How to review a subcontractor certificate of insurance

A practical review routine for general contractors, architects, and engineering firms: compare the certificate with the project’s written requirements, request supporting evidence when needed, and keep open questions visible for the right person to resolve.

01 / SET THE REVIEW BASIS

Start with the project’s written requirements.

A certificate can help organize the information supplied for review, but it does not define the project’s insurance requirements. Before checking a subcontractor’s COI, locate the agreement or insurance schedule your firm uses and identify what evidence is still needed.

  1. 01

    Read the project’s written insurance requirements first

    Use the executed agreement, insurance exhibit, or other project document your firm relies on. Note the required policy types, named parties, limits, endorsements, project scope, and relevant dates. Requirements vary by contract and project; do not substitute a generic checklist for the controlling documents.

02 / CHECK THE RECORD

Match names, policy details, and dates.

Review what the certificate actually says, then flag information that is missing, inconsistent, difficult to read, or outside the project’s required window.

  1. 02

    Match the named insured to the subcontracting entity

    Compare the named insured shown on the certificate with the legal entity engaged for the work. If the subcontractor operates through affiliates, joint ventures, or trade names, record the mismatch and ask the producer or insurer to clarify it rather than assuming the names are interchangeable.

  2. 03

    Check each listed policy period against the work window

    Read the effective and expiration dates for each policy line separately. Flag a gap, a date that starts after work is due to begin, or a policy that expires before the relevant work period ends. Ask for updated evidence when dates change; a saved date is not a live confirmation that a policy remains in force.

  3. 04

    Capture the insurer and policy details as shown

    Check that the carrier name, policy number, coverage line, and displayed limits are present and legible where your process requires them. Keep the values tied to the source document and note any unclear or inconsistent entry for follow-up.

03 / COMPARE LIKE WITH LIKE

Compare each coverage line with its own requirement.

Use the written project requirement as the comparison point. This checklist helps a reviewer spot fields to follow up; it does not assess whether insurance is adequate for a particular project.

Policy types

Review prompt

Compare each required line—such as general liability, automobile liability, workers’ compensation, or umbrella/excess liability—against its own row on the certificate. Include only the lines the written project requirements call for.

Limit labels and amounts

Review prompt

Read the amount beside the exact limit label shown. Compare like with like when the project requirement distinguishes a per-occurrence limit, an aggregate, or another measure; do not combine amounts across different policies to fill a gap.

Project or operations description

Review prompt

If the certificate has a project, location, or operations description, treat it as information to compare with the requirement—not as a replacement for policy wording or a determination that the work is covered.

Keep the source visible: record the values as shown on the COI and route an unclear limit, policy term, or project description to a qualified insurance professional. Do not turn an extracted or transcribed value into a coverage decision.

04 / REQUEST SUPPORTING EVIDENCE

Do not infer endorsement status from a certificate box.

If a contract calls for additional-insured status, a waiver of subrogation, or another endorsement, identify the exact requirement and request the corresponding policy document through the subcontractor’s insurance producer or carrier. A certificate holder entry and an endorsement are different records; ask a licensed insurance professional whether the document applies to the named party, work, and period at issue.

JURISDICTION-SPECIFIC REFERENCE

The Texas Department of Insurance explains how Texas certificate rules treat additional-insured and waiver-of-subrogation statements, including when an endorsement is present. Those rules are Texas-specific; use the law and contract requirements that apply to your project.

05 / CLOSE THE LOOP

Record the question and route the next action.

A useful review trail shows what was checked and what still needs a response. Keep the document, the project requirement used for comparison, and the next action together.

  1. 01

    Write down the exact open question

    Name the document field or requirement that does not line up, the source you compared it with, and the date of review. Avoid recording a coverage conclusion when the evidence only shows a mismatch or missing document.

  2. 02

    Request the missing or corrected evidence

    Ask the subcontractor’s authorized insurance producer or carrier for a corrected certificate, applicable endorsement, or other policy information your process requires. Keep the response with the subcontractor’s record and note who reviewed it.

  3. 03

    Route interpretation to the right professional

    Ask a licensed insurance professional about policy terms, whether an endorsement applies, or whether coverage is active. Refer contract language and legal obligations to your attorney. Keep your internal review focused on comparing documents and tracking the follow-up.

06 / KEEP THE BOUNDARY CLEAR

Document tracking is not coverage verification or advice.

Rookbeam can keep submitted documents and human-reviewed details organized. It does not verify whether insurance is active, applicable, or adequate; determine whether a subcontractor satisfies a contract, law, or compliance requirement; or provide legal, insurance, or compliance advice. Your firm remains responsible for its review and decisions. Ask a licensed insurance professional about coverage or policy wording, and consult an attorney about contract language or legal obligations.
