Excess Liability Insurance (Excess Policy)
Definition
Excess liability insurance adds higher limits above your primary liability policies and pays only after those limits are used up. A pure excess policy usually follows the terms of the policy beneath it and doesn't broaden coverage, unlike an umbrella, which may cover some claims the primary policy doesn't.
In Plain English
Excess policies stack on top of underlying insurance, usually general liability, auto and employers liability. Owners of larger properties, or those with contracts requiring high limits, often build a tower: a primary policy, an umbrella and one or more excess layers.
Most excess policies are Follow Form, meaning they adopt the coverage terms of the policy below. Some add their own exclusions, which can create gaps. Unlike some umbrella insurance forms, a pure excess policy typically won't drop down to cover claims excluded below.
People often use "umbrella" and "excess" interchangeably, but the forms can differ. Read both before assuming they behave the same way.

Example
Hypothetical and simplified: An owner of three apartment communities carries $1 million of primary general liability, a $5 million umbrella and a $5 million excess policy. A severe fire injury claim settles for $8 million. The primary pays $1 million, the umbrella $5 million, and the excess layer may pay the remaining $2 million.
What to Watch For
- Check whether the excess policy follows form or adds its own exclusions.
- Make sure your underlying limits match what the excess policy requires.
- Look for exclusions common on apartments and hotels, such as assault and battery.
- Line up policy periods across all layers to avoid gaps.
Common Questions
What's the difference between excess and umbrella insurance?
Both add limits above your primary policies. An umbrella may also cover some claims the primary excludes, after a retention, while pure excess usually just follows the primary's terms.
How much excess coverage do I need?
There's no single answer. Owners usually weigh lender and contract requirements, how many people are on site and how severe a claim could be.
