OSCOLA is the Oxford University Standard for Citation of Legal Authorities. It is a footnote-based system used by many law schools in the United Kingdom and elsewhere for citing cases, legislation, books, articles and other legal sources.

Do I need a bibliography with OSCOLA?

OSCOLA does not require one, because the footnotes give full details, but many law schools ask for a bibliography. Check your assignment instructions.

What edition of OSCOLA should I use?

The widely used version is the fourth edition. Because publishers and faculties can update guidance, check the Oxford Faculty of Law's OSCOLA page and your own law school's instructions.

Are titles in quotation marks or italics in OSCOLA?

Book titles and case names are italicized. Article, chapter and thesis titles go in single quotation marks. Check the specific source type, as the pattern differs between them.

Do footnotes end with a full stop?

Yes. Every OSCOLA footnote ends with a full stop, even when it is only a citation.

OSCOLA Referencing for Law Students

Law students quickly learn that a legal argument depends on authority, and that citing that authority correctly is part of the argument. OSCOLA, the Oxford University Standard for Citation of Legal Authorities, is the style many UK law schools use. It is built around footnotes, and it has detailed patterns for the sources lawyers use most: cases, legislation, books and articles.

This guide explains the shape of OSCOLA and shows examples, using real legal sources where they are well known and invented ones where they are not. Law schools sometimes apply local variations, so your assignment instructions and the official OSCOLA guide are the final word.

How OSCOLA works

OSCOLA uses footnotes at the bottom of each page, with a superscript number in the text. The footnote gives the full citation the first time a source appears, and a short form after that. Footnotes are numbered in order through the paper.

There are three key features:

Citations live in the footnotes, so the text stays clean.
Every footnote ends with a full stop.
There are specific formats for cases, legislation, books, articles and more.

A bibliography is optional in the standard system, but many law schools require one, usually divided into sections such as cases, legislation and secondary sources.

Footnote numbers in the text

Place the number after punctuation, at the end of the clause or sentence it supports, and use Arabic numerals in order. In OSCOLA, you place the footnote number after the punctuation mark.

The court held that a manufacturer owes a duty of care to the ultimate consumer.¹

Citing cases

UK cases

Format: Case name [Year] Report volume Report abbreviation First page (Court).

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

Case names are italicized, and "v" has no full stop. Square brackets are used where the year is part of the citation, and round brackets where the year is not essential for finding the case. When you refer to a particular page or paragraph, add a pinpoint: Donoghue v Stevenson [1932] AC 562 (HL) 580.

Cases from other jurisdictions

Give the citation in the form used by that jurisdiction, with the court named where necessary, and follow the OSCOLA guidance on foreign material.

Citing legislation

Statutes are cited by title and year, with no comma before the year.

Human Rights Act 1998, s 6.

Use "s" for a section and "ss" for sections, without a full stop. Subsections and paragraphs follow a standard pattern, such as s 6(1)(a). Statutory instruments are cited by name, year and number: Consumer Rights Act 2015 and relevant regulations follow the same logic, with the number given in the form SI 2013/3134.

Citing books

Format: Author, Title (Publisher Year) page.

Hart HLA, The Concept of Law (Oxford University Press 1961) 12.

In footnotes, give the author's name as it appears on the title page. Many guides use the first name or initials followed by the surname in footnotes, and the surname followed by initials in the bibliography. For books with several authors, list them in the order shown, and use "and" between the last two. For an edition: Title (2nd edn, Publisher Year).

Citing journal articles

Format: Author, 'Title of Article' [Year] or (Year) Volume Journal Abbreviation First page, pinpoint.

Smith J, 'Duty of Care in Modern Tort' [2021] CLJ 245, 250.

Article titles go in single quotation marks. Journal names are usually abbreviated according to the OSCOLA guide, and not italicized. Use square brackets when the year identifies the volume, and round brackets with a volume number when it does not.

