OSCOLA referencing is the footnote-based citation system used by UK law schools. Instead of in-text brackets, you place a superscript number after the relevant sentence and give the full source in a footnote at the bottom of the page, then list every source again in a bibliography at the end. It is the essential standard for law essays, dissertations and exams across the UK, and getting it right is one of the easiest ways to protect your marks.
Key takeaways
- OSCOLA stands for the Oxford University Standard for the Citation of Legal Authorities.
- It uses numbered footnotes, not in-text citations like Harvard or APA.
- Cite in this order of authority: cases, then legislation, then secondary sources.
- OSCOLA uses minimal punctuation, but every footnote ends with a full stop.
- Finish with a bibliography grouped into Cases, Legislation and Secondary Sources.
What is OSCOLA referencing?
OSCOLA referencing is the citation style created by the University of Oxford for legal writing. It tells you exactly how to cite cases, statutes, journal articles, books and online sources so that any reader can trace your authority. Most UK law degrees require OSCOLA referencing for coursework, dissertations and examinations, which is why mastering it early saves you marks throughout your degree.
How does OSCOLA referencing work?
OSCOLA referencing works in two layers. First, a superscript footnote marker is placed in your text, normally after the closing punctuation. Second, the matching footnote at the foot of the page gives the full citation. When you cite the same source again, you use a shortened form such as ibid for the source in the footnote immediately above, or the author surname with the original footnote number, for example Craig (n 4).
How do you reference a case in OSCOLA?
Give the case name in italics, then the year, the court and the report. Use the neutral citation first where one exists:
- Neutral citation: R (Miller) v The Prime Minister [2019] UKSC 41.
- Law report: Donoghue v Stevenson [1932] AC 562 (HL).
Pinpoint a specific paragraph or page after the citation, for example [2019] UKSC 41 [55] for paragraph 55.
How do you cite legislation in OSCOLA?
Cite UK Acts by their short title and year, with no comma before the year, and pinpoint the section where needed:
- Human Rights Act 1998, s 6.
- Senior Courts Act 1981, s 33(2).
For statutory instruments, give the name, year and SI number, for example The Equality Act 2010 (Commencement No 4) Order 2010, SI 2010/2317.
How do you reference journal articles, books and websites?
- Journal article: Paul Craig, ‘Theory and Values in Public Law: A Response’ [2005] PL 440.
- Book: Gary Slapper and David Kelly, The English Legal System (16th edn, Routledge 2015) 45.
- Website: Law Commission, ‘About Us’ (Law Commission) <https://www.lawcom.gov.uk> accessed 18 June 2026.
OSCOLA footnotes vs bibliography: what is the difference?
Footnotes and the bibliography do different jobs. A footnote supports a single point on a single page and is numbered. The bibliography is a complete alphabetical list of everything you used, with no footnote numbers, placed at the very end. In a footnote the author’s first name comes first; in the bibliography the surname comes first.
How do you handle repeat citations (ibid and cross-references)?
- ibid – use when the source is identical to the one in the footnote directly above. Add a pinpoint if the page differs, e.g. ibid 47.
- (n x) – use to point back to an earlier footnote, e.g. Craig (n 4) 442.
How do you format an OSCOLA bibliography?
List sources, without footnote numbers, under three headings in this order: Table of Cases, Table of Legislation and Secondary Sources. Order cases and legislation alphabetically, and order secondary sources alphabetically by author surname.

OSCOLA referencing in dissertations and theses
In a law dissertation, apply OSCOLA referencing consistently from the first chapter and keep a running bibliography as you write. Examiners look closely at citation accuracy, so a final OSCOLA check before submission is worthwhile. For wider study support, see our guides on how to write an essay and how to write coursework. The full official rules are published by the University of Oxford Faculty of Law.
Common OSCOLA referencing mistakes to avoid
- Using in-text brackets instead of footnotes.
- Adding a comma before the year in a case or statute.
- Forgetting the full stop at the end of a footnote.
- Mixing OSCOLA with Harvard or APA in the same document.
- Leaving footnote numbers in the bibliography.

Frequently asked questions about OSCOLA referencing
Does OSCOLA use a reference list or a bibliography?
OSCOLA uses a bibliography, not a reference list. It appears at the end of the document and groups every source under Cases, Legislation and Secondary Sources.
Is OSCOLA referencing the same as footnotes?
OSCOLA is delivered through footnotes, but it is a complete citation style with its own rules for punctuation, order of authority and bibliography formatting, not simply the act of adding footnotes.
Is OSCOLA referencing used outside UK law programmes?
OSCOLA referencing is designed for UK legal writing and is also used by some Commonwealth and international law schools, but most non-law subjects use Harvard, APA or MLA instead.
Is OSCOLA referencing hard to learn?
No. OSCOLA referencing is simple once you learn the order of authority and the punctuation rules. Using the examples above as templates makes it easy to reference consistently.
OSCOLA Footnote Referencing: Practical Examples
OSCOLA uses a footnote citation system in which references appear at the bottom of the page rather than in the body of the text. When you cite a source for the first time, you provide a full citation in the footnote. On subsequent citations of the same source, you use a shortened form. Understanding this two-level system — full first citation, abbreviated subsequent citations — is fundamental to using OSCOLA correctly.
For a case, the full citation format is: Case Name [Year] Court Abbreviation Report Volume Page. For example: Donoghue v Stevenson [1932] AC 562. Note that case names are italicised in OSCOLA. For subsequent citations of the same case, you may simply use the case name in italics: Donoghue v Stevenson. For statutes, cite the full title followed by the year: Human Rights Act 1998. Statutes are not italicised and do not require a footnote unless you are citing a specific section.
For journal articles, the full OSCOLA citation format is: Author, ‘Title of Article’ (Year) Volume Number(Issue Number) Journal Name First Page. For example: Andrew Burrows, ‘The Relationship Between Common Law and Statute in the Law of Obligations’ (2012) 128 LQR 232. Note that article titles are in single quotation marks, not italicised, while journal names use the standard legal abbreviation. For books, the format is: Author, Title of Book (edition, Publisher Year) page number. Book titles are italicised in OSCOLA.
Common OSCOLA Mistakes and How to Avoid Them
Several errors appear consistently in OSCOLA-referenced work submitted by law students at UK universities. The most common is inconsistent use of pinpoint citations — references to the specific page or paragraph number within a source. OSCOLA requires a pinpoint citation whenever you are referring to a particular passage rather than a source as a whole. For cases, this means citing the specific page number where the relevant passage appears: Caparo Industries plc v Dickman [1990] 2 AC 605, 617. Omitting pinpoint citations is a frequent error that suggests imprecision in legal analysis.
A second common error is using ibid incorrectly. OSCOLA permits the use of ‘ibid’ to indicate that a footnote refers to the same source as the immediately preceding footnote. Ibid can be used with or without a different page number: ‘ibid’ alone means the same source and same page; ‘ibid 45’ means the same source at page 45. However, ibid can only be used when the preceding footnote refers to a single source. If the preceding footnote contains multiple citations, ibid cannot be used as it would be ambiguous which source is intended.
Students also frequently make errors in citing secondary sources such as textbooks and journal articles alongside primary sources. In legal writing, primary sources — cases, statutes, treaties — carry the greatest authority, and secondary sources are used to contextualise, explain, or critically analyse the primary law. Your footnotes should reflect this hierarchy: primary sources are cited to support your legal propositions directly, while secondary sources are cited to acknowledge whose analysis you are drawing on. Ensure that you are never substituting secondary commentary for your own engagement with the primary sources — OSCOLA formatting is only one part of strong legal writing; the quality of your legal analysis matters equally.
