Proof of Claim

A Proof of Claim is a bankruptcy filing through which a creditor or other authorized party formally asserts a claim against the debtor's estate, stating the amount, basis, priority or secured status and supporting information required by applicable bankruptcy law and rules.

Filing puts the creditor's asserted claim into the case

Section 501 provides the basic statutory authority to file.

The proof typically identifies the creditor, debtor, claim amount, basis and whether the claim is secured, unsecured or entitled to a claimed priority. The bankruptcy rules and court orders determine the form, filing method and deadline.

Scheduled claims can change the filing analysis in Chapter 11

A creditor whose Chapter 11 claim is properly scheduled as undisputed, noncontingent and liquidated can be treated differently from a creditor whose claim is omitted or listed as disputed, contingent or unliquidated.

That is why creditors compare the debtor's schedules with their own records rather than assuming the debtor's filing protects them.

The bar date can be economically decisive

A bar date is the deadline established by the applicable rules or court order for filing specified claims.

Missing it can jeopardize a creditor's right to receive distributions, although exceptions and late-claim rules can apply in particular circumstances. Deadline analysis should be based on the actual court order and claim type.

Supporting documentation matters

A claim can be challenged if the asserted amount, lien, priority or contractual basis is unsupported.

Invoices, loan documents, judgments, security agreements and account records can become important when another party disputes the filing.

Filing strategy should start with the debtor’s schedules and the bar-date order

Assume a creditor is owed $4 million under a loan agreement. The debtor schedules the claim at $4 million, undisputed, noncontingent and liquidated. That may create a different filing posture from a claim listed at $2.5 million and marked disputed.

The creditor should compare:

its own records → the debtor entity that owes the debt → the scheduled amount and status → the applicable bar-date order → whether a proof of claim is required.

In a multi-debtor case, asserting the right amount against the wrong entity can create a different problem from asserting the wrong amount against the correct entity.

The claims process is therefore both substantive and administrative. Good documentation preserves the economic claim; correct filing preserves the procedural route for that claim to be recognized.

Common mistakes

Treating a filed claim as automatically final It can still be objected to.

Assuming every scheduled creditor must always file Chapter 11 rules can treat properly scheduled claims differently.

Ignoring the debtor name Large Chapter 11 cases can involve many debtor entities, and the claim must be asserted against the correct obligor.

Example

A vendor is owed $250,000 before the bankruptcy filing. The debtor's schedules list the debt as disputed. The vendor files a proof of claim before the applicable bar date, identifies the debtor, states the $250,000 amount, describes the invoices and attaches supporting documentation.

Professional note

A proof of claim is not the same as an allowed claim. Filing puts the asserted claim into the bankruptcy claims process; allowance can still be challenged through objection, estimation, subordination or other statutory procedures.
