Bonding for  Construction Attorneys 

Surety Bonds Touch Every Part of Construction Law

If you practice construction law, surety bonds are woven into your work whether you specialize in them or not. They appear in contract negotiations, bid protests, project defaults, subcontractor payment disputes, and claims resolution. Understanding how bonds work, who the parties are, what triggers a claim, and how the surety responds gives you a significant advantage when advising contractor clients.

Most construction attorneys understand bonds at a general level. But the specifics of how the surety relationship works, what the General Agreement of Indemnity means for your client, how bond claims are investigated and resolved, and how bonding requirements intersect with contract language are areas where deeper knowledge pays off.

At Grit Insurance Group, we work with construction attorneys as part of the professional team that supports our contractor clients. When a bond claim arises, when contract language raises bonding questions, or when a contractor needs legal advice on their surety obligations, having an attorney who understands the surety framework makes the process smoother for everyone. This page explains how surety bonding works from the attorney's perspective.

 How Surety Bonds Work (A Quick Primer for Attorneys)

A surety bond is a three-party contract. The contractor (principal) is obligated to perform. The project owner (obligee) is the party protected by the bond. The surety company is the guarantor that stands behind the contractor's obligation.

There are three primary types of contract surety bonds. A bid bond guarantees that the contractor's bid is submitted in good faith and that they will enter into the contract and provide the required performance and payment bonds if awarded the project. A performance bond guarantees that the contractor will complete the project according to the contract terms. A payment bond guarantees that the contractor will pay subcontractors, laborers, and material suppliers.

The legal foundation for bonding on federal projects is the Miller Act, which requires performance and payment bonds on federal construction contracts exceeding $150,000. Every state has its own version, commonly called a Little Miller Act, that applies bonding requirements to state and local public projects. Thresholds and specific requirements vary by jurisdiction.

The critical legal distinction between surety bonds and insurance is that the surety does not expect losses. The bond is a guarantee of the contractor's performance, not a risk transfer mechanism. If the surety pays a claim, the contractor is obligated to reimburse the surety in full under the General Agreement of Indemnity.

The General Agreement of Indemnity

The GAI is the foundational legal document in the surety relationship, and it is one of the areas where your contractor clients most need legal counsel. The GAI is signed when the bond program is established and applies to every bond issued under the program.

Under the GAI, the contractor and all individual indemnitors (typically every owner with significant equity) personally guarantee to reimburse the surety for any losses, costs, and expenses the surety incurs as a result of issuing bonds on the contractor's behalf. This includes claim payments, investigation costs, legal fees, and completion costs if the surety has to step in and finish a project.

The GAI creates joint and several liability among the indemnitors. It typically includes broad collateral provisions that allow the surety to demand collateral when it believes a loss is likely. It may also include provisions granting the surety assignment of the contractor's rights under the construction contract.

Many contractors sign the GAI without fully understanding the personal exposure it creates. As their attorney, helping them understand the scope of the indemnity obligation before they sign is a high-value service. It does not mean they should avoid bonding. It means they should enter the relationship with eyes open and manage their bond program in a way that minimizes the risk of a claim.

Bond Claims: How They Work

When a bond claim is filed, the surety initiates an investigation to determine whether the claim is valid and what the appropriate response is. The process differs depending on the type of bond.

Performance bond claims. A performance bond claim is typically filed by the project owner when the contractor has defaulted or is at serious risk of default. The surety investigates the circumstances and generally has several options: arrange for the contractor to cure the default and complete the work, finance a replacement contractor to complete the project, negotiate a settlement with the obligee, or deny the claim if the investigation determines it is not valid. The surety's obligation under the performance bond is to ensure the project is completed, not simply to pay the obligee the bond amount. This distinction matters in how claims are resolved.

Payment bond claims. A payment bond claim is filed by a subcontractor, laborer, or material supplier who has not been paid by the contractor. On public projects, the payment bond is the claimant's primary remedy because they cannot file a mechanics' lien against government property. Payment bond claims typically have strict notice and timing requirements that vary by jurisdiction and by whether the project is federal (governed by the Miller Act) or state/local (governed by the applicable Little Miller Act). Missing a notice deadline can extinguish the claim.

Bid bond claims. Bid bond claims arise when a contractor wins a bid and then fails to enter into the contract or provide the required performance and payment bonds. The surety's exposure is typically limited to the difference between the contractor's bid and the next lowest qualified bid, up to the bid bond amount.

As a construction attorney, you may be involved in bond claims on either side: representing the contractor who is the subject of the claim, representing a subcontractor filing a payment bond claim, or representing a project owner filing a performance bond claim. Understanding the surety's investigation process and the legal framework governing the specific bond type is essential to effective representation.

Bonding Requirements in Construction Contracts

When you are reviewing or drafting construction contracts for your contractor clients, bonding requirements are a standard provision that deserves careful attention.

Contract bonding provisions typically specify the types of bonds required (bid, performance, payment), the bond amounts (usually 100% of the contract value for performance and payment bonds), the rating requirements for the surety company (commonly an A.M. Best rating of A- or better, and inclusion on the U.S. Treasury's Circular 570 list of approved sureties), and the timeline for providing bond evidence after contract award.

As the attorney, there are several areas where your review adds value. Make sure the bonding requirements are clear and achievable for your client. If the contract requires a bond amount or surety rating that your client's current program cannot meet, flag it early so they can work with their bond agent to address it before the bid deadline. Review the contract's default provisions to understand what triggers a performance bond claim and what cure rights the contractor has before the obligee can declare default. Examine the payment terms and retainage provisions, because slow payment from the owner can create cash flow problems that lead to payment bond claims even when the contractor is performing well.

If your contractor clients do not have a bond agent, or if their current agent is not proactive about contract review, connecting them with a bonding advisor who can evaluate these provisions alongside you is a valuable referral.

Bid Protests and Bonding

Bid protests on public projects frequently involve bonding issues. A competing contractor may protest a bid award on the grounds that the winning bidder did not submit a compliant bid bond, that the bid bond was from a surety not authorized to do business in the jurisdiction, or that the bid bond amount did not meet the solicitation requirements.

On the other side, your contractor client may need to defend against a bid protest where the protesting party challenges their bid bond compliance. Understanding the specific bid bond requirements in the solicitation and the applicable procurement regulations is essential in these situations.

How the Attorney Fits Into the Contractor's Professional Team

The strongest bond programs are supported by a team of professional advisors working together: a bond agent, a CPA, a banker, a fractional CFO (when applicable), and a construction attorney.

Your role as the attorney touches the bonding relationship in several ways. Reviewing the GAI before your client signs it. Advising on contract provisions that affect bonding. Representing your client in bond claims, bid protests, and disputes. Helping structure buy-sell agreements and perpetuation plans that the surety reviews as part of the underwriting process. And advising on entity structure and ownership changes that can affect who signs the indemnity agreement.

At Grit, we regularly coordinate with our clients' attorneys when legal issues intersect with the bonding program. When a contract has unusual bonding provisions, when a claim is filed, or when a client is restructuring their business, having an attorney and a bond agent who communicate directly produces better outcomes for the contractor.