Citing websites and other sources

Websites are cited with the author, title, the site, the date and the URL, and often an access date.

Law Commission, 'Reform of Contract Law' (Law Commission, 12 March 2024) www.example.org/contract accessed 12 March 2025.

Government reports, command papers, Hansard and EU materials each have their own format in OSCOLA. When you meet a source you cannot match, find the closest example in the official guide, and follow it.

Short forms and cross-references

After the first full citation, use a short form.

Cross-reference to an earlier footnote: Smith (n 4) 252.
Ibid: OSCOLA allows "ibid" for the immediately preceding source: Ibid 253. Use it only when the preceding footnote contains one source.
Short title: For frequently cited cases or statutes, you can define a short title the first time: Donoghue v Stevenson [1932] AC 562 (HL) ('Donoghue').

Cross-references use the footnote number in which the full citation appears, in the form (n 4).

Quotations

Short quotations are placed in single quotation marks inside the text, and quotations within them use double quotation marks. Longer quotations, usually of more than about three lines, are indented without quotation marks. Always include a pinpoint reference in the footnote. In law, accurate quotation matters: do not alter or paraphrase statutory wording where precision is needed.

The bibliography

If your school requires one, organize it into sections.

Cases, in alphabetical order.
Legislation, often divided into primary and secondary.
Books and articles, alphabetical by author's surname, with initials after the surname and no punctuation in the name.

In the bibliography, do not give pinpoint pages for books. For articles, give the page range. Check your assignment for the sections you need.

Formatting a law essay

Many law schools prefer a clear structure of introduction, issues, analysis and conclusion, with footnotes in a smaller font than the main text, such as 10 point, single spaced. Numbering of footnotes is continuous. Always check the word limit rules for footnotes, because some institutions count them and others do not.

Citing secondary legal sources and materials

Law essays also draw on sources beyond cases and statutes.

Commentary and textbooks: cite as books, with the edition and the page.
Command papers and official reports: give the author or body, the title, the series and number, and the year.
Parliamentary materials (Hansard): cite the date, the volume and the column.
EU legislation and cases: use the official journal reference or the case number, following the OSCOLA examples for EU materials.
International materials: cite treaties and international cases in the form given in the OSCOLA guide.
Online-only sources: give the author, title, site, date and URL, and an access date.

If you cannot find the exact pattern, find the nearest example in the official guide, and apply it consistently. Law markers care less about which example you pick than about whether your citations are accurate, complete and consistent.

A short worked footnote sequence

Here is how a short run of footnotes might look in a paper on negligence.

Donoghue v Stevenson [1932] AC 562 (HL) 580.

Hart HLA, The Concept of Law (Oxford University Press 1961) 12.

Human Rights Act 1998, s 6.

Donoghue (n 1) 599.

Ibid.

Footnote 4 uses the short title defined earlier together with the cross-reference. Footnote 5 uses ibid because the preceding footnote contains only one source. Each ends with a full stop.

Common OSCOLA mistakes

Missing full stops at the end of footnotes.
Italicizing the wrong things, such as article titles.
Wrong brackets for the year in case and article citations.
Missing pinpoint references.
Using "ibid" incorrectly when the preceding footnote has more than one source.
Inconsistent abbreviations for reports and journals.
Putting the footnote number before punctuation.
Forgetting to cite primary authority for a legal proposition.

A quick checklist

Are footnote numbers after punctuation, in order?
Does every footnote end with a full stop?
Are cases italicized and legislation formatted correctly?
Do I give pinpoints for quotations and specific propositions?
Have I used short forms and (n x) cross-references correctly?
Do I have a bibliography if the assignment requires one?
Have I followed my law school's instructions?

Final thoughts

OSCOLA is demanding because law demands precision, but its patterns are consistent. Learn the formats for cases and legislation first, since they appear in almost every law essay, keep a template for footnotes and check each citation against the official guide as you write. Then your references support your argument instead of distracting from it.
