What Is an Additional Insured Endorsement?

An additional insured endorsement is a policy amendment that extends insurance coverage to entities other than the primary policyholder. When you add someone as an additional insured to your liability policy, you're essentially sharing your coverage with them for claims that arise from your work or operations.

The Purpose and Benefits

Additional insured endorsements serve several important purposes in business relationships:

• Risk Transfer: They shift certain liability exposures from one party to another.

• Legal Protection: They provide defense coverage for the additional insured.

• Contract Compliance: They satisfy contractual insurance requirements.

• Relationship Management: They facilitate business partnerships by addressing liability concerns.

How Additional Insured Status Works

When a company becomes an additional insured on another's policy, they gain important protections. For example, if a property owner requires a contractor to add them as an additional insured, and someone is injured due to the contractor's work, the property owner can seek coverage under the contractor's policy. This arrangement typically includes:

• Defense coverage (legal representation)

• Indemnification for covered claims

• Protection from certain liability exposures

It's important to note that additional insured status is not the same as being a certificate holder. A certificate merely proves insurance exists, while an additional insured endorsement actually extends coverage rights.

Types of Additional Insured Endorsements

Not all additional insured endorsements are created equal. The specific form used can significantly impact the scope of coverage provided. Understanding these differences is crucial when negotiating contracts and insurance requirements.

Standard ISO Endorsements

The Insurance Services Office (ISO) publishes standardized additional insured endorsements that are widely used in the industry. Common ISO forms include:

• CG 20 10: Covers ongoing operations (but not completed operations)

• CG 20 37: Covers completed operations

• CG 20 26: Designated Person or Organization

• CG 20 33: Automatic Additional Insured for specified relationships

Each form has specific language that defines the extent of coverage provided to the additional insured. For comprehensive protection, many contracts require both the CG 20 10 and CG 20 37 forms to cover both ongoing and completed operations.

Blanket vs. Scheduled Endorsements

Additional insured endorsements generally fall into two categories:

• Scheduled Endorsements: Name specific entities as additional insureds

• Blanket Endorsements: Automatically cover any entity that the named insured has agreed to add via written contract

Blanket endorsements offer convenience for businesses that frequently add additional insureds, as they don't require policy amendments each time. However, they typically contain qualifying language that requires a written contract with specific insurance provisions.

Proprietary Endorsements

Many insurance carriers develop their own proprietary additional insured endorsements. These forms may provide broader or more limited coverage than standard ISO forms. It's essential to review the specific language of these endorsements carefully, as they can vary significantly between insurers.

Step-by-Step: Obtaining and Implementing Additional Insured Endorsements

Implementing additional insured requirements effectively requires attention to detail and proper documentation. Follow these steps to ensure your additional insured endorsements provide the protection you need.

Step 1: Review Contract Requirements

Before requesting or providing additional insured status, carefully review the contract requirements. Pay attention to:

• Specific endorsement forms required (e.g., CG 20 10 07 04)

• Coverage scope (ongoing operations, completed operations, etc.)

• Primary and non-contributory requirements

• Waiver of subrogation provisions

Step 2: Contact Your Insurance Provider

Work with your insurance agent or broker to add the required endorsements to your policy. Be prepared to provide:

• The exact name of the entity to be added

• Contract requirements for specific endorsement forms

• Project details or description of work

Some insurers may charge additional premiums for adding endorsements, particularly for scheduled additional insureds. Blanket endorsements typically involve a one-time charge built into the policy premium.

Step 3: Verify the Endorsement

Once the endorsement is issued, verify that it meets all contractual requirements. Don't simply rely on the certificate of insurance. Request and review the actual endorsement form to confirm:

• The correct entity is named (check spelling and legal entity name)

• The form number matches what was required

• No restrictive language has been added

• The scope of coverage aligns with contract requirements

Step 4: Document and Track

Maintain proper documentation of all additional insured endorsements. This includes:

• Certificates of insurance

• Copies of actual endorsement forms

• Renewal dates and expiration tracking

Using a certificate management system like CoverLedger can streamline this process and ensure you're alerted when endorsements are expiring or need to be renewed.

Best Practices for Managing Additional Insured Requirements

Effectively managing additional insured endorsements requires a strategic approach. These best practices will help you maximize protection while minimizing administrative burden.

Standardize Contract Language

Develop clear, consistent insurance requirement language for your contracts. This should include:

• Specific endorsement forms required

• Coverage scope (ongoing operations, completed operations)

• Primary and non-contributory requirements

• Waiver of subrogation provisions

Consider having an insurance professional or attorney review your standard language to ensure it provides adequate protection.

