Types of Surety Bonds Explained

Nearly every surety bond fits into one of four families, sorted by what it guarantees and who it protects. Here is the map: the four types, what each one does, and where your bond fits, with links to the specific bonds we place.

One structure, four jobs

Every surety bond is the same three-party promise: you (the principal) will meet an obligation to a obligee, and a surety guarantees it. What separates the types is the obligation itself. Sort by that, and the whole surety world falls into four families.

FamilyGuaranteesWho requires it
ContractA construction project is bid, built, and paidProject owners and public agencies
License & permitA business follows the laws of its tradeState and local licensing agencies
Court & probateA duty in litigation or an estate is metCourts
FidelityAgainst employee theft or dishonestyEmployers (and some clients)

1. Contract (construction) bonds

Contract bonds guarantee a construction project. They travel in a set: a bid bond backs your proposal, a performance bond guarantees you finish the work, and a payment bond guarantees your subcontractors and suppliers get paid. Public works almost always require them. See the contract bonds hub for how they fit together.

2. License and permit bonds

These let a business get and keep a license by guaranteeing it will follow the rules of its trade. The California contractor license bond is the headline example, but the family is huge: notary, auto dealer, freight broker, cannabis, and dozens of other commercial and permit bonds. They are the most common bonds because so many trades require one to operate.

3. Court and probate bonds

Court bonds back a duty inside the legal system. Judicial bonds like an appeal bond come up in litigation, while probate and fiduciary bonds like a probate bond or guardianship bondguarantee that an executor, administrator, or guardian handles an estate or a person's affairs honestly.

4. Fidelity bonds

Fidelity bonds protect a business from its own people: theft, embezzlement, or fraud by an employee. A fidelity (employee dishonesty) bond covers general staff, and an ERISA bond is the federally required version protecting a retirement plan. Strictly, fidelity bonds are insurance-like coverage, but they are placed through the same surety markets.

Which one do you need?

You rarely choose. The obligee, the agency, court, or owner requiring the bond, names it in a statute or on a bond form. Your job is to read that requirement; ours is to place the exact bond fast and at the best rate. Not sure which family you are in? The glossary defines the terms, and a quote gets you the specific bond identified and priced.

Questions

FAQs

Reviewed by Michael Melshenker, CEO. Updated June 2026.

What are the main types of surety bonds?
Most surety bonds fall into four families: contract (construction) bonds, license and permit bonds, court and probate bonds, and fidelity bonds. Each guarantees a different obligation to a different protected party.
What is the most common surety bond?
For businesses, the license and permit bond is the most common, because so many trades and professions must post one to get licensed. In California, the $25,000 contractor license bond is the classic example.
Are all surety bonds three-party agreements?
Yes. Every surety bond involves the principal (you), the obligee (the party you must perform for), and the surety (the company that backs you). What changes across bond types is the obligation being guaranteed.
How do I know which surety bond I need?
The party requiring the bond, an agency, a court, or a project owner, names it, usually on a form or in a statute. Tell us that requirement and we place the exact bond. When in doubt, start with a quote and we will identify it.
