it is mostly used by attorneys and trustees.9United States Courts. Electronic Filing (CM/ECF) Some courts do allow individual creditors to use it. Check locally.
Through a claims agent. In large cases, especially big Chapter 11 filings, the court sometimes appoints a third-party claims agent to handle the volume. If your notice directs you to send the claim to an address other than the court itself, follow those instructions. The agent files with the court on your behalf.
Confirming the Filing Went Through
The clerk does not automatically confirm receipt. First-time filers get caught by this. There are two ways to verify. If you mailed the claim, request a file-stamped copy back by including a duplicate form and a stamped return envelope. Either way, you can check the court’s electronic records through PACER at pacer.uscourts.gov.8United States Courts. Official Form B410 Instructions PACER charges $0.10 per page, capped at the equivalent of 30 pages per document.10United States Courts. Electronic Public Access Fee Schedule
What Happens After You File
Once filed, your claim is presumed valid. Under federal law, a properly filed claim is deemed allowed unless someone objects.11Office of the Law Revision Counsel. 11 US Code 502 – Allowance of Claims or Interests The burden sits on whoever disagrees.
The trustee, the debtor, and other creditors all have the right to object.12Legal Information Institute. Federal Rules of Bankruptcy Procedure Rule 3007 – Objecting to a Claim Common objections dispute the amount owed, challenge priority status, or argue the debt is unenforceable. If an objection lands, the court sends formal notice and schedules a hearing. You respond with additional evidence, and the court decides what amount (if any) to allow. This is where thorough documentation earns its keep.
If no one objects, your claim stays on the record at the amount you listed, and you receive a distribution when the trustee pays creditors, assuming there are funds available at your priority level.
Fixing or Withdrawing a Claim
If you realize after filing that your claim contains an error (wrong amount, missing documents, incorrect classification), you can amend it by filing a new Form 410 with the corrections. Reference the original claim number on the amendment and mark it as an amended filing. Courts with ePOC generally let you amend electronically the same way you filed.
Withdrawing is also possible, but it gets more complicated once other parties have engaged with the claim. You can withdraw freely by filing a notice of withdrawal, unless an objection has already been filed, a lawsuit has been filed against you as part of the bankruptcy case, or you have already voted to accept or reject the debtor’s reorganization plan.13Legal Information Institute. Federal Rules of Bankruptcy Procedure Rule 3006 – Withdrawing a Proof of Claim; Effect on a Plan In any of those situations, you need the court’s permission, and the court can attach conditions. Withdrawing a claim also withdraws any vote you cast on a plan, which matters in Chapter 11.
Missing the Deadline
Consequences depend on the chapter.
In Chapter 7, 12, and 13 cases, the bar date is essentially absolute for ordinary creditors. Courts have consistently held that they have no discretion to extend it based on excusable neglect. Miss the 70-day window and your claim is disallowed. You receive nothing from the estate, even if the debtor plainly owes you the money.11Office of the Law Revision Counsel. 11 US Code 502 – Allowance of Claims or Interests
Chapter 11 is slightly more forgiving. A court can consider a late-filed claim if the creditor shows excusable neglect. Courts weigh whether allowing it would prejudice the debtor, how long the delay was, the reason for the delay, and whether the creditor acted in good faith. The reason for the delay usually carries the most weight, and courts focus on whether it was within the creditor’s control. Disorganization rarely qualifies. A notice genuinely lost in the mail has a better shot.
The safe posture is to treat every bar date as a hard deadline. Filing early with an estimated amount costs nothing. Filing one day late can cost the entire claim.
Penalties for a False Claim
Because Form 410 is signed under penalty of perjury, filing a knowingly false or inflated claim carries real exposure. Presenting a fraudulent claim against a bankruptcy estate is a federal offense punishable by up to five years in prison, a fine, or both.5Office of the Law Revision Counsel. 18 US Code 152 – Concealment of Assets; False Oaths and Claims; Bribery
On the civil side, the bankruptcy court can sanction anyone who files a document that is not well-grounded in fact or is submitted for an improper purpose, including an order to pay the other side’s reasonable expenses and attorney’s fees.14Legal Information Institute. Federal Rules of Bankruptcy Procedure Rule 9011 – Signing Documents; Representations to the Court These penalties target intentional fraud and bad-faith filings. Honest mistakes on the form will not land you in trouble, especially if you fix them promptly through an amended claim.
