How to File Your Chapter 13 Proof of Claim

A Chapter 13 proof of claim tells the court and the debtor exactly how much you say you are owed, and why, so you get paid through the repayment plan. Filing one is your formal request to participate in the money the debtor pays out over three to five years.

Think of it as your invoice to the bankruptcy system. Without it, your debt is essentially invisible to the plan. For example, if you are a credit card company owed $5,000, your proof of claim locks in that $5,000 figure and attaches the cardholder agreement. A mortgage lender would file one to state the exact arrears, interest rate, and missed payment dates so those get cured in the plan. If you do not file, the trustee has no obligation to route payments to you, even if the debtor listed you in their initial paperwork.

You typically do not need to file a proof of claim in your own Chapter 13 case because your attorney already listed your creditors when they filed your petition and schedules. That official list acts as an informal proof of claim for creditors you want to pay through your plan, such as a mortgage, car loan, or back tax obligation.

The real question is whether you need to file on behalf of a creditor who missed the deadline or failed to file for themselves, which sometimes happens when a smaller creditor overlooks the bankruptcy notice. If a creditor you must repay (like a priority tax claim) does not file their own proof of claim, your plan could face confirmation problems or that debt might not get paid correctly, so you step in to protect your plan.

Most Chapter 13 filers only file a proof of claim when a secured or priority creditor fails to do so and leaving them out would jeopardize the repayment structure or discharge. Check your creditor mailing matrix first, confirm whether the missing creditor is one you genuinely must pay through the plan, and only then prepare to file a proof of claim on their behalf before the bar date passes.

Before you touch the proof of claim form, pull the exact numbers, dates, and account identifiers directly from your records. The court needs a specific, sworn statement of what the debtor owes you, not a round estimate. You will typically need the total amount owed as of the Chapter 13 filing date, the original account number, and the date the debt was incurred. If a portion of your claim is for interest, fees, or other charges, separate those amounts now so the form can be completed accurately later.

The single most important detail is the date the bankruptcy was filed. Every dollar figure on your proof of claim, including any interest or ongoing charges, must be calculated up to that precise moment. Pulling this information together before you start filling out the form prevents arithmetic mistakes and mismatched numbers that are the most common reason claims get challenged or temporarily rejected.

Filling out the official proof of claim form (Form B410) becomes straightforward once you have your claim details from the previous step. The form acts as your invoice to the bankruptcy court, so accuracy here directly determines whether you get paid. Take it one numbered box at a time.

1. Box 1: Debtor's Name - Enter the full name exactly as it appears on the bankruptcy notice you received. If it's a joint case, include both names just as the court lists them.
2. Box 2: Case Number - Copy the number from the top of the official notice. Double-check every digit; a wrong number misfiles your claim.
3. Box 3: Your Info - Put your name, mailing address, and phone number. If an attorney files for you, use the attorney's contact details and check the box indicating they are filing on your behalf.
4. Box 4: Account Number - Use the last four digits only, unless the full number is essential to identify the debt. This protects the debtor's privacy on the public record.
5. Box 5: Claim Amount - As you gathered earlier, state the precise amount owed on the petition filing date.
6. Box 6: Basis for Claim - Check the appropriate box. For most creditors, this is 'Goods and services' or 'Money loaned.' If there is a written contract, attach a copy.
7. Box 7: Secured Claim - If collateral backs your claim, check 'Yes' and describe the property. List its current value and the amount owed that the collateral covers. If unsecured, simply check 'No.'
8. Box 8: Priority Claim - Check this only if you are owed domestic support or certain tax debts under Chapter 13 priority rules. Refer to the form's instructions if you are unsure, as priority status changes your payment position.
9. Box 9: Signature - Sign and date the form. An electronic signature is acceptable in most courts, but a wet signature is required if mailing paper copies.

Any attachments you flagged in Box 6 or Box 7 belong after the signature page, which you will prepare in the next step.

The dollar figure on line 6 must match the exact amount the creditor's records show you owe on the petition date, not an estimate or a balance from an old statement. If you list too high a number, you risk the court disallowing your claim entirely; too low, and you leave money on the table that the Chapter 13 plan could have paid you.

Double-check the date of the debt and the original account number, not a transferred or internal reference number. These details are how the bankruptcy court and the trustee cross-reference your claim against the debtor's schedules and creditor mailing matrix. A mismatch in the account number is one of the most common reasons a proof of claim gets flagged or rejected, even if the amount is right. Pull these directly from a recent billing statement or the creditor's own system of record immediately before you fill out the form.

