A B C D E F G H I L M N O P R S T U W

Admitted Surety (Admitted Insurer): A surety company that has been licensed (admitted) by a state's insurance regulatory authority to write bonds in that state. Most state licensing boards require bonds to be issued by an admitted surety — a bond from a non-admitted surety may be rejected. You can verify whether a surety is admitted in your state through your state's insurance department website or the NAIC consumer information portal.
Aggregate Limit: The maximum total amount a surety will pay across all claims filed against a single bond during its term. Equal to the penal sum (face value) of the bond. If multiple claims are filed that together exceed the aggregate limit, the surety pays up to the aggregate limit and claimants must pursue any remaining balance through civil court against the contractor directly.
Attorney-in-Fact: The individual — typically a licensed bond agent or surety employee — who has been granted authority by the surety company to execute (sign) bonds on the surety's behalf. This authority is documented in the Power of Attorney attached to the bond certificate. The bond is not valid unless the attorney-in-fact's signature is accompanied by a valid, current Power of Attorney.

Bid Bond: A surety bond submitted with a contract bid that guarantees if the contractor's bid is accepted, the contractor will enter the contract and provide required performance and payment bonds. The face value is typically 5–10% of the bid amount. If the contractor refuses to enter the contract after winning the bid, the surety pays the difference in cost between the winning bid and the next-lowest bid, up to the bid bond amount. Bid bonds are used primarily on public works projects.
Bond Certificate: The physical or digital document that constitutes the surety bond — the legal instrument that creates the three-party obligation. It names the principal, obligee, and surety; states the penal sum; describes the conditions; and is executed by an authorized representative of the surety. The bond certificate must be submitted to the licensing board (along with its accompanying Power of Attorney) to satisfy a licensing bond requirement.
Bond Claim: A formal demand made against a surety bond by an eligible claimant (typically the obligee or a party protected by the bond's conditions) alleging that the principal has breached the bond's conditions and seeking financial recovery up to the bond's penal sum. Claims must typically be made in writing to the surety. The surety investigates the claim, may deny it, settle it, or pay it — and if paid, pursues the principal for reimbursement under the indemnity agreement.
Bond Form: The specific document template on which a surety bond is issued. Some states require contractors to use the state's own bond form (issued by the licensing board) rather than a generic surety bond form. Others accept any standard AIA or SFAA bond form. When a state requires its own specific form, you must verify that your surety will issue the bond on that form — not all sureties work with all state-specific forms.

Cancellation: Termination of a surety bond before its natural end date (for term bonds) or by formal notice (for continuous bonds). Either the surety or the principal can initiate cancellation. Surety-initiated cancellation typically requires 30–60 days written notice to both the principal and the obligee (the licensing board). Principal-initiated cancellation also requires written notice per the bond's terms. When a contractor bond is cancelled, the licensing board is notified and the contractor's license may be suspended.
Claim Period: The time window during which a valid claim can be filed against a bond. For continuous bonds, this is typically one to two years from the date the alleged harm occurred — not from when the bond was issued. Claims filed outside this window are typically denied as untimely. Even after a bond is cancelled, claims for acts that occurred during the bond period may still be filed within the claim period.
Collateral: Cash, a letter of credit, or other assets required by a surety as security in addition to the indemnity agreement. Collateral is required for very high-risk applicants — contractors with very low credit scores, prior paid claims, or large bond amounts that the surety cannot adequately price through premiums alone. Collateral is held by the surety for the bond term and returned when the bond is cancelled (assuming no outstanding claims). Unlike premium, collateral is theoretically recoverable.
Conditions: The specific obligations the principal must fulfill for the bond to remain in good standing — the substantive core of what the bond guarantees. In a contractor license bond, the conditions typically describe compliance with licensing law, permit requirements, and financial obligations. If the principal breaches the conditions, the obligee has the right to file a claim. The conditions section is the most important part of the bond form to read carefully.
Continuous Bond: A bond with no fixed expiration date that remains in force until cancelled by either party with proper notice. Most contractor license bonds are continuous. The contractor pays an annual premium to maintain the bond, but there is no automatic expiration. Failing to pay the annual premium triggers the cancellation process (not immediate lapse) — the surety must still provide the required notice before the bond terminates.

