Vexatious Litigants in the UK: What Small Businesses Should Know to Protect Themselves

If you run a small business, chances are you’ve dealt with the odd customer dispute or supplier disagreement. But what if you come up against someone who takes things to extremes-constantly threatening you with legal action, filing multiple frivolous claims, or dragging your company through the courts again and again?

This isn’t just frustrating and expensive-it could be a sign you’re dealing with a vexatious litigant. Vexatious litigation is a growing issue for many UK businesses, from retailers and franchisees to online service providers. So, how can you spot the warning signs, what legal protections exist, and what can you do if you think someone is launching vexatious claims against your company?

In this practical guide, we’ll walk through what a vexatious litigant is in the UK, how vexatious litigation can affect small businesses, and what steps you can take to protect your business, including how to get someone declared a vexatious litigant.

What Is a Vexatious Litigant in the UK?

Let’s start from the top. A vexatious litigant is someone who persistently brings legal action without reasonable grounds, mainly to harass or subdue their target-like a business owner, staff member, or another organisation.

In practice, this could mean someone:

• Repeatedly suing your company over trivial issues, even after courts have dismissed their claims
• Filing multiple complaints with regulators, often with little or no evidence
• Using legal threats as a bargaining tool to gain free services or refunds they aren’t entitled to
• Taking your business to court for issues that have already been rejected or settled

Vexatious litigation creates a huge drain on time, money, and mental energy-especially for small businesses. The UK’s legal system has recognised this issue, and there are specific mechanisms in place to limit vexatious claims and even restrict individuals who abuse the system from starting new court cases without permission.

Why Should Small Businesses Worry About Vexatious Litigation?

Unfortunately, vexatious litigants aren’t just an issue for big corporates. Small businesses are particularly vulnerable for a few reasons:

• Legal costs add up fast-defending even baseless claims is expensive
• Time spent preparing for court, gathering documents, and seeking legal advice takes you away from running your business
• Your business reputation may take a hit if complaints or claims are publicised online or in the media
• Frequent complaints can attract the scrutiny of regulators, or trigger audits and investigations
• If you’re a startup or family-run business, just one persistent vexatious claim can be overwhelming

That’s why understanding the warning signs-and knowing what steps to take if you’re targeted-can save you both money and anxiety in the long run.

What Counts as Vexatious Litigation in the UK?

Not every claim against your business is vexatious. UK courts and regulators are clear: people have a right to pursue complaints and legal action if they genuinely believe they’ve been wronged. You can’t (and shouldn’t) block legitimate claims, and some disgruntled customers or suppliers may have real grievances.

However, vexatious litigation generally involves:

• Legal claims brought solely or mainly to harass, cause delay, or force a settlement, rather than resolve a genuine legal dispute
• Repeated complaints or lawsuits, often after previous cases have been dismissed as groundless
• Misuse of legal processes-such as filing in the wrong court or making wild accusations without evidence
• Ignoring judgments or continuing to raise previously rejected issues

If a pattern emerges-or if a court officer, judge, or regulator notices a string of repetitious, baseless complaints-they may start to act to protect businesses like yours.

How Does the Vexatious Litigant UK List Work?

In England and Wales, the Attorney General maintains an official “vexatious litigants” list. Individuals on this list have been subjected to a “Civil Proceedings Order” by the High Court under section 42 of the Senior Courts Act 1981.

This means they cannot start any further legal proceedings in a UK court or tribunal without first getting permission from a high court judge. If someone keeps dragging your business through the courts for the same issues, or with obviously unfounded claims, they may end up on this list.

How to Get Someone Declared a Vexatious Litigant?

Getting someone declared a vexatious litigant isn’t automatic, and you can't generally apply for it yourself as a business owner. Instead, it's usually the Court itself, the Attorney General, or a public body (like HMRC or a regulator) that applies for this type of order, generally after multiple complaints from the same individual across different cases.

Here’s how the process usually works:

1. Document the Pattern: Keep careful records of all litigation and complaints made by the individual against your business.
2. Defend Claims Properly: Defend each claim robustly with professional legal help-even if the claim seems frivolous. Courts will look at how your business has responded.
3. Raise the Issue with Your Lawyer: If you think a new claim is part of a broader pattern of vexatious behaviour, flag this to your solicitor and ask if the court can be notified.
4. Court Consideration: If the court sees evidence of repeated, groundless, or abusive litigation, it can make a “Civil Proceedings Order” to restrict further legal actions by that individual.

While your business usually cannot directly apply for a vexatious litigant order, documenting every interaction, claim, and court hearing establishes the pattern needed for the courts to take action.

What Can You Do If Your Business Is Targeted by Vexatious Claims?

