Definition
The Royal Courts of Justice (commonly abbreviated RCJ) is the principal court complex in England and Wales, located on the Strand in London, housing the High Court of Justice and the Court of Appeal. As an institutional term, it refers both to the physical building and, historically, to the superior courts of common law that were consolidated and relocated there following the Judicature Acts of 1873–1875.
Before consolidation, the "Royal Courts of Justice" was used more loosely to describe the collection of superior common law courts sitting at Westminster Hall — including the Court of King's (or Queen's) Bench, the Court of Common Pleas, and the Court of Exchequer — each of which derived its jurisdiction from the Crown. The Judicature Acts abolished these separate courts and unified them into a single Supreme Court of Judicature, comprising the High Court and the Court of Appeal. The new building on the Strand, opened in 1882, became and remains the seat of those courts.
In modern usage, "Royal Courts of Justice" refers specifically to the Strand building and the courts sitting within it, principally the High Court of Justice (organized into the King's/Queen's Bench Division, Chancery Division, and Family Division) and the Court of Appeal.

Common Confusion
The Royal Courts of Justice should not be confused with the UK Supreme Court, which since 2009 has occupied Middlesex Guildhall in Parliament Square and serves as the final court of appeal for civil matters across the United Kingdom and for criminal matters in England, Wales, and Northern Ireland. Before 2009, the Appellate Committee of the House of Lords performed that function, and the terminology in older sources can obscure this distinction. Researchers should also note that the Central Criminal Court (the Old Bailey) is entirely separate and handles serious criminal matters for Greater London — it is not part of the Royal Courts of Justice.
Additionally, the older pre-Judicature Acts usage of "Royal Courts" or "King's Courts" as a generic phrase for Crown-derived superior courts appears frequently in historical legal literature and should be distinguished from the specific institutional and architectural meaning that crystallized after 1882.

Why It Matters in Research
The central research trap with this term is chronological. Sources written before 1875 use "Royal Courts of Justice" or "the Royal Courts" to describe the Westminster Hall ensemble — King's Bench, Common Pleas, Exchequer — as a collective concept rooted in royal authority, not a specific institution. Sources written after 1882 use the same phrase as a proper noun for a specific building and its consolidated courts. A researcher reading across the divide without awareness of this shift may misattribute procedural rules, jurisdictional statements, or descriptions of court practice to the wrong institutional framework.
The Judicature Acts are the pivot point for nearly all English procedural law research in the Law Mind corpus. Cases and treatises from before 1875 operate under separate court rules for each division; the fusion of law and equity accomplished by the Acts changes the procedural landscape fundamentally. Any English authority on equitable remedies, injunctions, or pleading practice must be read with its pre- or post-Judicature Act status clearly identified.
Jurisdictional coverage also matters. The Royal Courts of Justice sit in England and Wales. Scottish law (which has its own Court of Session) and Northern Irish law (Court of Judicature of Northern Ireland) are separate. Historical sources sometimes speak of "English courts" and "British courts" interchangeably in ways that can mislead researchers into assuming Scottish precedent when only English authority was intended, or vice versa.
For American researchers using English authorities, the relevance of RCJ decisions depends heavily on the era. Pre-Independence English common law decisions carry potential persuasive or foundational authority in American courts; post-Independence decisions are persuasive only and vary in reception by state. The distinction between which English court issued a decision — King's Bench versus Chancery versus Exchequer — matters for understanding whether it applied at common law or in equity, a distinction that remains live in American jurisdictions that have not fully merged law and equity.

Historical Dictionary Support
Rapalje & Lawrence define the Royal Courts of Justice as the court building opened in London in 1882 to consolidate the superior courts established under the Judicature Acts of 1873 and 1875. Their entry situates the term squarely in the post-consolidation sense — the specific institutional building — and does not treat the pre-Judicature Acts usage at length. This reflects the dictionary's primary orientation toward American practitioners working with English authority in the late nineteenth century, who would have encountered the post-consolidation courts as the operative framework.
What Rapalje & Lawrence do not address is the older sense of "Royal Courts" as a descriptor for Crown-derived superior jurisdiction, which appears extensively in Blackstone's Commentaries, early English treatises, and American authorities importing English common law doctrine. Researchers relying solely on Rapalje & Lawrence for this term will get the post-1882 institutional meaning accurately but will miss the conceptual genealogy that connects the modern RCJ to the medieval and early modern development of royal judicial authority.

Jurisdictional Note
The Royal Courts of Justice is an England-and-Wales institution. Scottish procedure runs through the Court of Session (civil) and High Court of Justiciary (criminal) in Edinburgh. For American legal history purposes, the relevant predecessor courts are those that predated the Judicature Acts — particularly King's Bench and Common Pleas — whose decisions form part of the common law inheritance received by American states.