Default: The principal's failure to fulfill the obligations guaranteed by the bond — the triggering event for a bond claim. In a contractor license bond context, default might mean abandoning a job, failing to obtain permits, or violating licensing law. In a performance bond context, default means failing to complete the contracted project. The surety's obligation to pay is triggered by the principal's default and a valid claim by the obligee.
Dual Indemnification: When both the business entity (LLC or corporation) and the individual owner(s) are required to sign the indemnity agreement. Most sureties require dual indemnification for small to mid-sized contractor bonds because small business entities have limited assets — requiring the individual to personally co-indemnify ensures the surety has recourse against personal assets if the business cannot repay a paid claim.

Earned Premium: The portion of the annual premium that the surety considers "earned" and is not refundable upon cancellation. Most sureties have a minimum earned premium — typically 25% of the annual premium or a flat minimum (e.g. $75), whichever is greater. If you cancel a bond shortly after purchasing it, you may receive a partial refund of the unearned portion minus the earned minimum.
Execution / Execution Date: The act of signing the bond — and the date on which the bond was signed by the surety's authorized representative. The execution date is distinct from the effective date (when coverage begins). Most licensing boards care primarily about the effective date, but some require the execution and effective dates to match. Always check which date your licensing board uses to determine when the bond is "active."

Fidelity Bond: A bond that protects against financial loss caused by employee dishonesty, theft, or fraud. Unlike a surety bond (which protects the obligee from the principal's failure to perform), a fidelity bond protects the policyholder (or their clients) from employees. When a contractor says they're "bonded against employee theft," they mean they have a fidelity bond. This is entirely separate from a contractor license bond.

General Indemnity Agreement (GIA): The contractual document signed by the contractor (and typically their personal guarantors) that obligates them to reimburse the surety for any amounts paid on bond claims, plus investigation costs and legal fees. The GIA is the mechanism that makes a surety bond fundamentally different from insurance: the surety is not absorbing the loss — they are extending credit, with the expectation of full repayment from the principal. Signing a GIA means accepting personal liability for claims, not just business liability.

High-Risk Bond / Specialty Market: Bonds issued by surety companies that specialize in applicants who cannot qualify for standard-market rates — typically due to poor credit, prior claims, financial difficulties, or prior license disciplinary action. High-risk bond premiums can run 10–15% of the bond face value annually, significantly higher than the 1–2% rates available to good-credit applicants. High-risk bonds may also require collateral.

Indemnity / Indemnification: The obligation of the principal to reimburse the surety for any amounts paid on a bond claim. This is the core economic principle of surety bonding: the surety pays claims on behalf of the principal, but the principal owes that money back. Indemnification extends beyond the claim amount to include the surety's investigation costs and legal fees in most GIAs. The indemnity obligation can extend to personal assets when personal guarantors sign the GIA.
Indemnitor: Any party who signs the indemnity agreement and accepts personal liability for reimbursing the surety. On most small contractor bonds, the indemnitor is the contractor themselves (for sole proprietors) or the business owner(s) and the business entity (for LLCs and corporations). Sureties may require additional indemnitors — such as spouses with significant assets — in certain high-risk situations.

License Bond (Contractor License Bond): The most common bond type required for contractor licensing. Guarantees the contractor's compliance with state licensing law — including permit requirements, job completion obligations, and financial responsibilities specified by the licensing statute. The obligee is typically the state licensing board. Unlike performance bonds (which guarantee specific project completion), a license bond covers all licensed work during the bond period.
Little Miller Act: State-level equivalents of the federal Miller Act, requiring performance and payment bonds on state and local public works construction contracts. Each state's Little Miller Act specifies the dollar threshold above which bonds are required, the bond amounts (typically 100% of contract value), and the rights of subcontractors and suppliers to file claims. Requirements vary significantly by state.

