Filing Insolvency Against a Customer Under Section 9 IBC

Short answer: Section 9 of the Insolvency and Bankruptcy Code, 2016 (IBC) empowers an 'operational creditor' (a business that has supplied goods or services) to file an application to initiate the Corporate Insolvency Resolution Process (CIRP) against a 'corporate debtor' (a customer company or LLP). This is possible only when there is a clear, undisputed debt and a default of at least ₹1 crore, and after a mandatory demand notice has been served.

Who can file an application under Section 9 of the IBC?

An application under Section 9 can be filed by an 'Operational Creditor'. The IBC defines an operational creditor as any person to whom an 'operational debt' is owed. This primarily includes suppliers of goods, providers of services, employees owed unpaid salaries, and government bodies for statutory dues. The entity you are filing against must be a 'Corporate Debtor,' which means a private limited company, public limited company, or a Limited Liability Partnership (LLP).

What is the minimum default amount required?

The minimum amount of default required to initiate proceedings under Section 9 is ₹1 crore. This threshold was significantly increased from the original limit of ₹1 lakh by the government to prevent the misuse of IBC for smaller defaults and to ensure that only significant cases of financial distress are brought before the National Company Law Tribunal (NCLT). The debt must be a single, undisputed claim of at least this amount.

What is the mandatory first step before filing?

The mandatory first step is to send a demand notice under Section 8 of the IBC. Before approaching the NCLT, the operational creditor must deliver a formal demand notice to the corporate debtor, demanding payment of the defaulted amount. This notice must be sent in either Form 3 (if accompanied by a copy of the invoice) or Form 4 (as prescribed under the IBC rules). The debtor then has 10 days to either pay the amount or notify the creditor of a pre-existing dispute. Failure to do either gives the creditor the right to file a Section 9 application.

What documents are required for a Section 9 application?

Filing an application with the NCLT requires precise and complete documentation. The application is filed in Form 5 and must be accompanied by several key documents:

• A copy of the Section 8 demand notice (Form 3 or Form 4) sent to the corporate debtor.
• Proof of dispatch and delivery of the notice (e.g., speed post receipt, email delivery report).
• An affidavit stating that there is no pre-existing dispute regarding the unpaid operational debt.
• A copy of the invoice or any other document that proves the existence of the debt.
• A copy of your bank statements, certified by the bank, showing that no payment has been received from the debtor.
• Any other correspondence or contracts that support your claim.
• Authorization to file the application, such as a Board Resolution.

What happens after the application is filed?

After the application is filed, the NCLT will scrutinize it for completeness. The NCLT has 14 days to ascertain the existence of the default and admit or reject the application. If the application is complete, the debt is proven, and there is no pre-existing dispute, the NCLT will 'admit' the application. Upon admission, two major things happen: a moratorium is declared under Section 14 of the IBC, which freezes all other legal proceedings against the company, and an Interim Resolution Professional (IRP) is appointed to take over the management of the company. This marks the beginning of the Corporate Insolvency Resolution Process (CIRP).

Section 7 vs. Section 9 Application: Key Differences

Understanding the difference between an application by a financial creditor and an operational creditor is crucial.

Basis	Section 7 Application	Section 9 Application
Who can file?	Financial Creditor (e.g., bank, lender)	Operational Creditor (e.g., supplier, employee)
Minimum Default	₹1 crore	₹1 crore
Demand Notice	Not mandatory	Mandatory under Section 8
Proof Required	Proof of financial debt and default.	Proof of operational debt, default, and no pre-existing dispute.
Initiation by	Financial Creditor(s) individually or jointly.	A single Operational Creditor.
Adjudication Focus	NCLT confirms debt and default from records.	NCLT also verifies the absence of a pre-existing dispute.

Worked example

Let's consider a realistic scenario in Bengaluru.