If you believe your business is the target of vexatious claims or litigation, you can take practical steps to protect yourself:

• Keep Thorough Records: Store all contracts, correspondence, invoices, and complaint-handling records. This makes defending each claim much easier, and helps establish a pattern for the courts if needed.
• Respond Professionally: Even if a claim is baseless, maintain a professional tone in all responses. Don’t be drawn into arguments or make aggressive counter-threats.
• Engage a Solicitor Early: Legal costs can mount quickly-seek professional advice as soon as you notice a potential pattern of vexatious claims. Solicitors experienced in business claims can help you cut through red tape and push for stronger court or regulatory interventions if needed.
• Apply for Costs or Strike-Outs: If you can show a claim is totally baseless and/or part of a pattern, courts may allow you to apply to have it ‘struck out’ or to recover your legal costs.
• Monitor Online Reputation: Vexatious complainants often post multiple negative reviews as well as legal threats. Take practical steps to address online reviews, and keep evidence of repeated malicious reviews in case of legal escalation.
• Practice Proactive Risk Management: Review your business contracts and legal documents-clear terms and conditions, robust refund policies, and strong dispute resolution clauses make it harder for vexatious claims to gain traction.

Recognising Vexatious Claims: Warning Signs and Examples

So, how do you spot the difference between a difficult customer and genuine vexatious litigation? Warning signs include:

• The same individual or organisation has brought repeated claims against your business-even after the courts or regulators have dismissed them as groundless
• Legal claims seem mainly aimed at pressuring you into giving compensation, “hush money,” or a settlement out of fear, rather than truly addressing a loss
• There is a pattern of irrelevant or extreme allegations, especially if they are unsupported by real evidence
• The claimant ignores mediation or ADR (alternative dispute resolution), always insisting on court action
• The individual files almost identical claims against your business, simply changing dates or amounts

Vexatious claims can cover almost anything, from refund demands and data privacy complaints to property disputes, franchise arguments, or IP infringement. For further reading on spotting and responding to contract breach claims, check our step-by-step guide for businesses.

What Legal Protections Exist for Small Businesses?

If you’re being targeted with vexatious litigation in the UK, several legal protections and remedies may apply:

• Civil Restraint Orders: Courts may issue civil restraint orders against someone who repeatedly issues claims that are totally without merit. These orders can ban them from making any new applications in the courts without first getting permission.
• Costs Orders: If a court finds a claim is without merit or vexatious, you can often ask the judge to order the claimant to pay your legal costs-providing some financial relief.
• Striking Out Baseless Claims: UK courts have powers to ‘strike out’ cases that have no prospect of success, saving you the time and stress of a full trial.
• Reporting to the Attorney General: If the issue is severe, courts or regulators may notify the Attorney General to consider further restrictions on the person-potentially putting them on the vexatious litigant list.
• Alternative Dispute Resolution (ADR): You can often point to a claimant’s refusal to engage in ADR as evidence of unreasonable or vexatious behaviour.

It’s important to note that proactively reviewing your legal documentation and internal processes can prevent many issues before they escalate to the court stage. Consider regular contract reviews and clear engagement terms to reduce the risk of disputes taking hold.

How to Minimise the Risk of Vexatious Claims Against Your Business

No business can fully eliminate the risk of vexatious claims, but you can significantly reduce your risks by putting the right legal foundations in place. Here are practical steps for UK small businesses:

• Have professionally drafted contracts and clear terms of trade: Don’t rely on generic templates-make sure your contracts are tailored to your goods, services, and business structure. See our guide on why ‘copy and paste’ contract templates cause problems.
• Train your staff in fair dispute handling: Equip your team with procedures for dealing with customer complaints in a fair, consistent way. Good records help show courts or regulators you’ve acted reasonably.
• Seek legal advice at the first sign of trouble: Don’t wait until a third or fourth claim hits-early intervention by a solicitor can stop many vexatious cases before they balloon.
• Keep up with changes in consumer and data protection law: This helps you avoid falling foul of technicalities that vexatious litigants sometimes exploit. Our consumer law compliance guide provides a helpful starting point.
• Familiarise yourself with available dispute resolution tools: Consider mediation, arbitration, and ombudsman services for recurring issues-often a faster and cheaper way to resolve problems than going to court.

Can Vexatious Litigation Harm My Business Reputation or Credit?

Yes-vexatious litigation can damage your reputation if the claims are public, or if the claimant spreads false accusations online or in the press. It may also impact your business credit if court actions result in County Court Judgments (CCJs) or repeated legal claims affecting supplier relationships.

This is another reason to address vexatious litigants proactively, maintaining detailed evidence and engaging with professional advisors early.

Are There Special Protections for Startups and Entrepreneurs?

There’s no separate legal process for startups or angel-backed businesses. However, if your startup is newly incorporated or you’re seeking to attract business angel investors, robust legal procedures for handling disputes will boost your credibility. Angel and venture investors (sometimes called ‘business angels’) typically look for companies with solid compliance and risk management processes-meaning they’ll want to see you have contracts, complaint procedures, and a plan for handling litigation risks.
