Definition
Control is a multi-context legal term referring broadly to the power, authority, or practical ability to direct, restrain, or determine the conduct, use, or disposition of a person, entity, asset, or activity. Its precise meaning shifts substantially depending on the legal domain in which it appears.
1. Corporate and agency law. The power to direct or govern the management and policies of an entity, whether exercised through majority stock ownership, board composition, contractual authority, or other means. Control in this sense need not be absolute — practical or effective dominance may suffice.
2. Secured transactions and personal property. The method of perfecting a security interest in certain types of collateral — particularly deposit accounts, investment property, and electronic documents — by achieving a relationship with the asset or its custodian that gives the secured party authority to direct disposition without further consent of the debtor.
3. Railroad and transportation law. The immediate or executive control exercised by a carrier over a line, property, or operation through its officers and agents acting under board authority. Anderson notes this distinction between formal ownership and operational control in the railroad context, tying control to the practical exercise of authority rather than legal title.
4. Regulatory law. The power to restrain, limit, or govern activity — used in statutes authorizing agencies to control conduct, substances, or commerce. Control in this sense overlaps substantially with "regulate," though it often implies a more direct or executive function than regulatory supervision.
5. Municipal and street law. Anderson notes that control is a necessary incident to the regulation of city streets — the practical authority to manage and direct use, not merely to set rules for it.

Common Language
Modern common usage (Wiktionary): To exercise influence over; to suggest or dictate behavior; to hold in check, curb, or restrain; to verify accuracy by comparison with another account.
Historical common usage (Webster's 1913): Power or authority to check or restrain; restraining or regulating influence; superintendence; government — as in parental control. Also, historically, a duplicate register kept to check another account.
The common meaning of control — influence, restraint, oversight — maps loosely onto most legal uses, but obscures a critical legal distinction: in law, control is often a term of art with specific threshold requirements and legal consequences that mere influence does not satisfy. A minority shareholder may influence a corporation without controlling it. A lender may monitor a borrower's finances without having control over a deposit account in the secured transactions sense. Researchers should not assume that factual dominance or practical influence meets the legal standard for control in any given context.

Common Confusion
Control vs. ownership. Control and ownership are frequently conflated but are legally distinct. An entity may own an asset without controlling it (a pledgor who has delivered collateral) or control it without owning it (a secured party with control over a deposit account, a parent company directing a subsidiary it holds through intermediate entities). Many regulatory and liability frameworks — including securities law, sanctions regimes, and corporate alter-ego analysis — turn on control rather than ownership, making the distinction outcome-determinative.
Control vs. regulate. Anderson explicitly cross-references these terms. "Regulate" typically implies the setting of rules and standards governing conduct; "control" implies more direct, executive authority to direct or restrain. In municipal street law, Anderson treats control as the operational component that makes regulation effective. In practice, statutes may use the terms interchangeably, and researchers should read the specific statutory or contractual context rather than relying on a categorical distinction.

Core Elements
In the secured transactions context — where control has the most formally developed legal meaning — the elements of control vary by collateral type but generally require:
1. The secured party has the ability to direct disposition of the collateral (e.g., to give instructions to a bank, securities intermediary, or commodity intermediary) without further consent of the debtor or obligor.
2. That ability arises through a qualifying relationship: either the secured party is itself the account holder or intermediary, or a control agreement exists among the debtor, the secured party, and the relevant institution.
3. The arrangement is recognized by the institution holding or maintaining the collateral.
In corporate and regulatory contexts, control analysis is typically fact-intensive and may look to: percentage of voting interests held, board appointment rights, contractual veto powers, day-to-day operational authority, and whether another party is in a position to direct or cause the direction of management.

Why It Matters in Research
Control is one of the most context-dependent terms in the Law Mind corpus. A search returning results across corporate law, secured transactions, administrative regulation, and municipal law will surface the term in radically different senses, and conflating them will mislead research.
The Anderson entry is narrow and historically situated in the railroad era — its description of "immediate or executive control" reflects a period when the operative question was which carrier exercised day-to-day authority over a line, not the modern securities or regulatory sense. Researchers using Anderson as a primary reference for control in modern transactional or regulatory contexts should treat it as background only.
The secured transactions corpus deserves particular attention. The legal meaning of control in that context is statutory and technical — it is a perfection method with a defined legal test, not a general characterization of the parties' relationship. Researchers analyzing perfection disputes should work from the statutory text and not import the broader common or corporate-law meaning of control.
In the sanctions and export controls context (OFAC, EAR), control triggers jurisdictional reach over foreign entities and transactions. The regulatory definition of control in that framework is its own term of art, often including presumptions based on ownership thresholds (commonly 50% or more) that may differ from how control is assessed in other bodies of law.
Jurisdictional and statutory variation is significant. Federal statutes, state corporation codes, the UCC, and regulatory regimes each define or apply control differently. Cross-corpus research on this term requires tracking which definition governs in each source.

Historical Dictionary Support
Anderson's Dictionary of Law does not offer a standalone definition of control, instead directing the reader to PROHIBITION and REGULATE — a choice that signals Anderson treated control as a functional rather than formal legal concept. The illustrative entry drawn from railroad contract law captures one of control's historically important legal uses: distinguishing between a railroad company that merely has a financial interest in another road and one that exercises operational authority over it through officers and agents. This was a live question in the railroad consolidation era, when contract language needed to distinguish oversight from management.
Anderson's linking of control to regulation of city streets reflects the 19th-century municipal law context in which cities asserted authority over street use — control being the practical power that gave regulatory authority its operative effect.
What Anderson does not address — and what historical dictionaries generally miss — is the technical statutory meaning of control in secured transactions law, the modern corporate law frameworks for determining control in M&A and securities contexts, and the administrative law uses of control in regulatory enforcement. These meanings developed largely in the 20th and 21st centuries and are not captured in the shelf sources.

Jurisdictional Note
The UCC definition of control (Articles 8 and 9) has been adopted in substantially uniform form across U.S. jurisdictions, but state-specific variations exist. Corporate law definitions of control vary by state — Delaware courts apply a fact-intensive standard, while some states use statutory thresholds. In federal regulatory law (OFAC, FTC, banking regulators), control has agency-specific definitions that may not align with state corporate or UCC standards.
