How to Reply to a Section 8 Demand Notice and Defend a Section 9 IBC Application: The Pre-Existing Dispute Guide (2026)

Last Updated: August 2026 | Global Vision Law Firm — New Delhi | ~6 min read

A Section 8 demand notice just arrived at your company’s registered office.

An operational creditor — a supplier, a contractor, a service provider — is claiming you owe them money. They have given you 10 days to either pay or raise a dispute.

If you do neither in 10 days, they file a Section 9 CIRP petition before NCLT. If that petition is admitted, a moratorium freezes your company’s operations, your management is suspended, and an Insolvency Resolution Professional takes control.

The 10-day window is your most important window in this entire process. What you do — and how you do it — in these 10 days determines whether you avoid CIRP entirely or face an admission hearing at NCLT.

The legal tool that prevents Section 9 admission is the pre-existing dispute defence. It is the most powerful, most misunderstood, and most commonly mis-executed defence available to a corporate debtor under the IBC.

This guide explains it completely — the legal standard, the step-by-step response process, what makes a dispute “pre-existing” vs “manufactured,” the most current 2026 Supreme Court ruling, and the specific mistakes that turn a valid defence into a dismissed one.

📌 Quick Answer

When a company receives a Section 8 IBC demand notice, it must within 10 days either pay the claimed amount or notify the operational creditor of a pre-existing dispute — a genuine dispute that existed before the demand notice was received. If a plausible pre-existing dispute is established, NCLT must reject the Section 9 petition at the admission stage — without examining the merits of the dispute. The April 2026 Supreme Court ruling in GLS Films Industries v. Chemical Suppliers India (2026 INSC 344) reaffirmed: NCLT only examines whether a plausible dispute exists — not whether it will succeed. Global Vision Law Firm handles Section 9 IBC defence and pre-existing dispute applications before NCLT Delhi. Contact us immediately — the 10-day window cannot be extended.

💔 Two Contrasting Stories — Same Notice, Completely Different Outcomes

Story 1 — Rajesh: Valid Defence, Wrong Execution. CIRP Admitted.

Rajesh’s manufacturing company received a Section 8 demand notice for ₹1.8 crore from a chemical supplier. The claim was disputed — Rajesh’s company had raised quality complaints about the chemical batches in emails 6 months earlier.

But Rajesh’s response to the Section 8 notice was a simple email saying: “We don’t agree with your claim. We will discuss this.” No documents attached. No specific dispute articulated. No reference to the prior quality complaints.

The supplier filed Section 9. At admission, NCLT found the response inadequate — it showed no “plausible pre-existing dispute” supported by material. CIRP was admitted.

Story 2 — Meera: Same Facts, Correct Execution. Section 9 Dismissed.

Meera’s company received a similar notice — ₹1.4 crore claimed by a fabric supplier. Quality disputes had been raised in emails 4 months before the notice.

Global Vision Law Firm structured Meera’s Section 8 reply within 48 hours:

Referenced specific email threads dated before the demand notice
Attached the quality complaint emails, return notes, and survey reports
Quantified the counter-claim — ₹42 lakh in defective goods returned
Filed a civil suit for damages in Commercial Court simultaneously
Sent the reply to the supplier’s registered office by RPAD

At admission, NCLT found a plausible pre-existing dispute — supported by prior correspondence and contemporaneous documentation. Section 9 was rejected. GLS Films (2026 INSC 344) was cited.

Same underlying facts. Same quality dispute. Completely different outcomes — because of how the dispute was documented and communicated.

⚖️ Part 1: The Legal Standard — What Is a “Pre-Existing Dispute” Under IBC?

The Statutory Basis — Sections 8 and 9 of IBC 2016

Section 8(1) requires the operational creditor to send a demand notice before filing a Section 9 petition. The corporate debtor then has 10 days to respond.

Section 8(2) provides the corporate debtor’s two options within 10 days:

Option A: Bring proof that the operational debt has been paid
Option B: Bring to the operational creditor’s notice the existence of a dispute or the record of a pending suit or arbitration proceeding about the claimed debt

Section 9(5)(ii)(d) mandates NCLT to reject a Section 9 application if there exists a “dispute” as defined in Section 5(6) of the IBC.

