The principal in a surety bond is the person or business that buys the bond and promises to carry out a specific obligation — completing a construction project, following licensing rules, managing someone else’s money, or whatever else the bond covers. If the principal fails to deliver, the surety company pays the harmed party, and then the principal owes the surety every dollar it paid out, plus costs. That reimbursement duty is what sets the principal apart from an ordinary insured, and it’s the part most people don’t see coming.
The Principal’s Place in the Three-Party Relationship
A surety bond always involves three parties. The principal is the one with the obligation. The obligee is the party who requires the bond and benefits from it, often a government agency, project owner, or court. The surety is the company that issues the bond and financially backs the principal’s promise. When a federal law requires a surety bond, the surety must be a corporation authorized to guarantee bonds under federal or state law.1Office of the Law Revision Counsel. 31 U.S. Code 9304 – Surety Corporations
The flow is straightforward. The obligee tells the principal it needs a guarantee before work can proceed or a license can issue. The principal goes to a surety, pays a premium, and the surety issues the bond. The surety is now telling the obligee that if the principal doesn’t perform, the obligee will be made whole. What the obligee doesn’t see — and what the principal often underestimates — is that the surety isn’t absorbing that risk the way an insurer would.
Why the Principal Carries the Real Risk
With a standard insurance policy, the insurer expects to pay claims. Premiums from thousands of policyholders fund those payouts, and when your building burns and the insurer writes a check for $200,000, no bill follows.
Surety bonds work on the opposite assumption. The surety expects to pay zero claims. It is lending its credit to the principal, vouching for the principal’s ability to perform. If a claim is filed and the surety pays the obligee, the surety will turn around and collect every dollar from the principal, along with legal fees and investigation costs. The mechanism for that collection is signed before the bond is ever issued.
The General Indemnity Agreement
Before a surety issues a bond, the principal signs a General Indemnity Agreement, or GIA. It is the single most important document in the surety relationship, and it is the one most principals skim.
The GIA gives the surety broad legal rights to recover from the principal whatever it pays on the principal’s behalf, including court costs, attorneys’ fees, and investigation expenses. If the principal is a business owner, the GIA typically requires a personal guarantee, which puts the owner’s personal assets on the line, not just the company’s. Married owners should expect their spouse to sign as well. The reason is practical: sureties want to prevent owners from shifting personal assets into a spouse’s name to avoid repayment. Some GIAs must be notarized before they take effect.
The agreement may also allow the surety to demand reimbursement once its liability is fixed, even before it has actually paid the obligee. In practice, the principal’s financial exposure begins the moment a valid claim is established, not when the surety settles it.
What a Principal Is Responsible For
The core duty is simple to state and harder to live with: do what the bond says you’ll do. The specifics depend on the type of bond. Complete the project on time and to specification. Follow the licensing regulations. Pay your subcontractors and suppliers. Manage the estate honestly.
Beyond performing the underlying obligation, the principal is responsible for three things that come up every time a claim is filed:
- Reimbursing the surety for the full amount of any claim payment, plus the costs the surety incurred handling it.
- Cooperating with the surety’s investigation. When a claim comes in, the surety collects facts, reviews documentation, and assesses its exposure. Going silent or turning adversarial makes everything worse.
- Maintaining the financial condition the surety underwrote. Significant deterioration — unpaid taxes, new liens, bankruptcy — can trigger consequences including cancellation of the bond.
When Someone Becomes a Principal
Almost nobody buys a surety bond voluntarily. Bonds are required by someone else as a condition of doing business or carrying out a legal responsibility, and the person required to post the bond becomes the principal.
Licensing and Permits
Government agencies at every level require certain businesses to carry surety bonds before they can operate. These commercial bonds protect the public against fraud and ensure compliance with applicable laws and regulations.2U.S. Small Business Administration. Surety Bonds Auto dealers, contractors, notaries public, employment agencies, and mortgage brokers all commonly need one. The required amount varies by industry, jurisdiction, and sometimes the size of the business.
