Definition
An interlocutory decree is a court order or judgment issued during the course of a proceeding that does not finally resolve the case. It addresses a specific issue, directs further proceedings, or establishes interim rights and obligations, but leaves the ultimate disposition of the matter to a later, final decree.
The term originates in equity practice, where the distinction between interlocutory and final decrees governed whether a party could immediately appeal and what binding effect an order carried. Though modern courts have largely merged law and equity, the concept persists wherever courts must act at an intermediate stage — resolving a question of law or fact, ordering a reference or accounting, or imposing temporary relief — without closing the case.
Two functional uses dominate:
1. Procedural interlocutory decree: An order directing further steps before final judgment — for example, ordering a master to take an accounting, directing discovery, or bifurcating liability and damages for separate determination.
2. Substantive interlocutory decree: An order that resolves a discrete legal right or status provisionally but leaves related issues open — most prominently, an interlocutory decree of divorce, which adjudicates the dissolution of the marriage but reserves questions of property, support, or custody for later proceedings.

Common Confusion
INTERLOCUTORY DECREE vs. FINAL DECREE: The distinction carries significant consequences for appellate jurisdiction. A final decree resolves all issues as to all parties and is generally the only judgment immediately appealable as of right. An interlocutory decree, being provisional, is ordinarily not immediately appealable unless it falls within a statutory exception or the court certifies it for interlocutory appeal. Researchers should not assume that a court order labeled "decree" is final; the functional test is whether anything material remains to be decided.
INTERLOCUTORY DECREE vs. PRELIMINARY INJUNCTION: Both are interim orders, but a preliminary injunction preserves the status quo pending final resolution and carries its own procedural standards. An interlocutory decree in the historical equity sense is a broader category — it may direct proceedings, settle questions of law, or grant interim relief, without necessarily imposing the injunctive framework. Modern usage sometimes collapses the distinction carelessly.

Why It Matters in Research
The term has two distinct lives in the corpus, and conflating them produces research errors.
First, in historical equity sources, "interlocutory decree" is procedural vocabulary specific to Chancery practice. The category governed when a court of equity could act without fully hearing the cause and what further proceedings — references to a master, inquiries, accountings — were required before a final decree could issue. Sources predating the merger of law and equity under the Federal Rules (1938) use the term in this narrow technical sense. Researchers reading 19th-century cases or treatises should understand that "interlocutory decree" in that context does not simply mean "any non-final order."
Second, in family law, the interlocutory decree of divorce is a distinct and still-operative concept in several states. It imposes a waiting period between the judicial determination that grounds for divorce exist and the entry of a final divorce decree. This waiting period has practical consequences: neither party is free to remarry, property rights may remain unsettled, and the decree is modifiable. This usage is jurisdictionally specific and has no parallel in general civil practice.
For appellate research, the interlocutory/final distinction governs jurisdiction. Researchers working with pre-1948 federal materials should note that appellate jurisdiction over interlocutory orders was more limited than today; the statutory expansion of interlocutory appeal rights under 28 U.S.C. § 1292 changed the landscape materially. State court equivalents vary widely.
Historical sources in the Law Mind corpus — particularly practice treatises from the mid-19th century — use "interlocutory decree" in the Chancery sense almost exclusively. Modern family law materials use it almost exclusively for the divorce context. The same phrase, indexed the same way, can mean two different things depending on the source date and subject matter.

Historical Dictionary Support
Black's and Burrill's converge closely, and both draw on the same sources: Blackstone's Commentaries (3 Bl. Com. 452) and Barbour's Chancery Practice (1 Barbour's Ch. Pr. 326–327). The definition each offers is functionally identical — a preliminary decree directing further proceedings before a final decree can issue.
Neither dictionary addresses the family law usage, which developed as a distinct application later in American practice. Neither engages with the appellate jurisdiction consequences that became the term's primary significance in modern federal practice. Researchers relying solely on these historical definitions will understand the equity procedure origins of the term but will miss its contemporary significance in two important areas: interlocutory appellate practice under statutory frameworks, and the interlocutory divorce decree as a substantive family law instrument.
Burrill's citation to Blackstone is useful for tracing the Chancery origins. The Barbour citation in both dictionaries points to one of the standard 19th-century American equity practice treatises; researchers who locate that source will find more granular procedural detail about when and how interlocutory decrees were issued in American equity courts.

Jurisdictional Note
Several states — historically including California — used an interlocutory decree of divorce as a mandatory procedural step, imposing a waiting period (often six months to a year) before a final divorce decree could enter. California abolished the interlocutory divorce decree in 1970, replacing it with a waiting period running from service of process. Researchers working with California family law materials before 1970 will encounter the interlocutory decree as an operative legal document with specific consequences. Other states retain analogous mechanisms under varying names.
