ACORD 131: Umbrella and Excess Section Explained

ACORD 131 is the Umbrella / Excess Section used to organize information an insurer needs to evaluate an umbrella or excess liability application. It brings the layer together with underlying liability policies, locations, vehicles, and exposures that may affect underwriting. It is an application section, not a coverage grant, binder, certificate, or proof that an insurer accepted the risk.

What is ACORD 131 used for?

ACORD 131 is the line-specific application section for a commercial umbrella or excess submission. Vertafore's current form map calls it the Umbrella / Excess Section and places it among the forms that make up a commercial umbrella application.^[1] A separate Vertafore release note identifies the 2017/11 edition as a version that attaches to ACORD 125 for documentation purposes.^[2]

The form helps an underwriter compare the proposed layer with the policies beneath it. The final policy determines the contract design, exclusions, attachment terms, and defense provisions.

What information does ACORD 131 collect?

The section groups requested coverage information with the insured's underlying program and exposure schedules. Vertafore maps data into areas for umbrella limits and premiums, primary locations and subsidiaries, underlying liability policies, vehicles, underlying general liability information, and additional exposures.^[1] Its map uses business auto liability as an underlying-policy example.

Why are the underlying policies important?

The underlying schedule tells the umbrella or excess underwriter what insurance is expected to respond before the proposed layer. Use current carrier names, policy numbers, effective dates, limits, and relevant coverage details from binders or declarations. Do not copy the schedule from an old application without checking renewals, replacements, reduced limits, or canceled policies.

The schedule is still only application data. The issued policy may have its own underlying schedule and required limits. Compare it with the underlying policies after binding because the insurer's documents control how the layers interact. For broader product context, see umbrella versus excess liability insurance.

Does ACORD 131 prove umbrella or excess coverage is bound?

No. ACORD 131 records application information and a requested insurance structure. The California Department of Insurance defines a binder as a temporary or preliminary agreement that provides coverage until the policy is written or delivered.^[3] An application section is not that agreement unless an authorized insurer separately issues or adopts a binder under applicable rules.

Look for written evidence from the insurer or its authorized representative. The binder or declarations should identify the insurer, named insured, effective dates, limits, and applicable forms or conditions. ACORD also states that it is not an insurance company and does not provide coverage, which is why the ACORD name on an application cannot establish that any insurer accepted it.^[4]

Where can you get the official ACORD 131 form?

Eligible users can search and download current forms through the logged-in ACORD Forms Portal.^[5] Keep the signed application and every overflow schedule. This page does not reproduce ACORD's wording or layout.

The Bottom Line

ACORD 131 organizes an umbrella or excess application around the underlying policies and exposures. Reconcile each schedule with current records. Look to the insurer's binder and issued policy, not the application, for proof of coverage and controlling terms.
