Surety underwriting is the evaluation process a surety performs before issuing a bond. It involves reviewing the principal’s financial condition, experience, and track record to determine the level of risk.
Unlike insurance, where claims are expected, surety bonds operate on the assumption that no claim will occur.
A surety bond underwriter is the professional or entity that assesses the risk and solvency of a person or company requesting a surety bond. This role involves determining whether a bond application will be approved or rejected, and at what cost.
A surety bond company relies on underwriting to decide if it will issue a bond and at what premium.
The process considers the applicant’s character, capacity, and capital—known as the “three C’s.” This structured approach helps ensure that only businesses with the ability to meet their obligations can secure bonds.
How the Surety Underwriting Process Works
The process typically starts with an application submitted by the principal. The application includes business financial statements, credit history, and details about the specific bond requested. The underwriter then reviews this information and evaluates:
- The type and amount of bond required.
- The clarity of the bond’s performance criteria.
- The principal’s financial statements, including working capital, assets, and liabilities.
- Credit score and payment history of the business and its owners.
- Experience in the relevant industry and track record of past projects.
- Legal or regulatory issues such as tax liens, bankruptcies, or lawsuits.
If the risk level is acceptable, the application is approved and assigned a premium. The premium is usually a percentage of the bond amount, often between 0.5% and 10%.
When risk is higher, the surety may require collateral in addition to the premium. Collateral can be cash, an irrevocable letter of credit, or other assets.

Differences Between Surety Bond Underwriting and Insurance Underwriting
Factors that Influence Underwriting Decisions
Several factors affect how a surety evaluates an application. These include:
- Bond type: Bonds with complex or high-value performance criteria, such as a contract bond, often require more extensive review than a commercial bond that ensures compliance with licensing requirements.
- Financial health: Liquidity, profitability, and positive working capital reduce perceived risk.
- Credit history: A history of on-time payments supports approval, while bankruptcies or defaults increase risk.
- Experience: Demonstrated ability to complete projects of similar scope strengthens an application.
- Legal standing: Past lawsuits, tax liens, or regulatory penalties may negatively influence approval.
Good underwriters analyze the overall picture instead of making decisions based solely on one factor. For example, a company with lower credit but strong financial statements and significant industry experience may still qualify for approval.
The Three C’s of Surety Underwriting
The concept of the three C’s provides a framework for consistent evaluations:
- Character: Integrity, legal record, and history of honoring commitments.
- Capacity: Technical skills, industry expertise, and resources to complete obligations.
- Capital: Financial ability to handle bond obligations and reimburse the surety if required.
This approach ensures that applicants are judged on financial and non-financial indicators.
Outcomes of the Underwriting Process
At the conclusion of underwriting, the surety either approves or denies the application.
Approval comes with a premium rate, while denial indicates that the surety considers the risk unacceptable. In some cases, applicants can improve their standing by submitting updated financial documents, resolving outstanding debts, or providing collateral.
Some bonds bypass this process altogether. Low-risk bonds such as notary bonds, certain license bonds, or car title bonds are often pre-approved and do not require full underwriting.

Why the Process Matters
The underwriting process protects all parties involved. Obligees gain confidence that a project or obligation will be completed. Principals secure access to opportunities that require bonding. Sureties reduce exposure to financial losses by ensuring applicants are qualified.
It also helps businesses prepare stronger applications. Accurate financial records, proof of experience, and evidence of stability increase the likelihood of approval and lower premiums.
The Role of Surety Underwriting
Surety underwriting serves as the foundation of the bonding process. By evaluating risk through financial review, experience, and reputation, underwriters decide whether a principal qualifies for a bond and at what cost.
This process distinguishes bonds from insurance, as it assumes no claim will occur and places responsibility on the principal to indemnify the surety if one does.
