Definition
A judicial factor is a court-appointed administrator or manager given legal authority over property or an estate that, for some reason, cannot be managed by its owner or by an ordinary private arrangement. The role is primarily a creature of Scots law, where the Court of Session (and, in certain matters, the sheriff court) appoints an individual — the judicial factor — to take custody of and administer property held in custodia legis: literally, in the keeping of the law.
The judicial factor acts as an officer of the court rather than as an agent of any party. The appointment arises when no one with legal title or capacity is presently able to manage the property, or when administration by a private party would be inappropriate or legally insufficient. Once appointed, the judicial factor must find caution (security), inventory the estate, and report to the Accountant of Court, who supervises the administration on behalf of the court.
Common occasions for appointment include:
- The estate of a person who has died without leaving a will and where no executor has been confirmed (executor-dative proceedings stall or fail);
- The estate of a person under legal incapacity where no guardian or curator exists;
- Dissolved or insolvent partnerships where assets must be protected pending distribution;
- Trust estates where trustee failure, vacancy, or dispute prevents ongoing administration.

Common Confusion
JUDICIAL FACTOR vs. EXECUTOR / TRUSTEE: Although a judicial factor may administer the same kinds of property as an executor or trustee, the judicial factor derives authority entirely from the court, not from a will, trust deed, or private nomination. An executor manages a deceased's estate under testamentary authority or appointment by the court in the executor-dative process; a trustee acts under a trust deed. The judicial factor is distinguishable by the court's direct and continuing supervision of every significant act of administration.
JUDICIAL FACTOR vs. CURATOR BONIS: These roles were historically distinct in Scots law — the curator bonis administered the estate of a living incapax, while the judicial factor covered a broader range of property situations — though both were supervised by the Accountant of Court. Modern Scots law (Adults with Incapacity (Scotland) Act 2000) largely replaced the curator bonis with the financial guardian, but judicial factors remain in use for non-personal-incapacity situations. Researchers reading pre-2000 Scots sources will encounter both terms in roles that modern law now handles differently.

Why It Matters in Research
The judicial factor is a distinctly Scottish legal institution. Researchers working in English, Irish, or American sources will not find the term as an operative concept in those jurisdictions' domestic law, though comparative law texts and 19th-century treatises may reference it when surveying civil law-influenced systems.
In historical Scots law research, the term appears in Session Papers, Accountant of Court records, and Court of Session interlocutors. Bouvier's treatment is brief and treats this as a foreign-law entry, which reflects the term's near-invisibility in American legal literature. Researchers using American legal dictionaries as a first stop should be alert to this — Bouvier points toward Erskine's Institutes but provides no operational detail.
The supervision mechanism — the Accountant of Court — is a consistent thread across all historical periods and is worth tracing separately when researching any judicial factor appointment. The Accountant of Court's records can provide documentary evidence of estate composition, interim accounts, and final discharge that would not appear in court opinions alone.
For researchers working on Scots private law after 2000, note that Adults with Incapacity (Scotland) Act 2000 restructured the personal incapacity side of the judicial factor's traditional work. References to judicial factors in modern Scots legal texts will generally concern trust and partnership estate administration, not personal incapacity management.
Researchers should also be careful with the word "factor" standing alone in Scottish legal and estate management sources. In that context, "factor" frequently means a land agent or estate manager — a private, non-court-appointed role. The modifier "judicial" is doing critical work.

Historical Dictionary Support
Bouvier's Law Dictionary identifies the judicial factor as a figure of Scots law: "an administrator or steward appointed by the court of session for the management of an estate which for any reason is in custodia legis," citing Erskine's Principles (Inst. 1.7, Pr. 253). This is accurate and serviceable but thin — Bouvier treats the term as a foreign-law curiosity rather than engaging with the mechanics of the role.
Erskine's Institutes and Bell's Principles of the Law of Scotland provide substantially more texture, describing the conditions of appointment, the requirement for caution, and the supervisory structure. Later Scots law dictionaries (Trayner's Latin Maxims, Bell's Dictionary and Digest) flesh out the jurisdictional and procedural framework that Bouvier omits.
No meaningful divergence exists among historical sources on the basic character of the role — it is uniformly described as court-derived, supervisory in nature, and tied to property that cannot otherwise be managed. What historical dictionaries miss almost entirely is the Accountant of Court's centrality to ongoing administration, which becomes more apparent in procedural texts and practice guides than in general legal dictionaries.

Jurisdictional Note
The judicial factor is a term of Scots law with no direct equivalent in English, Welsh, or American law. English law achieves analogous results through court-appointed receivers, administrators under insolvency legislation, or the Court of Protection's property and affairs deputies. Researchers working across jurisdictions should treat these as functional analogues, not equivalents, and should not assume that rules governing one map onto the other.
