Definition
An executory estate is an estate or interest in land whose vesting or enjoyment depends upon the occurrence of some future contingency. No present possessory interest passes at the time the estate is created; instead, the estate remains incomplete or inchoate until the triggering event occurs — or fails to occur. The term encompasses two primary instruments through which such estates arise: executory devises and executory interests generally, including both springing and shifting executory interests.
The defining characteristic is incompleteness. The estate has been created but cannot be enjoyed — or may never vest — because something further must happen first.

Common Confusion
EXECUTORY ESTATE vs. CONTINGENT REMAINDER: These concepts are closely related and historically treated as near-equivalents in some sources. Black's notes that an executory remainder "is the same as a contingent remainder, because no present interest passes." However, the distinction matters for research: contingent remainders follow a possessory estate and are subject to the destructibility rule at common law, while executory interests (the modern successor concept) operate by cutting short a prior estate or springing up in a gap where no vested estate exists. After the Statute of Uses (1535) and the development of uses and trusts, executory interests became the preferred vehicle for future interests that could not be framed as remainders. Modern property law tends to absorb the old "executory estate" label into the category of executory interests, but historical sources use the terms inconsistently.
EXECUTORY ESTATE vs. EXECUTORY TRUST: Burrill's entry conflates the two within a single passage, which can mislead researchers. An executory trust is a distinct concept — a trust that remains incomplete because some further act by the settlor or trustee is necessary to give it full effect. The two share the word "executory" (meaning yet to be performed or completed) but operate in different doctrinal domains: executory estates concern future interests in property law; executory trusts concern the formation and enforcement of trust arrangements in equity. Do not carry findings from one category into the other without careful attention to context.

Core Elements
An executory estate in the traditional sense rests on three features:
1. FUTURE CONTINGENCY: Some event, condition, or circumstance must occur (or fail to occur) before the estate vests or becomes possessory. The contingency may be a condition precedent to vesting or an event that cuts short a prior estate.
2. ABSENCE OF PRESENT VESTED INTEREST: The estate does not presently vest in the grantee or devisee. Until the contingency is resolved, no present interest passes — distinguishing it from a vested remainder, which is already fixed in a known person subject only to the opening of possession.
3. CREATION BY DEVISE OR GRANT: Historically, executory estates arise either as executory devises (created by will, operating under the Statute of Wills) or as executory interests under a deed operating through the Statute of Uses. The instrument of creation determines which rules govern the estate's validity, duration, and ability to vest.

Recognized Forms
/SUBTYPES
EXECUTORY DEVISE: A future interest created by will that cannot take effect as a remainder because it either cuts short a prior freehold estate or springs up after a gap in seisin. Not subject to the destructibility rule applicable to contingent remainders at common law.
SPRINGING EXECUTORY INTEREST: Cuts against the grantor (or the grantor's heirs) by springing into existence at a future time, leaving a gap in possession between the prior estate's end and the executory interest's beginning.
SHIFTING EXECUTORY INTEREST: Cuts against a prior grantee by shifting the estate from one transferee to another upon the happening of a specified condition.

Why It Matters in Research
The term "executory estate" is largely a historical label. Modern property law encyclopedias and treatises have largely retired it in favor of the more precise vocabulary of "executory interests," "springing interests," and "shifting interests." Researchers working in primary sources from the seventeenth through nineteenth centuries will encounter "executory estate" frequently, but it does not map cleanly onto a single modern category — context must determine whether the source is describing what modern law calls a contingent remainder, a springing executory interest, or a shifting executory interest.
The conflation in Burrill's of executory estates and executory trusts within the same definitional block is a known trap. Early American and English equity practice sometimes used overlapping vocabulary, and researchers relying on secondary digests rather than primary sources risk importing trust-law reasoning into property-law analysis.
The Statute of Uses is the pivotal background rule. Before 1535, the concept of future interests operating through uses was developing informally; after 1535, executory interests gained formal legal recognition and created the doctrinal architecture that generated most of the nuanced vocabulary. Researchers tracing disputes involving land grants, wills, or settlements predating the statute should be especially cautious about applying post-statute definitions retroactively.
In American jurisdictions, the Rule Against Perpetuities is the doctrinal constraint most directly relevant to executory estates — contingent future interests that might vest too remotely are void. Many states have modified or abolished the common-law RAP, so the enforceability of an executory estate in a historical document depends heavily on the jurisdiction and the applicable period's version of that rule.
The bankruptcy corpus (business_132) uses "executory" in a completely different sense — executory contracts under Section 365 involve ongoing bilateral obligations in insolvency proceedings. The similarity is etymological, not doctrinal. Do not cross-contaminate research across these domains.

Historical Dictionary Support
Black's and Burrill's agree on the core: an executory estate depends on a future contingency and carries no present vested interest. Both sources identify the executory devise and the contingent/executory remainder as the primary vehicles.
Black's treatment is more analytical, flagging the near-equivalence between executory remainders and contingent remainders while stopping short of a full structural account of springing versus shifting interests. This reflects the dictionary's tendency to synthesize rather than to trace doctrinal evolution — useful for identifying the label but insufficient for understanding how the estate operates in practice.
Burrill's is more compressed and, as noted, folds the executory trust definition into the same entry without adequate separation. The citations to Crabb's Real Property and White's Leading Equity Cases are genuine reference points in mid-nineteenth-century property and equity practice, useful for researchers tracing American adoption of English property doctrine.
Neither source adequately distinguishes the post-Statute of Uses executory interest from the pre-statute contingent remainder, which is the central analytical gap a researcher must fill using treatise literature (Blackstone, Kent's Commentaries, and later Simes on Future Interests) rather than these dictionary entries alone.

Jurisdictional Note
American states vary substantially in whether they retain the common-law destructibility rule for contingent remainders (which historically distinguished contingent remainders from executory interests), with most modern jurisdictions having abolished it. The Rule Against Perpetuities, which governs when an executory estate must vest or fail, has been modified by statute in a large number of states — including through wait-and-see reforms and dynasty trust legislation. The enforceability of any specific executory estate in historical title documents requires jurisdiction-specific RAP analysis.
