Definition
To execute means to complete, give legal effect to, or carry out a legal instrument, process, or command. The word carries distinct meanings depending on context, and a researcher must determine which sense is operative before relying on any source.
1. To execute a document (deed, contract, will, mortgage, lease): To perform the acts necessary to give the instrument legal validity and force. For a deed, this traditionally required signing, sealing, and delivery — all three. For a contract, execution means performing the formalities sufficient to make it binding. Execution in this sense marks the moment a document transitions from a draft to a legally operative instrument.
2. To execute a writ, judgment, or court order: To carry it out; to enforce or give effect to the court's command. A sheriff executes a writ of possession by physically enforcing it. A judgment creditor executes a judgment by levying on the debtor's property.
3. To execute a statute or legal rule: In the context of uses and equitable interests, a statute is said to "execute" a use when it converts an equitable interest into a legal one — the classic operation of the Statute of Uses (1536). This sense is archaic in practice but essential for reading pre-20th century equity materials.
4. To execute a person: To carry out a death sentence lawfully imposed by a court. The condemned is said to have been "executed" upon fulfillment of the capital sentence.
5. (Computing/Regulatory) To run or carry out a program, algorithm, or administrative function. This usage appears in modern regulatory and technology law contexts.

Common Language
Modern common usage (Wiktionary): To kill, especially as punishment for a capital crime; to carry out or put into effect; to perform; to start or run (a computer program).
Historical common usage (Webster's 1913): To follow out or through to the end; to carry out into complete effect; to complete; to finish; to perform. Also, to complete a legal instrument by signing, sealing, and delivering.
The gap matters most in legal document drafting and transactional research. In ordinary speech, "execute" most often means to kill or simply to do something. In legal instruments and transactional practice, execute means to perform the specific formal acts — signing, sealing, acknowledgment, delivery — that give the document legal operative force. A document that is signed but not delivered, for example, may be "signed" in common usage but not "executed" in the legal sense. This distinction is frequently obscured in lay descriptions of transactional events and can create ambiguity in historical records.

Common Confusion
EXECUTE vs. PERFORM vs. ENFORCE: These three words are often used interchangeably in non-legal writing but carry distinct meanings in law. To execute a contract is to complete the formal acts making it binding; to perform a contract is to fulfill its substantive obligations over time; to enforce a contract is to compel performance through legal process. A fully executed contract is one where all parties have completed their formal obligations — it is not necessarily one that has been performed in full. Many historical treatises use "execute" loosely in the sense of "perform," requiring care when reading older authorities.
EXECUTE (a document) vs. EXECUTE (a judgment): The document sense refers to creation and formalization; the judgment sense refers to post-judgment collection and enforcement. Execution of judgment is governed by separate procedural rules and produces different legal consequences than execution of an instrument. These two uses frequently appear in close proximity in older opinions without signal, requiring the reader to derive meaning from context.

Recognized Forms
/SUBTYPES
Fully executed: A transaction or instrument in which all parties have completed the formalities required to give it effect. Contrasted with executory.
Partially executed: An instrument or agreement where one party has completed performance but the other has not. This distinction carries significant consequences in equity and in contract law.
Execute under seal: The historical form of document execution requiring a wax or embossed seal in addition to signature. Seal requirements have been substantially abolished or modified in most U.S. jurisdictions, but the phrase persists in forms and historical documents.

Why It Matters in Research
The multi-valence of "execute" is a consistent research hazard. In any pre-20th century legal source, "execute" may refer to document formalization, writ enforcement, the operation of the Statute of Uses on equitable interests, or capital punishment — sometimes in the same paragraph. Context is the only reliable disambiguator.
For transactional document research, the question of what acts were required to "execute" a particular instrument varied by instrument type, jurisdiction, and era. Deeds historically required signing, sealing, and delivery; the seal requirement eroded across U.S. jurisdictions during the 19th and 20th centuries but was retained longer in some states and in federal practice. Sources that describe a document as "executed" without specifying the formalities actually performed may be unreliable for determining whether the instrument was legally operative.
For writ and judgment enforcement research, "execution" triggers a distinct body of procedural law — exemptions, levy, sale, return — that is functionally separate from the underlying judgment. Researchers tracing collections, enforcement actions, or creditor-debtor disputes must track both the judgment and the execution proceeding as separate events in court records.
The Statute of Uses sense of "execute" is virtually never meant in modern materials but appears throughout equity treatises, conveyancing works, and property law texts from the 16th through 19th centuries. Failure to recognize this usage will produce misreading of any source discussing uses, trusts, or cestui que use doctrine.
For criminal law research, "execute" in the capital punishment sense is well-defined but generates its own corpus of constitutional litigation. The execution of a death sentence involves distinct procedural requirements separate from the underlying conviction and sentence, and those requirements have evolved substantially through Eighth Amendment jurisprudence.

Historical Dictionary Support
The historical dictionaries agree on the core cluster of meanings: complete, perfect, carry out, give effect to. All sources treat document execution as requiring the full formality package — signing, sealing, delivery — though they vary in how explicitly they flag that all three are required and that signing alone is insufficient. Burrill is the most precise on this point, noting that a deed "has no operation or effect, until executed, that is, signed, sealed and delivered." Black's (both editions) and Bouvier track this closely.
Anderson's Dictionary of Law offers the most practically useful note for researchers: the word "may mean, as in popular speech, to sign, or to sign and deliver" — acknowledging that popular and legal usage diverged even in the 19th century. This is a valuable caution for interpreting lay documents, correspondence, and commercial records that use "execute" loosely.
Bouvier specifically addresses the Statute of Uses sense ("to execute a use is to merge or unite the equitable estate of the cestui que use in the legal estate"), which Black's 2nd edition also covers. Rapalje & Lawrence's preserved fragment is not helpful on this term — the entry as preserved addresses unrelated subject matter.
None of the historical sources address the modern administrative or computing senses, which are entirely post-historical for this corpus. The capital punishment sense is mentioned in Black's ("to fulfill the sentence of the law upon a person judicially condemned") but not developed; researchers working on capital punishment history will need to supplement with criminal law treatises and reports.

Jurisdictional Note
Seal requirements for document execution varied significantly across states and were eliminated at different times. Some states retain nominal seal requirements for specific instrument types (certain deeds, corporate instruments). Federal instruments may follow different rules. Researchers working with instruments from specific jurisdictions should verify local formality requirements as of the date the instrument was made.