Section 5(6) IBC defines “dispute” to include:

A suit or arbitration proceeding relating to the existence of the debt
The quality of goods or service
The breach of a representation or warranty

The Supreme Court’s Definitive Legal Standard

The landmark ruling establishing the pre-existing dispute standard: Mobilox Innovations Private Limited v. Kirusa Software Private Limited [(2018) 1 SCC 353] — where the Supreme Court held that NCLT only needs to ascertain whether a plausible dispute exists — not adjudicate the merits.

The most current restatement — April 9, 2026:

<cite index=”19-1″>In GLS Films Industries Private Limited v. Chemical Suppliers India Private Limited (2026 INSC 344), the Supreme Court held that where a plausible pre-existing dispute exists between the parties, which is not spurious, hypothetical, or illusory, the NCLT must reject the application for initiation of the CIRP. The NCLT is only required to examine the existence of such dispute, not its merits.</cite>

<cite index=”15-1″>The Supreme Court stated: “All that is required is for the adjudicating authority to satisfy itself as to the existence of a plausible pre-existing dispute, which was not spurious, hypothetical or illusory. Whether the party raising that dispute would succeed on the strength thereof is not within the ken of such inquiry.”</cite>

The critical practical implication: NCLT cannot conduct a mini-trial on whether your dispute is valid. It cannot assess whether you will ultimately succeed. It only examines whether a real, documented dispute existed before the demand notice was served. If yes — Section 9 must be rejected.

The Four-Part Test for “Plausible Pre-Existing Dispute”

Synthesising the Supreme Court and NCLAT decisions through 2026, a pre-existing dispute must satisfy four requirements:

1 — Pre-existence: <cite index=”17-1″>For a dispute to be considered as “pre-existing”, it should have existed prior to the receipt of the demand notice under Section 8(1) of the Code.</cite>

2 — Plausibility: <cite index=”17-1″>The dispute should be prima facie bona fide and exist naturally in a given fact. The grounds for alleging the existence of a dispute should not be spurious, hypothetical, illusory or misconceived.</cite>

3 — Documentation: The dispute must be supported by contemporaneous material — prior correspondence, complaints, return notes, emails — not invented after the demand notice arrived.

4 — Nexus to the claimed debt: <cite index=”21-1″>The pre-existing dispute must relate to the transaction or debt that forms the basis of the Section 9 application.</cite> A dispute about an unrelated transaction does not protect against a Section 9 petition for a separate, undisputed debt.

🛠️ Part 2: The Step-by-Step Roadmap — How to Respond

Step 1 — Receive and Verify the Section 8 Notice (Day 1)

The moment a Section 8 demand notice arrives — physically or by email at the registered office — the 10-day clock starts. Do not delay. Call your NCLT lawyer immediately.

Verify the notice for technical defects simultaneously with preparing your dispute response:

✅ Was the notice sent to your MCA21 registered office address? A notice sent to an operational office or factory — but not the registered office — may be technically defective. This is an independent ground to challenge Section 9 at admission.

✅ Is the notice in prescribed Form 3 under the IBC (Application to Adjudicating Authority) Rules, 2016? A notice not in prescribed form may be defective.

✅ Does the notice correctly identify the operational debt — with invoice-wise details? A vague notice claiming a round sum without specifics is challengeable.

✅ Is the notice signed by an authorised person of the operational creditor?

Technical defects in the notice are independent grounds to reject Section 9 at admission — document them in your reply even if you also have a substantive dispute.

Step 2 — Audit Your Dispute Evidence (Day 1–2)

Before drafting a single word of the Section 8 reply, conduct a comprehensive audit of your dispute evidence. The dispute must be pre-existing — documented before the notice arrived.

Evidence audit checklist:

Evidence Type	What to Look For	Why It Matters
Quality complaints	Emails, letters, WhatsApp citing defective goods or substandard service — dated before the notice	Direct evidence of pre-existing dispute about quality
Return/rejection notes	Delivery rejection notes, quality inspection reports, return challans	Contemporaneous documents showing goods were disputed at receipt
Reconciliation emails	Any email requesting account reconciliation or disputing the outstanding amount	Shows the amount itself was pre-existing disputed
Legal notices sent by you	Any legal notice or demand sent to the supplier about defective goods or breach	Strong pre-existing dispute evidence
Civil suit or arbitration filed by you	Any prior suit or arbitration about this supplier/transaction	Section 5(6) specifically includes pending suits
Payment stop communications	Any internal or external communication explaining why payment was withheld	Contemporaneous evidence of dispute motivation
Police complaints	<cite index=”20-1″>Before issuance of a demand notice by the Respondent, the Appellant had lodged a complaint with the police alleging coercive tactics — NCLT refused to admit the application, citing a pre-existing dispute</cite>	Even police complaints about coercive recovery tactics can constitute a pre-existing dispute

Step 3 — Draft the Section 8 Reply (Day 2–7)

The Section 8 reply is your most important document in this entire defence. It must be sent to the operational creditor’s registered address within 10 days.

