Definition
A special power to dispose of an estate is a limited authority granted to a person — the donee — to direct the transfer or distribution of property belonging to another (the donor), but only among a defined and restricted class of potential recipients. Unlike a general power, which permits the donee to appoint the property to anyone including themselves, a special power constrains both the manner and the beneficiaries of any disposition. The donee cannot appoint outside the designated class, and typically cannot appoint to themselves or their estate.
The "estate" in this context refers to the property subject to the power — real or personal — not necessarily the totality of a decedent's holdings. The power may be exercised by deed during life or by will at death, depending on how the creating instrument defines its scope.
In practice, this construct appears most frequently in:
(1) Trust instruments, where a settlor grants a beneficiary the power to direct distribution of trust assets among that beneficiary's descendants or a named group;
(2) Wills, where a testator grants a surviving spouse or other legatee the ability to divide or reallocate specific property among a class of family members;
(3) Deeds and settlements, particularly in older conveyancing practice, where a life tenant was empowered to appoint remainder interests among children or issue.
The distinguishing feature is restriction. The power is "special" precisely because it cannot be turned to the donee's own benefit and cannot reach persons outside the designated class.

Common Confusion
SPECIAL POWER vs. GENERAL POWER TO APPOINT: These are the two poles of power-of-appointment doctrine, and conflation is common. A general power permits appointment to the donee, the donee's estate, the donee's creditors, or the creditors of the donee's estate — making the property functionally the donee's own for many tax and creditor-reach purposes. A special (or limited) power does not. The tax consequences differ substantially: property subject to a general power is typically included in the donee's gross estate for federal estate tax purposes; property subject to a special power generally is not. Historical sources, including older dictionaries and equity treatises, may use "special power" to describe what modern law would call a "limited power," and the terms are interchangeable in most contexts.
POWER TO DISPOSE vs. POWER OF SALE: A power of sale is a narrower, transactional authority — typically granted to a trustee or executor — to convert property to cash. A special power to dispose of an estate is a broader testamentary or equitable authority over ultimate distribution. Do not read these as equivalent in historical sources, particularly in mortgage and trust instruments where "power of sale" has its own specialized meaning.

Why It Matters in Research
This term has low surface frequency in modern legal databases but high importance in historical equity, trust, and property research. Several navigational points:
Vocabulary instability is the primary trap. Nineteenth-century sources — including Rapalje & Lawrence and the cases they index — do not use "power of appointment" as consistently as modern treatises do. Researchers will encounter "special power to dispose," "limited power," "power of disposition," and "restricted power" used interchangeably. When searching historical reporters, use all variants.
Kentucky and similar code states are well-represented in the Rapalje & Lawrence corpus. The citation anchor in this source set (9 Bush (Ky.) 404) signals that questions about what a "will" accomplishes in the context of a power — and what counts as a valid exercise — were actively litigated in the mid-to-late nineteenth century. Researchers tracing the exercise of special powers through wills should examine whether the jurisdiction required express reference to the power in the will or permitted general residuary language to serve as exercise.
Statute of Frauds issues intersect here. The Rapalje & Lawrence entry cluster references "special promise" under the Statute of Frauds (2 N.Y. 533). Similarly, whether a written instrument was required to create or exercise a special power depended on jurisdiction and the nature of the underlying property. In land contexts, the Statute of Frauds applied; for personal property, courts varied.
The tax dimension is entirely absent from historical dictionary sources and only emerges as a research concern in the twentieth century. Do not expect pre-1900 authorities to address the estate-tax consequences of special versus general powers.
Equity court records are a primary source. Disputes over whether a donee exceeded a special power — by attempting to appoint outside the class, or to themselves — were resolved in chancery. Researchers should look to equity reporters, not just law-side reporters, for controlling doctrine.

Historical Dictionary Support
Rapalje & Lawrence does not provide a standalone entry for "Special Power to Dispose of Estate By." The entry appears as a cross-reference node within a cluster of "special" terms — special proceedings, special promise, special privilege — suggesting that the editors treated it as a term of art sufficiently defined by case law rather than requiring independent exposition. The citation pattern in the source set is characteristic of Rapalje & Lawrence's method: directing the researcher to a jurisdiction and reporter rather than offering doctrinal synthesis.
This reflects a broader limitation of the nineteenth-century American legal dictionaries: powers of appointment doctrine was still largely mediated through English equity sources (notably Sugden's treatise on powers), and American dictionaries of the period tended to defer to case-by-case development rather than articulate a unified framework. Researchers relying solely on Rapalje & Lawrence for powers doctrine will need to supplement with equity treatises and the leading state court decisions of the period.
The absence of a dedicated entry should not be read as suggesting the concept was obscure. Powers to dispose — both general and special — were sufficiently standard in conveyancing and testamentary practice that practitioners were expected to understand them without dictionary assistance.

Jurisdictional Note
Doctrine governing the creation, exercise, and validity of special powers developed unevenly across American jurisdictions in the nineteenth century, with equity states generally following English chancery precedent more closely than code-pleading states. Modern uniform law — including the Uniform Powers of Appointment Act (2013) — has substantially harmonized American doctrine, but historical research will encounter significant state-by-state variation, particularly on questions of whether a will exercises a special power by implication.
