What Is a Skeleton Argument and How Do I Write One?

If you're representing yourself in court — or even if you have a lawyer and want to understand the process — you'll almost certainly encounter the term "skeleton argument." It's one of the most important documents in litigation, and getting it right can make or break your case.

This guide explains what a skeleton argument is, when you need one, how to structure it, and what judges actually want to see. We cover the rules across three common law jurisdictions: the United Kingdom, Hong Kong, and Australia.

What is a skeleton argument?

A skeleton argument is a concise written document that sets out the key points you intend to make at a court hearing. Think of it as a roadmap for the judge — it tells them what the case is about, what you're asking for, and why you should win, supported by references to the evidence and legal authorities (cases and statutes) you rely on.

The word "skeleton" is important. It's not meant to be a full essay or a detailed narrative of everything that happened. It's a framework — the bones of your argument — that the judge reads before the hearing so they come prepared. The oral submissions at the hearing then put flesh on those bones.

When do you need a skeleton argument?

The rules vary by jurisdiction, but generally you need a skeleton argument for:

• Interlocutory hearings — applications for injunctions, summary judgment, striking out, security for costs, and similar interim applications
• Appeals — almost always required for appeals in all three jurisdictions
• Trials — required for most trials, especially in the higher courts
• Case management conferences — sometimes required, depending on the court's directions

United Kingdom (England & Wales)

Under the Civil Procedure Rules, skeleton arguments are required for most hearings in the High Court and Court of Appeal. Practice Direction 52A requires skeleton arguments for appeals. For trials and interim applications, the court will usually give directions requiring them. The general expectation is that they should be filed and served well in advance of the hearing — typically 2 days before an interim application and 7 days before a trial.

Hong Kong

In the High Court, Practice Direction 5.4 governs skeleton arguments. They are required for most interlocutory applications and trials. The Court of Appeal requires skeleton arguments for all appeals. Filing deadlines are usually set by the court in its directions, but the default expectation is to file well in advance of the hearing to give the judge and the other side time to read them.

Australia

The Federal Court requires written submissions (which serve the same function as skeleton arguments) for most hearings. State supreme courts have similar requirements. In Victoria, for example, Practice Note SC Gen 10 requires written submissions for trials. The terminology varies — some courts call them "written submissions," others "outline of submissions" — but the substance is the same.

How to structure a skeleton argument

While every case is different, a good skeleton argument follows a standard structure. Here's the framework that works across all three jurisdictions:

1. Heading and parties

Start with the case name, court reference number, the hearing date, and what the hearing is about. Make it immediately clear to the judge what they're reading.

2. Introduction (2–3 paragraphs)

Briefly state who you are, what the case is about, and what you're asking the court to do. This should be a clear, punchy summary that the judge can read in 30 seconds and understand the essence of the dispute.

3. Factual background

Set out the key facts — but only the facts that matter for the issues before the court. Don't narrate the entire history of the dispute. Focus on the facts that support your legal arguments. Reference the evidence (witness statements, documents) by paragraph or page number so the judge can find it quickly.

4. Legal framework

State the legal principles that apply. Cite the relevant statutes and case law. You don't need to quote lengthy passages — just identify the authority and the proposition it stands for. If there's a leading case, cite it and explain in one sentence what it establishes.

5. Submissions

This is the core of the skeleton. Apply the legal principles to the facts of your case and explain why you should win. Structure your submissions logically — deal with each issue in turn, and number your paragraphs for easy reference during the hearing.

6. Relief sought

End by clearly stating what orders you're asking the court to make. Be specific — "the Defendant's application should be dismissed with costs" or "the Plaintiff seeks summary judgment in the sum of $X with interest."

Common mistakes to avoid

Having reviewed thousands of skeleton arguments, here are the most common mistakes we see — especially from litigants in person:

• Writing an essay instead of a skeleton. The judge doesn't need your life story. They need to know the legal issues and your best arguments. Cut everything that doesn't directly support a legal point.
• Not citing authorities. Every legal proposition should be supported by a case or statute. Saying "it's obvious" or "it's common sense" doesn't work in court. Judges need authorities.
• Citing too many authorities. The flip side — don't cite 30 cases when 3 strong ones will do. Quality over quantity. The judge won't read all of them anyway.
• Being emotional or argumentative. A skeleton argument is not the place to express how unfair the other side has been. Keep the tone measured, professional, and focused on the law.
• Missing the deadline. Filing late makes a terrible impression. Judges notice, and it can result in cost consequences or your arguments being given less weight.
• Not addressing the other side's arguments. If you know what the other side is going to argue, deal with it in your skeleton. Anticipating and rebutting opposing arguments shows the judge you've thought the case through.

A note on authorities

Citing case law can be intimidating if you're not a lawyer. Here's a practical approach:

• For each legal principle you rely on, identify the leading case — the most authoritative decision from the highest court
• Use the neutral citation format (e.g., [2024] UKSC 1 for UK Supreme Court, [2024] HKCFA 1 for Hong Kong Court of Final Appeal)
• You don't need to quote the entire judgment — just identify the relevant paragraph number and state the principle in your own words
• Courts in these jurisdictions cite each other's decisions. A strong UK authority can be persuasive in Hong Kong and vice versa

What if I can't write one myself?

Many litigants in person struggle with skeleton arguments because they require legal knowledge, analytical skill, and concise writing. If you're finding it difficult, you have options:

• Hire a barrister on a direct access basis — in the UK and Hong Kong, you can instruct a barrister directly (without a solicitor) just to draft your skeleton argument. This is more affordable than full representation.
• Use a legal research service — services like CommonBench can analyse your case and draft skeleton arguments at a fraction of the cost of a barrister, delivered within 24 hours.
• Pro bono assistance — some organisations provide free legal help for litigants in person, though availability is limited.

Summary

A skeleton argument is your chance to make a first impression with the judge — before you even open your mouth in court. Get it right, and you walk into the hearing with the judge already understanding your case. Get it wrong, and you're spending your precious hearing time explaining things that should have been clear from the paper.

The formula is simple: be concise, be structured, cite your authorities, and tell the judge exactly what you want. If you follow the framework in this guide, you'll produce a skeleton argument that any judge would respect.
