Proof of Claim: What to File, When to File It, and What Happens If You Miss the Bar Date
You have a valid claim in a bankruptcy case. But filing a proof of claim is not optional if you want to get paid. The court does not automatically know you are owed money. You must tell it. The form is straightforward, but the timeline is rigid. Miss the bar date—the deadline to file—and you lose your right to recover, period. No exceptions. No waiver. This guide walks through the entire process.
What a Proof of Claim Is
A proof of claim is your formal notice to the bankruptcy court and the debtor that you are a creditor owed money. It establishes three critical facts: the amount you are owed, the basis of your claim (contract, invoice, judgment, whatever), and your right to participate in the distribution of the bankruptcy estate.
Without a filed proof of claim, the trustee or debtor assumes you either do not exist or have no interest in recovery. They will not look for you. They will not include you in distributions. You remain unpaid.
Official Form 410 Requirements
The bankruptcy court uses Official Form 410—"Proof of Claim." This is a standardized federal form. You can get it free from:
- The court's official website (under the specific case number)
- The case's claim agent website (e.g., Stretto, Prime Clerk)
- Courts.gov directly
Do not use an old version or a modified form. Use the current official form. Courts reject non-compliant forms.
What to Include on Form 410
The form has three sections:
- Creditor Information: Your name, address, phone, email. If you are a business, use your legal entity name.
- Debtor Information: The exact legal name of the bankrupt company, the case number, and the court jurisdiction. One small error here kills your claim.
- Claim Details: The amount owed (in dollars and cents), the date the debt arose, and—critically—the basis of the claim. "Goods sold" or "Unpaid invoice dated January 15, 2025" or "Personal services rendered" are acceptable. Vague claims like "money owed" are rejected.
Supporting Documentation
Attach copies (not originals) of:
- Invoices or payment requests
- Contracts showing the terms of payment
- Correspondence confirming the debt
- Court judgments (if you have won a lawsuit)
- Loan documents or promissory notes
The court will not go searching for evidence. If you do not provide documentation, the trustee will assume your claim is unsupported and may challenge or reduce it.
Bar Dates Are Jurisdictional
A bar date is the absolute deadline to file a proof of claim. It is set by court order early in the case. Miss it, and you lose your claim—permanently. No exceptions for ignorance, no waiver, no second chance.
Bar dates are almost never extended. Courts move them only in extraordinary circumstances (a discovery that thousands of creditors were not noticed, for example). If your bar date is April 1, 2026, at 5:00 PM Eastern, you must file by then. April 2 at 9:00 AM is too late.
How to Find Your Bar Date
- Check the case docket on PACER ($.10 per page)
- Visit the official case website (maintained by the claim agent)
- Check bankruptcy court notices mailed to your address
- Email the claim agent directly—they will tell you the deadline
Different claim categories sometimes have different bar dates. Secured claims, wage claims, and general unsecured claims may have staggered deadlines. Know which category you fall into.
PACER: How to Research Your Case
PACER is the Public Access to Court Electronic Records system. It is the official database of all federal court filings. To find your bankruptcy case:
- Go to pacer.uscourts.gov
- Create a free account (you can view documents; reading is free up to $15/month)
- Search for the debtor's name and the court jurisdiction
- Download the docket (case timeline) to find the bar date notice
Each document download costs $.10. A typical case docket runs $2–5 total. This is the authoritative source for your deadlines.
Priority Claims vs. General Unsecured
Not all claims are equal. Priority determines how much you recover.
Priority Claims (Paid First)
- Wages: Unpaid wages for work performed within 180 days of filing, capped at $15,150 per employee. If you are owed $25,000 in wages, you recover up to $15,150 as a priority claim and the rest as general unsecured.
- Recent Rent: Unpaid rent for the debtor's place of business or residence (lease only, not mortgage)
- Customer Deposits: Money you paid upfront (gift cards, deposits for services) gets limited priority under certain conditions
General Unsecured Claims
Everything else—vendors, suppliers, contractors, loan creditors. These get paid last, after secured creditors, administrative expenses, and priority claims. In many Chapter 11s, general unsecured creditors recover 0–5 cents on the dollar.
Specify your claim type clearly on Form 410. If you claim priority but do not qualify, the trustee will reclassify it as general unsecured and you lose the advantage.
Filing Methods
Electronic Filing (Preferred)
Most large cases offer online filing through the claim agent's website. You upload Form 410 and attachments. The system confirms receipt immediately. Filing closes at 5:00 PM Eastern on the bar date (check your specific case).
Mail Filing
Send Form 410 and attachments to the address listed on the bar date notice. Mail must be postmarked by the bar date. Receipt date does not matter; postmark date does. Send via certified mail with return receipt so you have proof.
Hand Delivery
Some courts accept hand delivery to the clerk's office during business hours. Verify the address and hours before the bar date. Bring the original plus two copies.
After You File: What Happens Next
The trustee or debtor reviews your claim. They may:
- Allow it: Accept your claim as filed. You are on the claims register.
- Challenge it: File an objection in court. You will have a hearing to defend your claim.
- Reduce it: Allow part but dispute the rest. Common for duplicate claims or claims that exceed documented amounts.
If your claim is challenged, you have the right to respond in writing or at a hearing. This is where supporting documentation matters. A vendor without invoices loses to a vendor with invoices.
Common Mistakes to Avoid
Wrong Case Number
A company may have multiple bankruptcy cases (separate entities). If you file in the wrong case, your claim is worthless. Verify the exact case number three times before filing.
Wrong Debtor Entity Name
If you dealt with "Acme Corp, LLC" but file against "Acme Holdings, Inc.," your claim will be rejected or challenged. Use the legal name exactly as it appears on the bankruptcy petition.
Unsigned or Incomplete Form
Form 410 requires your signature (or electronic equivalent if filing online). Unsigned claims are rejected. Fill in every required field. Blank spaces signal incomplete submission.
No Supporting Documentation
Filing the form alone, without invoices or contracts, leaves your claim vulnerable to objection. The burden is on you to prove the debt, not on the trustee to believe you.
Filing After the Bar Date
This is the mistake from which there is no recovery. Once the bar date passes, you cannot file. Your claim is barred forever, even if the court later finds you were entitled to it.
Key Takeaway
A proof of claim is your legal right to recover money in bankruptcy. File it on time, use the official form, include documentation, and specify your claim type. Miss the bar date and you lose everything. When in doubt, file early—there is no penalty for early filing, and the deadline is absolute.