Structure of an effective Section 8 reply:

Part A — Notice Defects (if any): State specifically any defects in the notice — wrong address, wrong form, incorrect debt particulars, unauthorised signatory. These are independent grounds for Section 9 rejection.

Part B — Declaration of Dispute: Clearly state that a dispute exists regarding the claimed operational debt — citing the specific nature of the dispute (quality, quantity, breach of warranty, pricing, reconciliation).

Part C — Chronological Dispute Narrative: Provide a timeline of events establishing that the dispute pre-dates the notice:

Date of supply/service
Date when defects/dispute was first noticed
Date and content of each prior communication raising the dispute
Current status of the dispute

Part D — Documents Annexed: Attach every pre-existing dispute document — the emails, complaint letters, return notes, survey reports, legal notices, FIR copies (if any). Every document referenced in the reply must be annexed.

Part E — Counter-Claim (if applicable): If your company has a counter-claim against the supplier — for defective goods, for damages, for breach of contract — state it specifically with quantum. A counter-claim is strong evidence of a genuine pre-existing dispute.

Part F — Denial of Debt Quantum: Even if some amount may be owed — if the specific amount claimed in the notice is disputed (different calculation, credit notes not accounted for, deductions for defective goods), state the denial of quantum specifically.

Sending the reply:

Send by RPAD (Registered Post with Acknowledgement Due) to the supplier’s registered office address
Send simultaneously by email to all known email addresses
Keep comprehensive evidence of dispatch and delivery

Step 4 — File a Civil Suit or Invoke Arbitration Simultaneously (Day 1–10)

<cite index=”17-1″>Courts have cautioned debtors against raising the plea of pre-existing dispute as a moonshine defence.</cite>

The most effective way to demonstrate that your dispute is genuine — not manufactured to avoid CIRP — is to file an affirmative legal action:

Option A — Civil Suit in Commercial Court: File a civil suit against the operational creditor for damages arising from defective goods, breach of contract, or whatever the underlying dispute is. A suit filed contemporaneously with or before the Section 8 reply is powerful evidence that the dispute is genuine.

Note: <cite index=”18-1″>The evidentiary value of a civil recovery suit filed by the appellant in April 2022 was refused in GLS Films as a post-initiation event.</cite> This underscores the critical importance of filing the suit before the Section 9 petition is filed — ideally simultaneously with or before the Section 8 reply.

Option B — Invoke Arbitration: If the supply agreement has an arbitration clause — invoke arbitration for the dispute about defective goods or non-payment. A pending arbitration proceeding relating to the same transaction is specifically included in Section 5(6)’s definition of “dispute.”

Option C — File a Complaint with Quality Authorities: If the dispute is about product quality — a complaint to the Bureau of Indian Standards, relevant sectoral authority, or consumer forum creates contemporaneous evidence of the dispute’s genuineness.

Step 5 — Prepare for Section 9 Admission Hearing (If Petition Is Filed)

Even after a properly filed Section 8 reply — the operational creditor may still file a Section 9 petition. Prepare for the admission hearing:

What you present at admission:

The Section 8 notice and its defects (if any)
Your Section 8 reply and proof of dispatch
All pre-existing dispute documents
Evidence of any civil suit, arbitration, or affirmative legal action filed
A concise written submission citing GLS Films (2026 INSC 344) and Mobilox (2018) — demonstrating that a plausible pre-existing dispute exists and NCLT cannot go into its merits

What NCLT examines at admission: NCLT does not conduct a trial. It does not examine whether your quality complaint will ultimately succeed. <cite index=”15-1″>All that is required is for the adjudicating authority to satisfy itself as to the existence of a plausible pre-existing dispute, which was not spurious, hypothetical or illusory.</cite>

Your target at admission: produce enough documented evidence that NCLT is satisfied a plausible dispute exists — and cannot be persuaded that your dispute is spurious or manufactured.