• Parties: 'Synthwave IT Solutions Pvt. Ltd.' (a Bengaluru-based software vendor) is the Operational Creditor. 'Deccan Logistics Ltd.' is the Corporate Debtor.
• Background: Synthwave provided custom logistics software and maintenance services to Deccan Logistics. Invoices totalling ₹1.35 crore, due between January and June 2026, remain unpaid despite multiple reminders.
• Step 1: Demand Notice: On 1st September 2026, our firm, acting for Synthwave, dispatches a Demand Notice in Form 3 under Section 8 of the IBC. The notice, along with copies of all 12 unpaid invoices, is sent to Deccan Logistics' registered office via speed post and email.
• Step 2: Debtor's Inaction: The 10-day period expires on 11th September 2026. Deccan Logistics neither pays the outstanding ₹1.35 crore nor sends a notice of dispute.
• Step 3: NCLT Application: On 15th September 2026, we prepare and file an application under Section 9 in Form 5 with the NCLT, Bengaluru Bench. The application includes:
  • The Section 9 application on behalf of Synthwave.
  • An affidavit confirming no dispute existed prior to the demand notice.
  • Copies of the service agreement and unpaid invoices.
  • Synthwave's certified bank statement showing no receipt of funds.
  • Proof of delivery of the Section 8 notice.
• Step 4: Admission: The NCLT reviews the documents. It finds a clear operational debt, a default over ₹1 crore, proper service of the demand notice, and no evidence of a pre-existing dispute. The NCLT admits the application, initiates CIRP against Deccan Logistics, and appoints an IRP.

What is a 'pre-existing dispute' and why does it matter?

A 'pre-existing dispute' is a critical defense for a corporate debtor. If the debtor can prove that a genuine dispute about the quality of goods, quantity, service deficiency, or payment terms existed before the Section 8 demand notice was sent, the NCLT must reject the Section 9 application. For example, if the customer had sent emails complaining about software bugs or non-performance before receiving the demand notice, this could constitute a pre-existing dispute. The IBC is a tool for resolving insolvency, not a substitute for debt recovery proceedings where the debt itself is in question. A disputed debt must be settled through other legal means like a civil suit or arbitration.

Common mistakes

1. Filing without Sending a Section 8 Notice: This is a fatal flaw. The demand notice is a mandatory precondition, and an application filed without it will be immediately dismissed.
2. Using IBC for Disputed Debts: Filing a Section 9 application when you know the client has raised legitimate issues about your service/product is an abuse of process and will be rejected.
3. Improper Service of Notice: Failing to serve the demand notice at the registered office of the corporate debtor or not having valid proof of service can lead to dismissal.
4. Incomplete Documentation: Not attaching the affidavit swearing that there is no dispute or failing to provide certified bank statements are common errors that cause delays or rejection.
5. Miscalculating the 10-Day Period: The 10-day period for the debtor to respond is strict. Filing the application prematurely can be a ground for rejection.

Frequently asked questions

Can an individual proprietor file a Section 9 application?

Yes, an individual proprietor or a partnership firm can be an 'Operational Creditor' and file an application under Section 9. However, the application can only be filed against a 'Corporate Debtor,' which is a company or an LLP.

How long does the NCLT take to admit a Section 9 application?

The IBC code stipulates a 14-day timeline for the NCLT to review the application and admit or reject it. However, due to the high volume of cases and procedural requirements, the actual time taken can often be longer.

What is the difference between winding up and CIRP under IBC?

The primary objective of CIRP under the IBC is the resolution and revival of a distressed company as a going concern. Winding up, or liquidation, is the process of selling the company's assets and dissolving it. The IBC prioritizes resolution over liquidation.

Can I file a case if my customer is an individual or a partnership firm?

No. Section 9 of the IBC is only applicable to 'Corporate Debtors' (i.e., companies and LLPs). For recovery of dues from individuals or traditional partnership firms, you would need to file a civil recovery suit, a complaint under the MSME Samadhaan portal, or initiate arbitration if an arbitration clause exists in your contract.
