Opposing a Winding-Up Petition on a Disputed Debt: The Legal Process Explained

A winding-up petition is the most serious debt enforcement step available to a creditor under English law, and any company served with one should treat it as urgent. However, the courts have repeatedly made clear that the insolvency jurisdiction exists to deal with companies that cannot pay debts which are not in dispute, it is not a forum for resolving genuine commercial disagreements about whether money is owed at all. Where the petition debt is genuinely disputed on substantial grounds, presenting or persisting with the petition is, in the courts’ own language, an abuse of process, and there is a well-established route to have it dismissed before it causes lasting commercial damage.

This article explains, step by step, how a company can oppose a winding-up petition on a genuinely disputed debt, the legal test the courts apply, the leading authorities behind it, and the timetable directors need to follow. Our insolvency litigation team, based in Middle Temple, London, regularly acts for companies and directors facing disputed petitions from trade creditors and HMRC, often at very short notice.

Disputed Debt Winding-Up Petitions at a Glance

1. A petition is served, asserting a specific debt as due and unpaid.
2. The company reviews the alleged debt and identifies a genuine dispute, for example, a contractual defence, a billing error, or an ongoing tax appeal.
3. The company writes to the petitioner (or its solicitors) setting out the grounds of dispute and asking it to withdraw the petition.
4. If the creditor refuses, the company applies urgently to restrain advertisement of the petition in the London Gazette before any bank account freeze takes effect.
5. The company files and serves a witness statement in opposition not less than five business days before the hearing, under rule 7.16(1) of the Insolvency (England and Wales) Rules 2016.
6. At the hearing, the court does not try the underlying dispute itself. If satisfied that a genuine dispute exists, it will normally dismiss or strike out the petition, usually with costs against the petitioner.
7. The creditor remains free to pursue the disputed debt by an ordinary court claim if it chooses to do so.

Why a Disputed Debt Should Never Reach a Winding-Up Hearing

The principle is long-standing. In Mann v Goldstein [1968] 1 WLR 1091, the court held that the winding-up jurisdiction “is not for the purpose of deciding a disputed debt” and that invoking it where the debt is disputed on substantial grounds is an abuse of process. The reasoning is rooted in standing: only a “creditor” may present a winding-up petition, and a party whose entitlement to the debt is genuinely in question has not yet established that status. The Court of Appeal endorsed this in Stonegate Securities Ltd v Gregory [1980] 1 WLR 894, and again in Cornhill Insurance plc v Improvement Services Ltd [1986] 1 WLR 114, confirming that an ordinary civil claim, not insolvency proceedings, is the correct forum for a genuinely disputed debt, regardless of the size of either party.

The policy reason is straightforward. Winding-up proceedings are a collective, summary process for the benefit of creditors once insolvency is established; they are not equipped for the disclosure and cross-examination a contested debt may require. Using the threat of compulsory liquidation, with its frozen bank accounts and reputational fallout, to pressure payment of a properly disputed debt is exactly what the courts have guarded against for decades.

What Counts as a “Genuine Dispute on Substantial Grounds”?

Not every assertion that a debt is “disputed” will succeed. The company must show more than an honestly held belief; it must put forward evidence capable of demonstrating a real, triable issue. In Re a Company (No. 0012209 of 1991) [1992] 1 WLR 351, the court confirmed that the dispute must be substantial rather than insubstantial, and the more recent decision in Just Trays Ltd v Emu Products Ltd [2024] EWHC 29 (Ch) reaffirmed that a credible, evidenced dispute will justify restraining advertisement of the petition pending resolution of that dispute.

Common examples of a genuine disputed debt include:

• A contractual defence, for example, an allegation that goods or services were defective, late, or not provided as agreed.
• A billing or accounting error, including disputes over the correct contractual rate, retentions, or VAT treatment.
• An HMRC assessment based on incorrect figures, or one that is the subject of a live appeal to the First-tier Tax Tribunal.
• A debt that has already been compromised, paid, or is subject to an agreed but unfinalised settlement.

It is worth distinguishing a disputed debt from a cross-claim or set-off. Where a company accepts that money is owed but asserts a genuine and serious cross-claim of its own that equals or exceeds the petition debt, a different (though related) line of authority applies, established in Re Bayoil SA [1999] 1 WLR 147. The practical effect is often similar, dismissal or restraint of the petition, but the legal analysis, and the evidence required, differs. Our companion article on when a counterclaim can defeat a winding-up petition explains that cross-claim route in detail.

