Definition
A doctrine of Scots law. Vitious intromission is the unauthorized taking or intermeddling with the movable estate of a deceased person without legal authority to do so. A person who vitiously intromits with a decedent's movable goods — that is, handles, removes, or deals with them without being a confirmed executor or otherwise legally authorized — becomes liable for the whole of the deceased's debts, not merely the value of what was taken.
The doctrine operates as a penalty rather than as a property rule. Its severity lies in the consequence: the intromitter cannot limit liability to the assets actually touched. By handling the estate without authority, the intromitter assumes universal liability as if they were the confirmed executor of the estate.

Common Confusion
The term is sometimes loosely compared to the common law concept of executor de son tort — a person who intermeddling with a decedent's estate without lawful authority and thereby becomes liable. The two doctrines share a structural similarity: unauthorized dealing with estate assets triggers personal liability. However, vitious intromission is a specifically Scots law concept with its own procedural history and consequences rooted in civilian legal tradition. Researchers should not treat executor de son tort authorities as controlling or directly translatable when working with Scottish sources.

Why It Matters in Research
This is a term of pure Scots law and will appear almost exclusively in Scottish legal sources, older British treatises, and comparative law discussions. Researchers encountering it in historical materials should be aware of several points:
The doctrine was harsh in its original form. Early Scots law imposed unlimited personal liability for the entire debt burden of the deceased on any unauthorized intromitter, regardless of whether the intromission was in good faith or of minimal value. Later Scots law softened this rule through equitable mitigation, and Erskine's Principles (the source cited in all major historical dictionaries) reflects the doctrine in its developed but still stringent form.
The term rarely appears in English common law materials. When it surfaces in American legal dictionaries — as it does in Black's and Bouvier's — it is purely by inheritance from English legal lexicography, not because the doctrine operated in American jurisdictions. A researcher finding this term in an American source should treat it as definitional reference, not as authority for a doctrine with domestic application.
The word "vitious" is an older spelling of "vicious" and carries here the Scots legal sense of "defective" or "unauthorized" rather than the moral sense of wickedness. This orthographic distinction matters when searching historical indexes, catalogues, and digitized sources, which may not resolve variant spellings consistently.
Burrill and Black both cite Erskine's Principles (book 3, title 9, section 25) and Kames' Principles of Equity as the underlying authorities. Researchers wanting depth on this doctrine should go directly to those sources rather than relying on the compressed dictionary treatment.

Historical Dictionary Support
The four source dictionaries are in close agreement. All four define vitious intromission as unwarrantable intermeddling with the movable estate of a deceased person without the order of law. Black's (1st Ed.) and Burrill add the crucial consequential element: that such irregular intermeddling subjects the party to the whole debts of the deceased. Bouvier's entry is the most abbreviated, omitting this liability consequence entirely — a significant gap for any researcher who needs to understand why the doctrine mattered.
All sources trace the authority to Erskine. The citation consistency across Black's, Burrill, and the Erskine reference is reliable. Kames' Equity is cited by Black's and Burrill as secondary authority for the liability rule.
None of the dictionary sources discuss the equitable softening of the doctrine over time, nor the procedural mechanisms by which Scots courts addressed disputed intromissions. For that history, primary Scottish institutional writers — Erskine, Stair, and Bell — are the necessary sources.

Jurisdictional Note
Vitious intromission is a doctrine of Scots law with no operative application in English common law or American jurisdictions. It may appear in English and American legal dictionaries as a comparative or definitional entry, but this reflects the encyclopedic tradition of those dictionaries, not any reception of the doctrine into those legal systems.
