Primary & Noncontributory Endorsements on COIs

Introduction

If a landlord, general contractor, or client in Texas has ever returned your Certificate of Insurance with the note, “Must be primary & noncontributory,” you are not alone. The request shows up on nearly every construction, real-estate, and service contract today, yet few policyholders—or even some insurance professionals—can explain what it really means. In short, “primary and noncontributory” (P&N) is a promise that your liability policy will respond first, without seeking contribution from the certificate holder’s own insurance. Whether you are a roofer in Round Rock or a ranch owner outside Lubbock, understanding how this phrase affects your coverage—and your pocketbook—can prevent costly project delays and claim disputes.

Why “Primary & Noncontributory” Matters on a Texas COI

Texas is home to more than 3.1 million small businesses, according to the U.S. Small Business Administration, and many of them rely on subcontracting relationships. To keep bids competitive, risk is often shifted downstream through contract insurance requirements. “Primary & noncontributory” is one of the most common of those shifts.

• Primary means your Commercial General Liability (GL) policy pays before any other applicable policy, such as the landlord’s or GC’s.
• Noncontributory means your insurer cannot seek reimbursement from the additional insured’s carrier, even if that other policy covers the same loss. The Texas Department of Insurance (TDI) reminds agents in Bulletin B-0045-13 that a Certificate of Insurance (COI) “does not confer rights and cannot modify coverage.” Only an endorsement issued by the insurer carries legal weight. That distinction is critical: checking the “Yes” box under “Additional Insured” on an ACORD 25 is not enough to satisfy most contract insurance requirements in Texas.

Failing to provide a true primary noncontributory endorsement Texas-style can stall construction draws, delay occupancy permits, or trigger breach-of-contract penalties. We routinely see service providers lose two to three weeks of cash flow because a project owner rejected a COI Texas additional insured line that lacked proper endorsement numbers.

Key Coverage Components and Real-World Examples

1. ACORD 25 vs. The Policy

The ACORD 25 Certificate is only an information snapshot. To activate P&N status, insurers typically issue one of the following:

• CG 20 01 or CG 20 10 for Additional Insured (ongoing operations)
• CG 20 37 for completed operations
• Proprietary endorsements titled “Primary and Non-Contributory Wording” Sample wording you might see: “This insurance is primary and noncontributory with respect to any other insurance available to the additional insured where required by written contract.”

2. Claim Handling Ripple Effect

Consider a plumbing subcontractor in Houston whose faulty weld causes a water loss, damaging the GC’s office trailer. Because the plumber’s policy carries a valid P&N endorsement, the claim is adjusted solely under the plumber’s GL. The GC’s builder’s risk and liability policies stay untouched, preserving their loss ratios and future premiums.

Without the endorsement, the GC’s carrier could demand the plumber’s insurer share costs through subrogation. This almost always leads to longer claim cycles and disputes over defense counsel.

3. Common Pitfalls We See

• Posting a COI that lists “Primary & Non-Contributory” in the Description of Operations but failing to attach the endorsement number referenced in the contract.
• Assuming an “Additional Insured” endorsement automatically grants P&N status; most ISO CG 20 10 editions do not include that language.
• Relying on a blanket P&N endorsement that activates only when “required by written contract” but forgetting to keep signed contracts on file. In an audit, missing paperwork can void coverage.

Case Snapshot: Austin Retail Build-Out

A tenant improvement contractor in Austin lost $18,000 in change-order revenue when the landlord’s risk manager rejected his COI for lacking P&N language. Our agency expedited the correct CG 20 01 plus a carrier-specific P&N endorsement in 36 hours, allowing drywall to resume before the penalty clause kicked in. The tenant opened on schedule, and the contractor kept the relationship intact.

Actionable Insights to Stay Compliant

Know the Contract Language

Before you sign, highlight every insurance clause. If you spot any of these phrases, a P&N endorsement is likely required:

• “Insurance shall be primary and noncontributory.”
• “Additional insured coverage on a primary basis without contribution.”
• “Contractor’s insurance shall respond first.”

Request the Endorsement Early

Carriers vary. Some national markets issue P&N for free; others charge a premium or restrict it to certain industries. Submit requests at least seven business days before the COI due date, especially during peak build season (March–July).

Fast-path checklist to avoid project delays:

• Obtain a copy of the contract section citing insurance wording.
• Email your broker with the project owner’s name, address, and required limits.
• Confirm the endorsement form number that will satisfy the requirement (CG 20 01 04-13, for example).
• Ask for a draft COI plus endorsement before sending to the certificate holder.

Keep Your Records Straight

Texas courts routinely enforce indemnity and insurance clauses as written. Store signed contracts and endorsements for at least five years, matching the statute of repose on most construction defects.

Workarounds When Your Carrier Says “No”

Some surplus lines or farm carriers will not add P&N. Options include:

• Purchasing a project-specific policy with broader wording.
• Negotiating the contract to accept “Primary as respects the named insured only,” a compromise often acceptable for low-hazard trades.
• Securing a hold-harmless agreement in place of insurance modification.

Reference Points for Credibility

• ACORD’s 2023 Certificate of Insurance Resource Guide confirms that the form “does not create or extend coverage.”
• TDI’s Certificate of Insurance statute (Texas Insurance Code §1811) makes it unlawful to issue a COI that misrepresents policy terms. Quoting these sources in negotiations can help educate risk managers who refuse to release retainage without iron-clad phrasing.

Conclusion

“Primary and noncontributory” might look like boilerplate, but it carries real financial consequences for Texas businesses. A single missed endorsement can delay project funding, spark cross-litigation, or drive up future premiums. By understanding the difference between a COI and the policy itself, aligning contract insurance requirements Texas counterparts actually need, and following a proactive request process, you protect your balance sheet and your professional reputation. When in doubt, verify the wording, secure the endorsement, and keep the paperwork on file.