Step-by-Step: How to Oppose a Winding-Up Petition on a Disputed Debt

Step 1: Act immediately. Time matters most. A petition is typically advertised in the London Gazette shortly after service, and once advertised, banks routinely freeze company accounts. Specialist advice should be sought the same day a petition comes to light.

Step 2: Marshal the evidence of dispute. Gather contemporaneous correspondence, contracts, invoices and, in tax cases, any notice of appeal or tribunal correspondence. This evidence is decisive; a bare denial will not succeed.

Step 3: Notify the petitioner and request withdrawal. A clear letter setting out the grounds of dispute and inviting withdrawal of the petition should be sent without delay, creating a paper trail that assists later on costs.

Step 4: Apply to restrain presentation or advertisement. If the creditor will not withdraw, an urgent application for an injunction restraining presentation or restraining advertisement is usually the most effective protective step, supported by Dennis Rye Ltd v Bolsover District Council [2009] EWCA Civ 372 as to the court’s willingness to grant such relief on properly evidenced disputes.

Step 5: Consider a validation order if accounts are already frozen. A validation order under section 127 of the Insolvency Act 1986 can permit specific payments or ongoing trading while the dispute is resolved.

Step 6: File and serve the witness statement in opposition. This must reach the court and the petitioner not less than five business days before the hearing, under rule 7.16(1) of the Insolvency (England and Wales) Rules 2016, setting out with supporting documents exactly why the debt is genuinely disputed on substantial grounds.

Step 7: Attend the hearing. The Insolvency & Companies Court will not generally try the underlying dispute itself. Where satisfied a genuine dispute exists, it will normally dismiss or strike out the petition, often with costs against the petitioner, leaving the creditor to bring an ordinary claim if it wishes to pursue the debt.

Key Case Law on Disputed Debts and Winding-Up Petitions

The principles summarised above derive from a consistent line of authority spanning several decades:

• Mann v Goldstein [1968] 1 WLR 1091: established that presenting a winding-up petition over a debt bona fide disputed on substantial grounds is an abuse of process.
• Stonegate Securities Ltd v Gregory [1980] 1 WLR 894 (CA): the Court of Appeal approved and applied the Mann v Goldstein reasoning.
• Cornhill Insurance plc v Improvement Services Ltd [1986] 1 WLR 114 (CA): confirmed that a genuinely disputed debt should be litigated by ordinary action, not by winding-up petition.
• Re a Company (No. 0012209 of 1991) [1992] 1 WLR 351: the dispute must be substantial, not merely asserted.
• Re Bayoil SA [1999] 1 WLR 147 (CA): the leading authority on the related, but distinct, cross-claim/set-off line discussed above.
• Dennis Rye Ltd v Bolsover District Council [2009] EWCA Civ 372: confirms the court’s willingness to grant injunctive relief restraining presentation where a substantial dispute is properly evidenced.
• Just Trays Ltd v Emu Products Ltd [2024] EWHC 29 (Ch): recent confirmation that a credible, evidenced dispute justifies restraining advertisement pending resolution.

HMRC Petitions Based on a Disputed Tax Debt

HMRC presents a substantial proportion of all winding-up petitions, and tax debts are not immune from the disputed debt principle. Where an assessment rests on incorrect figures, a Time to Pay negotiation has broken down unfairly, or most significantly, the taxpayer has a live appeal before the First-tier Tax Tribunal, a genuine and substantial dispute can be just as effective against HMRC as against any other creditor. Courts have shown a willingness to treat a properly constituted tribunal appeal as strong evidence that the underlying liability is not yet established, and will often adjourn or dismiss a petition pending the tribunal’s determination. Our HMRC winding-up petition guidance and overview of HMRC debt escalation cover the wider enforcement picture.

Costs Risk and the Danger of Getting it Wrong

Pursuing a petition over a debt known, or which ought reasonably to have been known, to be genuinely disputed carries a real costs risk for the petitioner, who may face an indemnity costs order where the petition amounts to an abuse of process. Equally, a company that ignores a petition or misses the five business day deadline under rule 7.16 risks losing the ability to oppose at all, and a winding-up order can follow even where a genuine dispute existed but was never placed before the court. Where a director suspects that earlier advice, from an accountant, solicitor or insolvency practitioner, fell short of the standard reasonably expected and caused an avoidable winding-up order, that may itself give rise to a professional negligence claim, which our professional negligence team can advise on.
