Introduction

Writing a law assignment requires more than simply describing legal principles. Universities expect students to interpret legislation, analyse case law, construct persuasive legal arguments, and reference every source accurately using the Oxford Standard for the Citation of Legal Authorities (OSCOLA).

Whether you're studying law in the UK, Australia, or another common law jurisdiction, this guide explains how to write a high-quality law assignment using OSCOLA referencing.

What Is a Law Assignment?

A law assignment is an academic assessment that evaluates your understanding of legal principles, legislation, judicial decisions, legal reasoning, and your ability to apply the law to real or hypothetical scenarios.

Common law assignment topics include:

• Contract Law

• Criminal Law

• Tort Law

• Constitutional Law

• Human Rights Law

• Company Law

• Employment Law

• Family Law

• Property Law

• Public Law

• International Law

• Commercial Law

Unlike many university assignments, law assignments require you to support legal arguments using primary legal authorities such as legislation and case law.

Why Is OSCOLA Referencing Important?

OSCOLA (Oxford Standard for the Citation of Legal Authorities) is one of the most widely used legal referencing styles in UK universities.

Correct OSCOLA referencing helps you:

• Demonstrate academic integrity

• Credit original legal sources

• Avoid plagiarism

• Improve the credibility of your legal arguments

• Meet university assessment requirements

Incorrect citations can result in lost marks even if your legal analysis is strong.

Step 1: Understand the Assignment Question

Before researching, carefully read your assignment brief.

Ask yourself:

• What legal issue must I address?

• Which area of law applies?

• Is this a problem question or an essay?

• Which jurisdiction applies?

• Is OSCOLA referencing required?

• What is the required word count?

• What are the assessment criteria?

Pay close attention to command words.

Understanding these instructions ensures your assignment answers exactly what your lecturer expects.

Step 2: Conduct Legal Research

Strong law assignments rely on authoritative legal sources.

Use trusted legal databases such as:

• Westlaw

• Lexis+

• HeinOnline

• BAILII

• Practical Law

• Google Scholar (Legal)

• Official Government Legislation Websites

Research should include:

• Statutes

• Case law

• Law Commission reports

• Academic journal articles

• Legal textbooks

• Government publications

Avoid relying on blogs, forums, Wikipedia, or unofficial legal summaries.

Step 3: Plan Your Assignment

Create a logical structure before writing.

Example outline:

Introduction

↓

Background to the Legal Issue

↓

Relevant Legislation

↓

Relevant Case Law

↓

Legal Analysis

↓

Application of Law

↓

Critical Evaluation

↓

Conclusion

Planning first improves clarity and logical flow.

Step 4: Write a Strong Introduction

Your introduction should:

• Introduce the legal issue

• Provide relevant background

• Explain why the topic is important

• State the purpose of the assignment

• Outline what will be discussed

Example:

This assignment examines the principles of negligence under English tort law by analysing statutory provisions, leading case law, and academic commentary before evaluating the effectiveness of the current legal framework.

Step 5: Research Primary and Secondary Legal Sources

A strong law assignment balances different legal authorities.

Primary Sources

• Acts of Parliament

• Regulations

• Case Law

• Court Judgments

Secondary Sources

• Legal textbooks

• Journal articles

• Law Commission reports

• Academic commentary

Primary sources generally carry greater legal authority.

Step 6: Apply IRAC or ILAC

Many law schools recommend using structured legal analysis.

IRAC Method

• Issue – Identify the legal issue.

• Rule – Explain the relevant legal rule.

• Application – Apply the law to the facts.

• Conclusion – Reach a reasoned conclusion.

ILAC Method

• Issue

• Law

• Application

• Conclusion

Using these frameworks helps produce clear, logical legal arguments.

Step 7: Use OSCOLA Referencing Correctly

OSCOLA uses footnotes instead of in-text citations.

Examples:

Case

Donoghue v Stevenson [1932] AC 562 (HL).

Legislation

Human Rights Act 1998, s 6.

Book

HLA Hart, The Concept of Law (3rd edn, Oxford University Press 2012).

Journal Article

John Smith, 'Judicial Review and Administrative Law' (2024) 45 Legal Studies 210.

Always check punctuation, italics, and formatting because OSCOLA has strict citation rules.

Step 8: Demonstrate Critical Legal Analysis

High-scoring assignments do more than explain the law.

Critically evaluate:

• Judicial reasoning

• Strengths and weaknesses of legislation

• Conflicting judgments

• Academic opinions

• Policy considerations

• Law reform proposals

Support every argument with legal authority.

Step 9: Proofread Your Assignment

Before submitting:

✔ Check OSCOLA citations

✔ Verify footnotes

✔ Ensure consistent formatting

✔ Check grammar

✔ Review legal terminology

✔ Confirm word count

✔ Proofread carefully

Common Mistakes Students Make

Avoid these common errors:

• Incorrect OSCOLA referencing

• Weak legal analysis

• Describing instead of evaluating

• Missing case law

• Relying only on textbooks

• Ignoring legislation

• Poor assignment structure

• Unsupported legal arguments

• Failing to answer the question

Tips for Achieving High Marks

• Read the assignment brief carefully.

• Use authoritative legal databases.

• Support every argument with legal authority.

• Apply IRAC or ILAC where appropriate.

• Critically analyse rather than describe.

• Use accurate OSCOLA footnotes.

• Proofread every citation before submission.

Final Thoughts

Writing a law assignment using OSCOLA requires careful legal research, critical thinking, and precise referencing. By understanding the assignment brief, using authoritative legal sources, applying structured legal analysis such as IRAC, and following OSCOLA citation rules accurately, you can produce a professional, well-supported assignment that meets university standards.

Focus on building logical legal arguments, supporting every claim with legislation or case law, and maintaining consistent OSCOLA formatting throughout your work. These practices will help you improve both your grades and your legal writing skills.
