Section 9 of the IBC: how operational creditors file for insolvency
Suppliers, service providers, contractors and employees — the IBC calls them operational creditors, and it gives them their own route to trigger a corporate insolvency when invoices go unpaid. But the Section 9 route has a strict pre-condition and one famous trap: the pre-existing dispute. Here's how the process actually works.
Who is an operational creditor?
An operational creditor is owed an operational debt — a claim arising from the provision of goods or services (including employment), or statutory dues owed to the government. This is distinct from a financial creditor, whose debt arises from money lent against consideration for the time value of money. The distinction decides which section you file under — financial creditors use Section 7; operational creditors must follow the two-step Section 8 + Section 9 route.
Step 1 — The Section 8 demand notice
Before anything reaches the NCLT, the operational creditor must deliver a demand notice to the corporate debtor:
- Form 3 — a demand notice for the unpaid operational debt; or
- Form 4 — a copy of the invoice with a notice to pay.
The debt must meet the ₹1 crore minimum default threshold. The notice is best delivered to the registered office (and by email to key managerial personnel) with proof of delivery preserved — service of the notice is routinely contested at admission.
Step 2 — The 10-day window
The corporate debtor then has 10 days to do one of two things:
- Pay the unpaid amount and point to the payment; or
- Raise a dispute — bring to the creditor's notice the existence of a dispute about the debt, or a pending suit or arbitration filed before the demand notice.
Step 3 — The Section 9 application
If the 10 days pass with no payment and no valid notice of dispute, the operational creditor files the application before the NCLT in Form 5, accompanied by the invoice or other proof of debt, an affidavit that no notice of dispute was received, and — where available — a confirmation from the creditor's bank that the amount remains unpaid. The applicant may also propose a Resolution Professional (it is optional for a Section 9 filing).
In Mobilox Innovations v. Kirusa Software (2018), the Supreme Court held that if a plausible, pre-existing dispute exists — one that is not "spurious, hypothetical or illusory" — the NCLT must reject the Section 9 application. The tribunal does not decide who would win the dispute; it only checks that a genuine dispute exists. This is the single most common reason operational-creditor applications fail. Before filing, audit your own correspondence: quality complaints, debit notes, contested reconciliations — anything the debtor raised before your demand notice can defeat the application.
Admission and what follows
If the application is complete, the debt is due, and no pre-existing dispute exists, the NCLT admits the application — CIRP commences, the moratorium takes effect, and an IRP takes charge of the company. From there the process is the same as any CIRP: claims, the Committee of Creditors, resolution plans or liquidation.
What operational creditors should know before filing
- Section 9 is a resolution trigger, not a recovery weapon. Tribunals dismiss applications filed purely as pressure tactics for disputed dues.
- Operational creditors generally do not sit on the CoC — though recent amendments give the largest OCs an observer seat. Your claim rides on the process others steer.
- In a resolution plan, operational creditors must receive at least their liquidation value — and be paid no later than financial creditors.
- Documentation wins cases: clean invoices, delivery proof, ledger confirmations and an unambiguous demand notice are what admission turns on.