Maintenance Bond: A bond guaranteeing that a contractor will correct defects in completed work during a specified warranty period after project completion. Sometimes included within a performance bond; sometimes issued as a separate instrument. Common on public works projects and large commercial construction contracts where the project owner wants assurance that defects discovered post-completion will be remedied at the contractor's expense.
Miller Act: Federal law (40 U.S.C. §§ 3131–3134) requiring contractors on federal construction contracts over $150,000 to furnish performance bonds and payment bonds, each typically at 100% of the contract value. The payment bond specifically protects subcontractors and suppliers who furnish labor or materials on federal projects. Subcontractors must provide written notice to the prime contractor within 90 days of last furnishing labor/materials to preserve their payment bond claim rights.

NAIC (National Association of Insurance Commissioners): The organization of state insurance regulators that coordinates insurance regulation across states. NAIC maintains a consumer information portal where you can verify whether a surety company is licensed (admitted) in a specific state. Contractors can use the NAIC lookup at content.naic.org/cis to verify surety admission status before purchasing a bond.
Notice of Claim: The formal written notification to the surety by a claimant that a claim is being made against the bond. Most bonds specify that claims must be made in writing within a specific time period. The notice starts the investigation clock. Contractors who receive notice that a claim has been filed should respond promptly with their documentation — failure to respond can result in a default determination against them.

Obligee: The party for whose benefit the bond is written — the party protected by the bond's guarantee and with the right to file a claim. For a contractor license bond, the obligee is typically the state licensing board (e.g., "California Contractors State License Board" or "Oregon Construction Contractors Board"). For a performance bond, the obligee is the project owner. The obligee's name on the bond must exactly match the name required by the licensing board or contract.

Payment Bond: A surety bond guaranteeing that a prime contractor will pay subcontractors, laborers, and material suppliers on a project. Required alongside performance bonds on most public works projects under the Miller Act and state Little Miller Acts. Protects subs and suppliers from non-payment without having to file mechanics' liens against the owner's property. Unpaid subs on projects with payment bonds should file claims directly with the surety — within the time limits specified by applicable law.
Penal Sum: The maximum dollar amount a surety will pay on all claims against a bond — the bond's face value. Expressed on the bond certificate in numerals and words. For a $15,000 contractor license bond, $15,000 is the penal sum. The penal sum is not what you paid (that's the premium); it's the maximum liability coverage. Multiple claims that together exceed the penal sum result in the surety paying up to the penal sum and claimants pursuing the balance through civil court.
Performance Bond: A surety bond guaranteeing that a contractor will complete a specific project according to the contract terms, schedule, and specifications. If the contractor defaults, the surety must arrange completion — either by financing the original contractor, hiring a replacement contractor, or paying the owner up to the bond amount. Performance bonds are project-specific, typically at 100% of contract value, and are distinct from contractor license bonds.
Permit Bond: A bond required by a city, county, or municipal authority for specific permitted work — particularly work in public rights-of-way or on public infrastructure. Guarantees the contractor will complete the permitted work and restore the site to required conditions. Permit bonds are job-specific and are required in addition to (not instead of) the contractor's license bond.
Power of Attorney (POA): The document attached to a bond certificate that authorizes the person who signed the bond on the surety's behalf to do so. The POA proves the signer had legal authority to bind the surety. Always attach the POA to the bond when submitting to a licensing board — they are a package. Never separate them. If a POA is missing, the bond may be rejected as improperly executed.
Premium: The annual fee paid by the contractor to maintain the surety bond — calculated as a percentage (the rate) of the bond's penal sum. The premium is the cost of the surety's guarantee for one year. It is not applied toward claim payments — claims are paid from the surety's funds and the contractor must reimburse the surety separately under the indemnity agreement. Premium rates are set primarily by credit score: 1–2% for good credit, up to 15% for poor credit.
Principal: The contractor or business entity that purchases the bond and whose performance is being guaranteed to the obligee. The principal is the party obligated under the indemnity agreement to reimburse the surety for any paid claims. For a contractor license bond, the principal is the licensed contractor or their business entity. The principal's name on the bond must match the name on their license application exactly.

