Definition
A tax imposed on the total value of property transferred upon a person's death. Estate duty is levied on the principal value of all property — real and personal, settled and unsettled — that passes from the deceased to beneficiaries or successors. It is assessed against the estate as a whole, rather than against individual inheritances received by heirs.
In its classic English form, estate duty applied to:
1. All real and personal property wherever situated, if the deceased died domiciled in Britain.
2. All real property located within Britain, regardless of the deceased's domicile.
3. Property that "passes on death," including certain gifts and transfers made within a defined period before death, deemed to be part of the dutiable estate.
Estate duty is a predecessor concept to modern inheritance and estate taxes. The term remains historically significant but is largely obsolete as a live statutory label in most jurisdictions, having been replaced by successor taxes under different names.

Common Confusion
ESTATE DUTY vs. INHERITANCE TAX vs. ESTATE TAX
These three terms are frequently conflated but reflect different tax architectures. Estate duty and estate tax are levied on the estate itself before distribution — the obligation falls on the estate or its executors. Inheritance tax, by contrast, is typically levied on the individual beneficiary's receipt of property, and may vary depending on the relationship between the deceased and the recipient. In the United Kingdom, estate duty was formally replaced by Capital Transfer Tax in 1975, which was itself replaced by Inheritance Tax in 1986 — so a researcher encountering "estate duty" in a British source is almost certainly working with pre-1975 material. In the United States, the term "estate tax" is standard; "estate duty" rarely appears in American legal sources.

Why It Matters in Research
Researchers working in British legal materials will encounter estate duty throughout sources from 1894 to 1975. The Finance Act 1894 is the foundational statute and is the law Bouvier's entry describes. Any case law, conveyancing document, trust instrument, or estate administration record from this period in England and Wales may reference estate duty obligations, exemptions, or duty-avoidance arrangements.
Several traps await the researcher in historical sources:
First, the scope of "property passing on death" under the 1894 Act was litigated extensively. The phrase was construed broadly to capture gifts with reservation, certain trust arrangements, and joint property — meaning that documents nominally unrelated to estates (gift deeds, trust settlements, joint tenancy instruments) may carry estate duty implications.
Second, rates and exemptions changed substantially over the 80-year life of estate duty. Sources citing estate duty figures must be read with attention to the applicable year; wartime and post-war amendments dramatically altered both rates and the definition of dutiable property.
Third, the distinction between "settled" and "unsettled" property matters for how duty was calculated and who was primarily liable to pay it. Settled property — property held under a trust or settlement — was treated differently from outright ownership. Researchers working with trust instruments from this era should expect to find provisions specifically addressing estate duty liability between life tenants and remaindermen.
Fourth, domicile is central to jurisdiction. Estate duty applied universally to British-domiciled decedents regardless of where property was located, but applied to foreign-domiciled decedents only as to British situs property. This makes domicile determinations in historical probate litigation legally consequential, not merely biographical.
For researchers in Commonwealth jurisdictions — Australia, Canada, New Zealand, South Africa — parallel estate duty regimes operated under local legislation modeled on the British framework. Sources from these jurisdictions will use the term "estate duty" but may diverge significantly in structure, rates, and exemptions.

Historical Dictionary Support
Bouvier's entry describes estate duty precisely as a product of the Finance Act 1894, section 1 — correctly identifying both the statutory source and the operative date of August 1, 1894. The entry captures the dual scope: domicile-based universal liability for British subjects and situs-based liability for foreign domiciliaries as to British real property.
Bouvier's entry, as reproduced here, is truncated; the full entry in complete editions of Bouvier's addresses the rates, the treatment of settled property, and the class of exemptions (including certain charitable and small estate exemptions). Researchers should consult complete editions rather than abridged versions when using Bouvier's for estate duty analysis, as the exemption structure is material to any practical question about historical estate administration.
Bouvier's treatment reflects the law as it stood near the time of the dictionary's relevant edition. It does not address the subsequent statutory amendments that layered additional duties onto the 1894 framework — notably the amendments introduced through successive Finance Acts in the early twentieth century, which increased rates substantially and narrowed exemptions. Other historical legal dictionaries, including Stroud's Judicial Dictionary, address the extensive case law that construed the phrase "passes on death," which is the interpretive center of the statute and the source of most historical litigation.

Jurisdictional Note
Estate duty as a term of art is primarily British and Commonwealth in origin. The United States adopted a federal estate tax under separate statutory authority and has never widely used the term "estate duty." Researchers must not assume that British estate duty doctrine, rates, or exemptions translate to American estate tax law. In the United Kingdom, estate duty was abolished and replaced by Capital Transfer Tax (Finance Act 1975), later rebranded as Inheritance Tax (Inheritance Tax Act 1984). Some Commonwealth nations retained the label "estate duty" longer than the UK; others have since repealed estate duty entirely.

Encyclopedia Cross-Reference
No Law Mind Encyclopedia entry directly addresses estate duty as a tax concept. For background on property interests that frequently intersected with estate duty liability, see:
