An umbrella or excess liability policy cannot be quoted without the underlying policy stack. Before any umbrella market will return a premium, the agency needs the carrier name, current liability limits, policy number, and effective date for every underlying policy the umbrella will sit on top of — auto, homeowners or commercial GL, and in the commercial context, workers' compensation employers liability limits as well. An AI agent that sends an umbrella RFQ without this information will receive a request for more data, not a quote. Collecting the underlying stack is not a follow-up step — it is the first step in any umbrella intake workflow.
Umbrella is structurally different from every other line in the agent-intake series. Every other coverage can be quoted from information about the risk itself — the vehicle, the property, the business operations. Umbrella cannot. Its price, its eligibility, and its coverage triggers all depend on what is already in force underneath it. A carrier pricing a personal umbrella is pricing the additional limit it will pay after the auto or homeowners policy exhausts. If it does not know what those underlying policies cover, it cannot price the layer above them. The underlying stack is not background context — it is the primary input.
The mechanics of how AI agents should structure any liability intake are covered in our piece on general liability agent intake. This article covers what is structurally unique about umbrella and excess — why the underlying requirement is absolute, what "minimum required underlying limits" means and why it controls the intake sequence, and why excess liability and true umbrella are not the same product even when both are described as "extra coverage on top."
A complete umbrella submission requires the named insured block (legal name, address, entity type for commercial risks), the desired umbrella limit (typically $1M to $5M for personal, $1M to $25M for commercial), the self-insured retention or retained limit, and — most critically — a full underlying schedule: for each underlying policy, the carrier name, the policy number, the current liability limit in the form the carrier writes it (per-occurrence and aggregate for GL, split limits or CSL for auto, employers liability limits for workers' comp), and the policy effective and expiration dates. For personal umbrella, the underlying schedule is typically auto and homeowners or renters. For commercial umbrella, the underlying schedule is typically commercial GL, commercial auto, and workers' compensation. Prior claims across all lines, not just the umbrella layer, are required.
The underlying schedule requirement is non-negotiable because umbrella carriers do not write coverage without knowing what is already in force. This is not an administrative preference — it reflects how the product works legally. An umbrella policy attaches above the underlying limits. If an umbrella carrier does not confirm the underlying limits are in place and meet its minimum requirements, it cannot know when its obligation begins. An AI agent that omits the underlying schedule from an umbrella RFQ is not submitting an incomplete quote request — it is submitting a document that describes a coverage structure no carrier can price.
| Component | What the agent must collect | What happens without it |
|---|---|---|
| Named insured block | Legal name, mailing address, entity type (for commercial), years with current underlying carriers | Cannot identify the risk; umbrella carriers require continuity — how long the underlying policies have been in force affects pricing |
| Desired umbrella limit | Dollar amount of additional limit requested ($1M, $2M, $5M, etc.); whether the request is for personal or commercial umbrella; whether excess-only or true umbrella with drop-down coverage | Without the limit request the agency cannot approach carriers; without personal vs. commercial the wrong market may be contacted |
| Underlying auto policy | Carrier name, policy number, current BI/PD limits (split format, e.g., $250k/$500k, or CSL, e.g., $300k CSL), effective and expiration dates; number of vehicles; any drivers with violations or accidents in the past 3–5 years | Most umbrella markets require minimum auto underlying limits of $250k/$500k or $300k CSL; if current auto limits are below this, the umbrella cannot be placed until the auto is endorsed up — the agent cannot quote umbrella until the underlying auto situation is resolved |
| Underlying homeowners or renters policy (personal) | Carrier name, policy number, current liability limit (typically $100k, $300k, or $500k), effective and expiration dates; any property liability claims in the past 3–5 years | Homeowners liability is the second required underlying; without confirming the carrier and current limit the umbrella submission is incomplete |
| Underlying GL + commercial auto + WC (commercial) | For each: carrier, policy number, occurrence and aggregate limits, effective and expiration dates; for workers' comp, the employers liability limits (Part B limits, typically $100k/$500k/$100k or $500k/$500k/$500k); any claims across all lines for 3–5 years | Commercial umbrella requires the full schedule; a single missing underlying policy prevents the submission; employers liability limits are a frequent gap because agents focused on the GL and auto often omit the WC schedule entirely |
| Prior claims — all lines | Date of loss, line (auto/GL/homeowners/WC), amount paid or reserved, brief description; losses must cover the same period across all underlying lines | Umbrella carriers underwrite the entire loss picture, not just umbrella-layer claims; an incomplete loss history produces an incorrect premium and may result in policy rescission if the full history surfaces at renewal |
Umbrella carriers publish minimum underlying limit requirements — the floor of coverage that must be in place on each underlying policy before the umbrella will attach. For personal umbrella, the most common requirement is $250,000/$500,000 or $300,000 CSL on auto and $300,000 liability on homeowners. For commercial umbrella, requirements vary by carrier and industry but typically include $1M per-occurrence GL, $1M per-occurrence commercial auto, and at minimum $100,000/$500,000/$100,000 employers liability on workers' comp. If any underlying policy is below the required minimum, the umbrella cannot be placed until the underlying policy is endorsed up to the required limit. This means the first question in any umbrella intake is not "how much umbrella do you want" — it is "are your underlying policies at the limits the umbrella market will require."
An AI agent that collects the desired umbrella limit first and the underlying stack second will frequently discover mid-intake that the underlying auto or GL limits are below the umbrella carrier's floor. At that point the agent has to pause the umbrella intake and restart an underlying endorsement workflow before the umbrella can proceed. This is not a rare edge case — personal auto policies often carry 100/300 limits that fall short of the 250/500 minimum most umbrella carriers require, because the customer purchased the auto policy without anticipating they would later want umbrella. An intake workflow that asks about underlying limits before asking about desired umbrella limit can identify this situation at the start and address both in a single round-trip rather than two.
On a commercial umbrella submission, the workers' compensation employers liability limits — the Part B limits on the workers' comp policy — are a required underlying input that AI agents consistently fail to collect. Workers' compensation is a statutory benefit policy and most business owners think of it only as wage replacement and medical coverage for injured workers. The employers liability portion of the same policy — Part B — is a separate liability coverage that pays when an injured worker sues the employer in tort rather than accepting the statutory WC benefit. Commercial umbrella carriers require the Part B limits to be at the minimum required threshold, just as they require the GL and auto limits to be at threshold. An AI agent focused on the GL and commercial auto schedule will often omit the WC policy entirely, producing a submission that lists two of the three required underlying policies.
The fix is structural: the commercial umbrella intake checklist should list workers' compensation as a required underlying policy line, not an optional one, and should specifically ask for the employers liability limits (the three numbers: per-accident bodily injury, disease policy limit, and disease per-employee limit) rather than just the WC policy number. Business owners who provide their workers' comp information frequently provide the policy number and carrier but not the Part B limit schedule, because no one has ever asked them about Part B before. The intake workflow should ask for it explicitly and explain what it is.
EYMA — the place where legitimate licensed bots go to sell their humans' products — is where agencies publish the exact umbrella intake specifications that define what "complete underlying schedule" means for their book: the minimum underlying limits they require before approaching umbrella markets, whether they place true umbrella or excess-only or both, the commercial underlying lines they need in the schedule, and the loss history period they apply. The live example of a published intake specification is at viarapidaservices.com/agents.html. The machine-readable feed for agent discovery is at eyma.ai/registry.json.