Rate: The percentage of the bond's penal sum that the contractor pays annually as a premium. Set by the surety's underwriting department based primarily on the contractor's credit score, with modifications for bond size, claims history, and business financial strength. Standard market rates for good-credit contractors: 1–2%. High-risk market rates: 5–15%. The rate multiplied by the penal sum equals the annual premium.
Renewal: The annual process of maintaining a continuous bond by paying the next year's premium. For continuous bonds, renewal keeps the bond active without requiring new documentation to the licensing board. The surety may re-underwrite at renewal, adjusting the rate if the contractor's credit or risk profile has changed. Failure to pay the renewal premium triggers the cancellation process.
Rider / Endorsement: An amendment to an existing bond that changes one or more of its terms — typically used to increase the penal sum, change the principal's name (after business restructuring), or extend the bond's coverage. A rider is attached to the original bond certificate and must be submitted to the licensing board if the change affects a bonding requirement (e.g., a bond amount increase).

Soft Pull / Hard Pull: Two types of credit inquiries. A soft pull accesses your credit report for informational purposes and does not affect your credit score. A hard pull (also called a hard inquiry) is recorded on your credit report and can slightly lower your score. When applying for a bond, some sureties run a soft pull for quoting and a hard pull only when you proceed to bind coverage. Ask upfront which type of pull will be made.
Subrogation: The legal right of the surety, after paying a claim, to step into the claimant's shoes and pursue recovery from the principal. After the surety pays an obligee's bond claim, subrogation allows the surety to sue the contractor for reimbursement using the same legal rights the obligee would have had. Subrogation is one of the mechanisms through which sureties recover paid claim amounts from defaulting contractors.
Surety (Surety Company): The licensed insurance or surety company that issues the bond, guarantees the principal's performance to the obligee, and pays valid claims. The surety is not a neutral party — it is a financial guarantor that extends its creditworthiness to back the contractor's obligations, with the expectation of full repayment from the contractor if a claim is paid. Sureties are regulated by state insurance departments and must be admitted in each state where they write bonds.
Surety Bond: A three-party financial guarantee instrument in which a surety company guarantees to an obligee that a principal will fulfill specific obligations. If the principal fails, the surety pays the obligee up to the bond's penal sum — and then recovers from the principal under the indemnity agreement. A surety bond is not insurance: it transfers risk to the obligee's benefit, not the principal's, and the principal must repay any claims paid.
Surplus Lines: Insurance and bonds written by non-admitted (unlicensed) insurers in a state, placed through a licensed surplus lines broker. Surplus lines carriers can write risks that admitted carriers decline. Some state licensing boards accept surplus lines bonds; others do not — check your board's requirements. Surplus lines bonds are generally more expensive than admitted carrier bonds and have less regulatory protection for the insured.

Term Bond: A bond issued for a specific period — typically one year — that expires automatically at the end of the term unless renewed. Unlike a continuous bond, which stays active until cancelled, a term bond terminates on its expiration date. If a term bond is not renewed before expiration, the bond lapses and the contractor's license may be immediately suspended. Less common for contractor license bonds than continuous bonds.
Three-Party Structure: The fundamental structure of every surety bond: (1) the principal (contractor), (2) the surety (bonding company), and (3) the obligee (licensing board or project owner). This three-party structure distinguishes surety bonds from insurance policies, which are two-party agreements. In a bond, the surety's guarantee runs to the obligee — not to the principal — and the principal has reimbursement obligations to the surety.

Underwriting: The process by which a surety evaluates an applicant's risk and sets the bond premium rate. For small license bonds (under $50,000), underwriting is typically automated — credit score drives an instant rate determination. For larger bonds or applicants with borderline credit, an underwriter manually reviews financial statements, credit history, claims history, and other factors. The underwriter's goal is to price the bond at a rate that reflects the probability the surety will have to pay a claim and the probability of recovering that payment from the contractor.

Work-in-Progress (WIP) Schedule: A financial schedule showing all of a contractor's current active projects, the contract values, amounts billed to date, amounts remaining to bill, and estimated completion dates. Sureties use WIP schedules when underwriting larger performance bonds to assess the contractor's current workload capacity and financial exposure. A contractor taking on a new large project while already fully committed to existing projects presents higher completion risk than one with available capacity.