Most claims don't require backup, but if the debtor or trustee could reasonably question the amount, age, or validity of the debt, attaching the right supporting documents prevents your proof of claim from being reduced or disallowed. A quick rule to follow: attach proof for any debt that isn't a simple, recent credit card or medical bill already listed correctly by the debtor. Common examples include judgments, security interests, old accounts, or assignments from another creditor.

Keep the attachments focused. A few clear pages work better than a stack of statements. What to include:

• A copy of the signed contract, promissory note, or account agreement
• The most recent account statement showing the balance before filing
• A recorded judgment or lien document for secured claims
• An itemized payment history if fees or interest are still accruing
• A clear assignment or bill of sale if you bought the debt
• A short cover sheet labeling each exhibit (Exhibit A, B, etc.) referenced on the form

Always redact full account numbers that aren't already listed on the form, and never attach original documents, only copies. If you're unsure whether backup is needed, including a concise set of exhibits is safer than offering too little.

You must file your proof of claim before the court's bar date, a strict deadline typically set 70 days after the petition date for most creditors, though government entities usually get 180 days. Missing it almost always means the debt gets wiped out in the Chapter 13 plan without any payment.

Here is how to protect your claim:

• Pin down your exact deadline. Do not guess. Check the official 'Notice of Chapter 13 Bankruptcy Case' you received from the court. It lists the precise bar date for your case.
• Factor in mail and processing time. If you file by mail, send it early enough to arrive several days before the deadline. A postmark on the deadline day is not enough; the court clerk must receive it by the cut-off.
• Check for a changed deadline in rare cases. If the debtor adds you to the creditor list late or the court grants an extension, you may get a new notice with an updated date. Always use the most recent official notice.
• Verify local electronic filing rules. Many courts set a specific cutoff time, often 11:59 p.m. local time, for electronic submissions on the deadline day. If you use the court's e-filing system, confirm that your submission completes before that time.

A tardy claim is typically disallowed outright. If you miss the deadline for reasons beyond your control, you may need to file a motion with the court asking for permission to file late, but approval is never guaranteed and requires a strong legal reason.

You must file your proof of claim with the specific bankruptcy court handling the debtor's Chapter 13 case, never a general courthouse or another district. Sending your proof of claim to the wrong location is a common and costly mistake because a clerk cannot forward it for you, and you will likely miss the bar date before realizing the error.

The correct method depends on whether you are a creditor or the debtor filing on behalf of a creditor. Most courts now require or strongly prefer electronic filing through the court's Case Management/Electronic Case Files (CM/ECF) system, though paper filings are permitted in limited situations. Always verify the official procedure for the division where the case is pending.

Here is where to direct your filing:

• E-filing through CM/ECF: If you are an attorney or a registered creditor, file directly into the system using the case number. This gives you an instant timestamped confirmation.
• Mail to the Clerk's Office: If you are filing by paper, mail the original to the exact address of the Bankruptcy Court Clerk listed on the debtor's notice of the 341 meeting, not a U.S. District Court or another division.
• Verify the correct court: Use the case number prefix (e.g., 2:23-bk-12345) to confirm the specific district and division. A case filed in the Eastern District of California cannot be filed in the Central District.

Always confirm the current mailing address and e-filing rules on the court's official website before sending anything. A single wrong envelope can void your right to payment in the Chapter 13 plan.

After you file your proof of claim, the court clerk typically dockets it and the Chapter 13 trustee reviews it for payment. If your claim appears correct and no one objects, you will simply start receiving your share of the plan payments once the debtor's repayment plan is confirmed.

The trustee and the debtor's attorney will have a chance to object to your claim if something is missing or the amount seems wrong. If that happens, you will receive a notice explaining the issue, and you may need to attend a short hearing or amend your claim, which ties directly into correcting a rejected claim quickly.

If your claim is accurate and filed on time, the worst thing you can do now is forget about it. Keep your filed copy with the court's date stamp, and monitor the mail for any notices. You generally do not need to take further action unless the court or trustee contacts you.

If your proof of claim is rejected or marked incomplete, act immediately because the original filing deadline typically still controls your ability to correct it. The court clerk's notice will usually explain the specific problem, so fix only what they flagged and resubmit as a complete package right away.

Often the fix is straightforward once you spot the error:

• missing signature or date on page 2
• wrong debtor name or case number
• amount doesn't match the attached documentation
• no supporting documents when required, like a promissory note or payment history
• using an outdated form version that the court won't accept

Make the exact correction, attach a clean copy of the entire proof of claim with the update, and include a brief cover note referencing the rejection. If the deadline hasn't passed yet, you can simply file the corrected version. If the deadline has passed, file it anyway with a short explanation, some courts will accept a timely corrected claim that merely fixes a technical defect rather than asserting a brand new claim. Check your local rules, and when in doubt, call the clerk.