⚠️ Part 3: What Makes a Dispute “Pre-Existing” vs “Moonshine” — The Critical Distinction

Pre-Existing Disputes That NCLT Accepts

✅ Quality complaints in emails before the demand notice — the most common and most accepted form ✅ Account reconciliation requests — where the amount itself is disputed in prior correspondence ✅ Return notes and rejection challans — contemporaneous documents at the time of supply ✅ Legal notices about defective goods — sent before the demand notice arrived ✅ Pending civil suits or arbitration — about the same transaction or relationship ✅ Pending police complaints — particularly about coercive recovery tactics used by the creditor ✅ Survey/inspection reports — technical reports documenting quality defects

“Moonshine” Defences That NCLT Rejects

❌ Disputes raised for the first time in the Section 8 reply — with no prior documentation ❌ Vague quality complaints without specific dates, specific invoices, or specific defects identified ❌ Round-sum denials — “we don’t owe this amount” without explanation or documentation

<cite index=”15-1″>The respondent’s belated reply followed by its multiple debit notes for interest in quick succession were just afterthoughts to build up a case to file an application under Section 9.</cite> This is what courts characterise as a moonshine defence — manufactured after receiving the demand notice, not genuinely pre-existing.

❌ Civil suits filed after the Section 9 petition — <cite index=”18-1″>the evidentiary value of a civil suit filed as a post-initiation event is refused.</cite> ❌ Disputes about unrelated transactions — the dispute must relate to the specific debt claimed in the notice

The Recent NCLT Rejection — August 2026

<cite index=”16-1″>NCLT Chandigarh, in a ruling published just 2 days ago, admitted a Section 9 petition after rejecting the corporate debtor’s pre-existing dispute defence — holding that the respondents had failed to prove or place on record any material to establish the existence of a plausible pre-existing dispute. The tribunal noted that there should be a plausible pre-existing dispute that existed before the issuance of the demand notice, and the respondents’ failure to produce contemporaneous documentary evidence led to the rejection of the defence.</cite>

This August 2026 ruling confirms that courts are actively distinguishing between genuine pre-existing disputes supported by documentation and manufactured defences unsupported by prior evidence.

📊 Pre-Existing Dispute Defence — Strength Assessment

Your Evidence	Dispute Strength	NCLT Likely Outcome
Prior emails + quality complaints + civil suit filed simultaneously	Very Strong	Section 9 rejected at admission
Prior emails with quality complaints — no civil suit	Strong	Section 9 likely rejected
Account reconciliation request in prior email	Strong	Section 9 likely rejected
Prior legal notice sent to supplier about defects	Strong	Section 9 likely rejected
Pending arbitration about same transaction	Very Strong	Section 9 rejected (Section 5(6) explicitly)
Police complaint before demand notice	Strong	Section 9 likely rejected
Dispute raised only in Section 8 reply — no prior documentation	Weak (Moonshine risk)	Section 9 likely admitted
Vague denial with no documents	Very Weak	Section 9 admitted

🔑 Part 4: Defending at NCLT Admission — If Section 9 Is Still Filed

Even with a robust Section 8 reply, the operational creditor may file Section 9. The admission hearing before NCLT is your next critical opportunity.

What to File Before the Admission Hearing

Written Reply / Counter-Affidavit: A formal written submission setting out:

Technical defects in the Section 8 notice (if any)
The pre-existing dispute — chronological narrative with all documents
The Section 8 reply and proof of dispatch
Any civil suit, arbitration, or complaint filed
Legal submissions citing GLS Films (2026 INSC 344), Mobilox (2018), S.S. Engineers, and Sabarmati Gas

Application for Rejection Under Section 9(5): A specific application citing Section 9(5)(ii)(d) — requesting rejection because a pre-existing dispute exists.

The Legal Argument at Admission

The core submission: <cite index=”19-1″>”The NCLT’s role at the admission stage is limited to determining whether a plausible dispute exists. The Court is not required to assess the merits or likely success of the defence. If the dispute is not patently feeble or unsupported by evidence, the application under Section 9 must be rejected.”</cite>

The NCLAT principle from R.A.J. Krishna Construction that applies: <cite index=”21-1″>The dispute raised must be truly existing at the time of filing a reply to the notice of demand as contemplated by Section 8(2) of IBC or at the time of filing the Section 9 application.</cite>

The NCLAT ruling supporting email-based dispute evidence: <cite index=”22-1″>NCLAT ruled that a Section 9 IBC petition is not maintainable when email exchanges and unreconciled accounts show a pre-existing dispute between parties.</cite>

If NCLT Admits Despite Your Defence

If NCLT admits the Section 9 petition despite a genuine pre-existing dispute — file an NCLAT appeal within 30 days of the admission order. The appeal must be filed and an urgent stay of the NCLT’s admission order must be obtained — because the moratorium and IRP appointment flow automatically from admission.