Implement a Verification Process

Don't just collect certificates—verify the actual endorsements. Establish a process that includes:

• Requesting copies of actual endorsement forms

• Reviewing endorsement language for compliance

• Documenting verification in your tracking system

Use Technology for Tracking

Manual tracking of additional insured endorsements is time-consuming and error-prone. Consider using certificate management software like CoverLedger to:

• Store digital copies of endorsements

• Set up automatic renewal reminders

• Generate compliance reports

• Flag non-compliant endorsements

Consider Risk-Based Requirements

Not all business relationships carry the same risk. Tailor your additional insured requirements based on:

• Project size and complexity

• Potential liability exposure

• Relationship duration

• Industry-specific risks

This approach ensures you're getting appropriate protection without imposing unnecessary requirements on lower-risk relationships.

Common Mistakes to Avoid with Additional Insured Endorsements

Even experienced risk managers can make mistakes when dealing with additional insured endorsements. Here are the most common pitfalls and how to avoid them.

Relying Solely on Certificates

Certificates of insurance (COIs) are not endorsements. They merely evidence that insurance exists but don't modify the policy. Always request and review the actual endorsement forms to verify coverage.

Real-world example: A property owner accepted a COI stating they were an additional insured on a contractor's policy. When a claim occurred, they discovered the endorsement was never issued, leaving them without the expected coverage.

Overlooking Endorsement Limitations

Many additional insured endorsements contain limitations that can significantly restrict coverage. Watch for:

• "Caused, in whole or in part" language

• Scope limitations (e.g., only covering ongoing operations)

• Coverage restricted to the minimum required by contract

• Exclusions for the additional insured's sole negligence

Neglecting to Specify Form Edition Dates

ISO regularly updates its endorsement forms, and newer editions often provide more limited coverage. For example, the CG 20 10 04 13 is more restrictive than the CG 20 10 11 85. When possible, specify the edition date in your requirements.

Failing to Address Primary/Non-Contributory Status

Without primary and non-contributory wording, an additional insured's own insurance might have to contribute to a claim before the named insured's policy responds. This undermines the risk transfer intent of the additional insured requirement.

Inadequate Tracking Systems

Many organizations fail to implement robust tracking systems for additional insured endorsements. This can lead to expired coverage, non-compliance with contractual requirements, and unexpected liability exposure.

Key Takeaways About Additional Insured Endorsements

• Additional insured endorsements extend policy coverage to entities beyond the named insured, providing crucial protection in business relationships.

• The specific endorsement form matters—different forms provide different levels of protection and coverage scope.

• Always verify actual endorsements rather than relying solely on certificates of insurance.

• Implement systematic tracking of endorsements to ensure continuous compliance and protection.

• Consider technology solutions like CoverLedger to automate and streamline the management of additional insured requirements.

Frequently Asked Questions About Additional Insured Endorsements

What's the difference between a certificate holder and an additional insured?

A certificate holder simply receives proof that insurance exists through a Certificate of Insurance (COI). They have no rights under the policy. An additional insured, by contrast, is actually added to the policy via an endorsement and receives coverage benefits, including defense and indemnification for covered claims arising from the named insured's work or operations.

How much does it cost to add an additional insured to a policy?

The cost varies by insurer and policy type. Many policies include blanket additional insured endorsements for no additional per-entity charge (though the base premium may be higher). For scheduled endorsements, the cost typically ranges from $50 to $500 per additional insured, depending on the policy type, coverage limits, and risk exposure. Some insurers offer packages with unlimited additional insureds for a flat fee.

Can an additional insured file a claim directly with the insurer?

Yes, an additional insured can file a claim directly with the insurer when they face a liability claim that potentially falls under the coverage provided by the additional insured endorsement. The insurer will evaluate the claim based on the policy terms and the specific language in the endorsement. However, the named insured should typically be notified as well, as the claim may affect their loss history and future premiums.

What's the difference between ongoing operations and completed operations coverage?

Ongoing operations coverage protects additional insureds for claims arising while the named insured is actively performing work. Completed operations coverage extends protection after the work is finished. For example, if a contractor installs a staircase that collapses two years later, completed operations coverage would be needed to protect the property owner as an additional insured. Many standard endorsements (like the CG 20 10) only cover ongoing operations, which is why contracts often require both CG 20 10 and CG 20 37 endorsements.

Do additional insured endorsements increase the policy limits?

No, additional insured endorsements do not increase the overall policy limits. The limits are shared between the named insured and all additional insureds. This means that if multiple parties make claims against the policy, the total coverage available could be depleted. For high-value projects or relationships with significant liability exposure, consider requiring higher limits to ensure adequate coverage for all parties.

Conclusion: Mastering Additional Insured Endorsements

Additional insured endorsements are a critical component of risk management and insurance compliance in business relationships. By understanding the different types of endorsements, implementing best practices for verification and tracking, and avoiding common pitfalls, you can ensure your organization is properly protected.

Remember that effective management of additional insured requirements goes beyond simply collecting certificates of insurance. It requires attention to detail, systematic processes, and ongoing monitoring. With the right approach and tools, you can transform insurance compliance from a administrative burden into a strategic advantage that protects your business relationships and bottom line.
