Definition
Temporary estate duty is a form of death duty — a tax imposed on the transfer of property at death — assessed specifically in connection with limited or temporary interests in property, such as life estates, annuities, or other interests that do not pass outright and permanently to a beneficiary but instead vest for a defined or contingent period. The duty was designed to capture revenue from wealth transfers where the interest being passed is less than a full fee simple, requiring valuation methods that account for the time-limited nature of the interest.
As a species of death duty, temporary estate duty operated alongside (and was often distinguished from) estate duty proper, which applied to absolute transfers of the full beneficial interest in property. Temporary estate duty addressed the gap: where a deceased person held or settled an interest that would expire or revert, the tax authority needed a mechanism to assess and collect duty proportionate to the value of that temporal interest rather than the full capital value of the underlying property.

Common Confusion
Temporary estate duty is easily conflated with estate duty generally, and researchers sometimes treat the two as interchangeable. They are not. Estate duty (in the British and Commonwealth tradition) was the general charge on property passing at death. Temporary estate duty was a narrower, technically distinct charge calibrated to interests of limited duration — life interests being the paradigm case. Conflating the two leads to misreading valuation schedules, actuarial tables, and exemption thresholds in historical tax documents, since each duty operated under different computational rules. Researchers should also distinguish both from succession duty and legacy duty, which were separate charges on the recipient rather than the estate.

Why It Matters in Research
This term appears in historical British and Commonwealth legal materials, primarily from the late nineteenth and early twentieth centuries, when death duties were reformed and stratified into overlapping charges. The Finance Act 1894 (U.K.) consolidated and restructured estate duty, and temporary estate duty must be understood against that legislative backdrop.
Researchers working in Law Mind's property law corpus will encounter this term most often in materials dealing with settled estates, trusts for life, and testamentary life interests — the same territory covered in the Life Estate entry of the Property Law Encyclopedia. When reviewing historical deeds, settlement documents, or estate accounts, the presence of temporary estate duty notations signals that the property in question was subject to a life interest or similar limited grant rather than an outright bequest.
Three practical traps for corpus researchers:
First, valuation. Temporary estate duty was computed using actuarial life tables to determine the present value of a time-limited interest. Historical documents may reference tables, rates, or schedules that were revised multiple times between 1894 and the eventual abolition of estate duty in the U.K. (replaced by capital transfer tax in 1975, itself later replaced by inheritance tax in 1986). A rate or table reference in a 1910 document will not match one from 1930.
Second, terminology instability. Older sources use "estate duty," "temporary estate duty," "succession duty," and "legacy duty" inconsistently, sometimes using the general term when the specific charge is intended. Bouvier's directs the reader to the DEATH DUTIES entry rather than defining the term independently — a signal that the historical dictionaries treat this as a term of art within a larger system rather than a freestanding concept.
Third, jurisdictional carry-over. Commonwealth jurisdictions — particularly Australia, Canada, and New Zealand — adopted variants of British death duty law with local modifications. The label "temporary estate duty" may appear in colonial or dominion materials with rules that diverge from their English source. Researchers should not assume uniform treatment across common law jurisdictions.

Historical Dictionary Support
Bouvier's Law Dictionary does not define temporary estate duty as a standalone entry, redirecting instead to DEATH DUTIES. This is itself informative: Bouvier's treats the term as a subcategory of a broader fiscal concept rather than an independent legal institution. This is consistent with how the term functioned in practice — it was a classification within a death duties regime, not a separate tax with its own legislative framework.
The absence of a full definition in Bouvier's reflects the primarily American orientation of that dictionary. Temporary estate duty was a creature of British and Commonwealth fiscal law; American inheritance and estate taxation developed along different structural lines, without the specific life-interest duty mechanism that gave rise to this term. Researchers relying solely on American legal dictionaries will find little guidance and should consult British sources — including Stroud's Judicial Dictionary and Halsbury's Laws of England — for meaningful doctrinal treatment.
Historical legal dictionaries broadly agree that death duties in the British tradition comprised multiple overlapping charges, each with distinct bases of assessment. Where they diverge is in the specificity with which they treat each subcategory. Bouvier's compression of the term into a cross-reference accurately reflects American practice but obscures the technical precision the term carried in British usage.

Jurisdictional Note
Temporary estate duty is a term of British and Commonwealth law with no direct American equivalent. U.S. federal estate tax, established in its modern form by the Revenue Act of 1916, applied to the full taxable estate without a parallel mechanism specifically targeting time-limited interests in the same structural way. Researchers encountering this term in American documents are likely reading materials that reference English law, trust instruments drafted by English practitioners, or cross-border estate administration.