<cite index=”20-1″>Setting aside the NCLAT’s decision in GLS Films, the Supreme Court noted that NCLAT erred in going into the merits of the dispute, ignoring the restriction imposed under the Code to only identify whether there existed a plausible dispute.</cite> This precedent is available to you in NCLAT if NCLT wrongly assessed the merits rather than merely the existence of your dispute.

❓ Quick FAQs — What Companies Actually Search

Q: What is the 10-day window under Section 8 IBC and can it be extended? A: Under Section 8(2) IBC, a corporate debtor has 10 days from receipt of the Section 8 demand notice to either pay the claimed amount or raise a pre-existing dispute. This 10-day window cannot be extended. If neither action is taken within 10 days — the operational creditor can file a Section 9 CIRP petition immediately. This is the most unforgiving deadline in the entire IBC framework.

Q: What makes a pre-existing dispute “genuine” vs “manufactured” under IBC? A: A genuine pre-existing dispute is documented in prior correspondence — emails, letters, return notes, legal notices — that pre-date the Section 8 demand notice. A manufactured dispute is one raised for the first time in the Section 8 reply, with no prior documentation. Courts call the latter a “moonshine defence” and reject it. The distinction is entirely evidential — what contemporaneous documents exist that pre-date the notice?

Q: Can I file a civil suit after receiving a Section 8 notice to create a “pre-existing dispute”? A: The civil suit itself must be filed before the Section 9 petition is filed to have maximum evidentiary weight. The Supreme Court in GLS Films (2026) noted that a suit filed after the Section 9 application was initiated had reduced evidentiary value. File the civil suit simultaneously with or before the Section 8 reply — not after Section 9 is filed.

Q: The Section 8 notice was sent to our factory, not our registered office. Can we challenge Section 9 on this ground? A: Yes — a Section 8 demand notice must be served at the corporate debtor’s registered office address as recorded in MCA21. A notice served at an operational address, factory, or branch — but not the MCA21 registered office — may be technically defective, making the Section 9 petition premature or not maintainable. Raise this in your Section 8 reply and at NCLT admission.

Q: We have a quality dispute but didn’t raise it before the demand notice. Can we still defend? A: It becomes significantly harder. The pre-existing dispute must genuinely pre-date the notice. However, if there is any prior documentary evidence — even an internal email, a purchase return note, or a conversation WhatsApp message — that references the quality issue before the notice was received, that document becomes your evidence. Conduct a thorough evidence audit immediately and present whatever contemporaneous material exists.

Q: What happens if NCLT admits the Section 9 petition despite our pre-existing dispute defence? A: File an NCLAT appeal within 30 days and simultaneously seek a stay of the NCLT’s admission order. The stay prevents the moratorium and IRP appointment from taking effect while the appeal is heard. Cite GLS Films (2026 INSC 344) — if NCLT went into the merits of your dispute rather than merely assessing its plausible existence, that is a legal error that NCLAT can correct.

Q: Can a Section 9 petition be filed even if there is a pending arbitration between the parties? A: No — a pending arbitration proceeding relating to the existence of the debt, the quality of goods, or the breach of a warranty is expressly included in Section 5(6)’s definition of “dispute.” If you have a pending arbitration about the same transaction, NCLT must reject the Section 9 petition at admission. Ensure the arbitration was invoked before the demand notice was received for maximum effect.

💡 Final Thought

The Section 8 demand notice is not just a demand for payment. It is the starting gun for a process that — if not handled correctly in the next 10 days — can end in CIRP admission, management suspension, and IRP appointment at your company.

The pre-existing dispute defence is your most powerful tool. The April 2026 Supreme Court ruling in GLS Films (2026 INSC 344) has definitively settled the standard: NCLT only examines whether a plausible dispute exists — it cannot conduct a mini-trial on whether you will succeed.

But that defence only works if it is genuinely documented, chronologically established, and properly communicated in the Section 8 reply — within the 10-day window that cannot be extended.

Rajesh had a valid dispute. He communicated it wrongly. CIRP was admitted.

Meera had the same dispute. She communicated it correctly. Section 9 was dismissed.

The law gives you the tool. The quality of execution determines whether it works.