Construction Projects
Federal law requires performance and payment bonds on any federal construction contract exceeding $100,000.3Office of the Law Revision Counsel. 40 U.S. Code 3131 – Bonds of Contractors of Public Buildings or Works The performance bond guarantees the contractor will complete the project according to the contract. The payment bond protects subcontractors and material suppliers by guaranteeing they will be paid. On federal contracts, both bonds must typically equal 100% of the contract price.4Acquisition.GOV. 52.228-15 Performance and Payment Bonds-Construction
A subcontractor or supplier who hasn’t been paid in full within 90 days of completing their work can sue directly on the payment bond.5Office of the Law Revision Counsel. 40 U.S. Code 3133 – Right To Bring a Civil Action on a Payment Bond The surety pays the claim; the principal contractor then owes the surety back under the indemnity agreement.
Court-Ordered Bonds
Courts require surety bonds in several situations, most often when someone is appointed to manage another person’s finances or estate. The Department of Veterans Affairs, for example, requires corporate surety bonds for individual fiduciaries managing veterans’ estates, with the bond amount set to cover the value of the estate plus the income expected during the next accounting period.6eCFR. 38 CFR 14.709 – Surety Bonds; Court-Appointed Fiduciary Appeal bonds and other judicial bonds fall into this category as well.
What It Takes to Qualify as a Principal
Getting approved for a surety bond is closer to applying for a loan than buying insurance. The surety is deciding whether you’re likely to perform without ever triggering a claim. The factors it weighs depend on the type and size of the bond, but a few come up every time.
Credit history is the single biggest factor for most commercial and license bonds. Principals with scores above 700 generally qualify for the best rates. Below 670, most underwriters flag the application as higher risk, which means higher premiums or additional requirements. Scores below 600 make bonding significantly more expensive without necessarily making it impossible.
Financial statements matter most for construction and large commercial bonds. Sureties typically want three years of fiscal year-end statements prepared by an independent CPA — balance sheets, income statements, cash flow statements, and statements of retained earnings. Contractors should also expect to provide a current Work in Progress schedule showing each active project’s contract amount, costs to date, billings, and estimated completion date.
Industry experience and capacity round out the picture. A surety wants to see that the principal has successfully completed similar work and has the organizational depth to handle what’s being bonded. For contractors, that includes banking relationships, credit lines, and depository balances.
Principals with weak credit or thin history aren’t automatically shut out. Specialized programs exist for higher-risk applicants, and the SBA’s Surety Bond Guarantee Program helps small businesses that might not qualify on their own. The SBA guarantees 80% to 90% of the surety’s loss on individual contracts up to $9 million, or up to $14 million on federal contracts when a contracting officer certifies the guarantee is necessary.7Library of Congress.

Collateral When Credit Isn’t Enough
When a principal’s finances fall short of standard underwriting, the surety may require collateral before issuing the bond. Acceptable collateral is generally limited to highly liquid instruments: cash, which the surety can access immediately if a claim arises; an irrevocable letter of credit from a bank, payable to the surety on demand; and U.S. Treasury securities, typically reserved for bonds with face amounts above $5 million.
Sureties generally do not accept real property, tangible business assets, or liens. If a claim hits, the surety needs funds quickly, and liquidating a building or a fleet of trucks takes too long.
What a Principal Stands to Lose
The worst outcome for a principal isn’t the premium. It’s a paid claim followed by the surety’s indemnity demand, enforced against both the business and, through the personal guarantee, the owner’s personal assets. The GIA gives the surety the legal tools to collect; the principal’s financial condition determines how painful that collection becomes.
Cancellation is the other serious risk. A surety can end its obligation to cover future transactions under a bond by giving written notice to the principal and the relevant government authority. Federal regulations treat 30 days as presumptively reasonable notice unless the surety shows a shorter period is justified.8eCFR. 19 CFR 113.27 – Effective Dates of Termination of Bond Once a bond is terminated, the principal cannot conduct any activity requiring the bond until a replacement is in place. For a licensed business, that often means operations stop. Securing a replacement is harder if cancellation was triggered by a claim or by deteriorating finances, which is exactly when the principal most needs continuity.
Being the principal, in the end, means two commitments at once: performing the obligation the bond covers, and standing behind the surety financially if performance ever falls short. The bond isn’t a safety net for the principal. It’s a safety net for everyone else, funded by the principal’s promise to pay.
