Definition
A bond is a formal written obligation by which one or more parties bind themselves to perform a specified act or pay a sum of money upon the occurrence of defined conditions. The term covers several distinct legal instruments that share the common structure of a binding commitment, often backed by a financial guarantee or a surety.
1. DEBT INSTRUMENT (FINANCIAL BOND): A written promise by a government, municipality, or corporation to repay borrowed money at a stated interest rate by a fixed date. The issuer receives capital; the bondholder holds the right to repayment. Municipal bonds, treasury bonds, and corporate bonds fall here.
2. SURETY OR PENAL BOND: A three-party instrument in which a principal (the obligor) and a surety jointly bind themselves to an obligee, guaranteeing performance of an obligation or payment of a penalty sum upon default. Construction performance bonds and payment bonds are the most common modern examples. If the principal fails to perform, the surety steps in to satisfy the obligation or pay the stated penalty.
3. BAIL BOND: In criminal and immigration proceedings, a bond posted to secure the release of a detained person, guaranteeing their appearance at future proceedings. The bond may be posted by the defendant, a commercial bail agent, or — in immigration matters — an approved sponsor. Forfeiture occurs upon failure to appear.
4. OFFICIAL BOND: A bond posted by a public officer or fiduciary (executor, administrator, guardian, trustee) as security for faithful performance of official duties. Breach triggers liability against the officer and, where applicable, the surety.

Common Language
Modern common usage (Wiktionary): In ordinary English, "bonds" most commonly means ties, connections, or attachments between people or things — as in "the bonds of friendship." The verb form ("bonds") simply means fastens or connects.
Historical common usage (Webster's 1913): Webster's 1913 treats the legal meaning as primary, defining "bond" as a binding agreement or obligation, and separately noting its use for financial instruments (government and corporate debt) and for physical restraints.
The gap is significant. A researcher encountering "bonds" in a legal document should immediately resist the common conversational meaning (emotional connection) and instead identify which of the legal subcategories applies — financial debt instrument, surety obligation, bail, or official fidelity bond. The physical-restraint meaning (chains, shackles) appears in older criminal and admiralty records and creates additional ambiguity in historical sources.

Common Confusion
BONDS vs. NOTES vs. DEBENTURES: In financial and municipal law, these terms are sometimes used interchangeably in older sources but carry distinct technical meanings in modern practice. A bond typically implies a secured, long-term debt obligation backed by specific assets or revenue streams. A note is generally shorter-term and may be unsecured. A debenture (more common in English law) is an unsecured bond backed only by the issuer's creditworthiness. Historical sources — including Bouvier's — do not always maintain this distinction rigorously.
SURETY BOND vs. INSURANCE POLICY: Surety bonds are frequently confused with insurance in both lay and legal contexts. A key difference: in a surety relationship, the principal is expected to indemnify the surety for any losses paid; no such expectation runs from insured to insurer. The structural difference matters when researching claims, subrogation rights, and defenses.
BAIL BOND vs. RECOGNIZANCE: A bail bond involves a third-party surety or pledged property. A recognizance is the defendant's own sworn acknowledgment of the obligation, without a separate surety instrument. Historical sources often use these terms loosely.

Recognized Forms
/SUBTYPES
Performance Bond — guarantees completion of a contract according to its terms; triggers when the principal defaults on the underlying contract.
Payment Bond — guarantees that subcontractors, laborers, and suppliers will be paid; operates alongside but independently of a performance bond in construction contexts.
Bid Bond — guarantees that a bidder will enter the contract and furnish required bonds if awarded; forfeited if the bidder withdraws after award.
Fidelity Bond — protects an employer or principal against dishonest acts (theft, fraud) by employees or fiduciaries; functions more like insurance in modern practice.
Bail Bond — secures appearance in criminal or immigration proceedings.
Official Bond — secures faithful performance of a public office or fiduciary appointment.
Municipal Bond — evidence of a governmental unit's debt obligation to bondholders.

Why It Matters in Research
The multiplicity of meanings is the central research hazard. A case or statute using "bonds" without qualification may be addressing municipal finance, construction surety law, criminal procedure, or fiduciary administration — each governed by entirely different bodies of law with different encyclopedic and statutory homes.
Municipal bond authority is constitutionally constrained in many states. Bouvier's flags a key rule: where a statute sets a borrowing limit, a municipality cannot evade that cap by invoking a general borrowing power. This principle remains live in municipal finance research and connects to constitutional debt-limitation provisions that vary by state. Researchers working with historical municipal records should identify both the statutory authorization and the constitutional ceiling applicable at the time of issuance.
For construction surety bonds, the federal Miller Act (for federal projects) and its state-law analogs ("Little Miller Acts") govern the required use of performance and payment bonds on public construction contracts. These statutes create direct rights for subcontractors and suppliers that do not exist at common law — a point historical sources predate entirely.
In immigration law, bond amounts and the standards for detention versus release have been subject to significant administrative and judicial evolution. Historical dictionary definitions are essentially useless here; the operative law is regulatory and case-driven.
Fidelity bonds appear in both employment and fiduciary contexts. When researching estate administration, guardianship, or trust accounts in historical records, the official bond is the instrument that creates surety liability against an administrator or guardian — and it is the starting point for any action against that fiduciary's surety.

Historical Dictionary Support
Bouvier's Law Dictionary addresses bonds primarily in the context of municipal borrowing authority and constitutional limitations on legislative power to authorize municipal debt. The passage in the source material reflects late-nineteenth-century concern with runaway municipal indebtedness — a historical problem that produced the constitutional debt caps still embedded in many state constitutions today. Bouvier's is useful for the public-law dimension of bonds but largely silent on construction surety bonds (a modern statutory development) and does not address immigration bonds at all, as that body of law postdates its composition.
The historical dictionaries as a class are strong on the formal legal definition of bonds as penal obligations and on the structure of official bonds for public officers and fiduciaries. They are weak on financial bonds as capital-market instruments and entirely absent on the regulatory and procedural frameworks that now govern bail and immigration bonds. Researchers should treat historical dictionary entries as useful for common-law structure and useless for modern statutory or regulatory gloss.

Jurisdictional Note
Municipal bond authority is state-constitutional in character, and the limits differ significantly across states — some impose debt ceilings tied to assessed property value, others restrict specific types of projects, and some require voter approval. Construction surety bond requirements track state-specific "Little Miller Act" statutes that vary in coverage thresholds, notice requirements, and claimant rights. Bail bond practice — including the commercial bail industry itself — is effectively prohibited in some jurisdictions (notably Canada and most of Europe) and heavily regulated at the state level in the United States.
