Your car and home policies each have a liability limit, the most they will pay if you are sued for an injury or damage you caused. If a judgment or settlement runs past that limit, the rest can come out of your own savings and assets. An umbrella is a separate policy that adds another layer on top, often $1 million or more, and can add defense costs and a few kinds of claims the policies underneath leave out. Insurers expect your underlying limits to be at a set level before they will write one.
How an umbrella works
An umbrella kicks in when you reach the limit on the underlying liability coverage in an auto, homeowners, renters or co-op and condo policy, and it pays only after that coverage is exhausted. According to the NAIC, it covers situations you are held responsible for, including bodily injury, property damage and personal injury, and it can pay liability and legal defense costs above what your primary policy pays.
Picture a serious car accident where the claim is larger than your auto liability limit. The auto policy pays to its limit first. The umbrella is built to respond to the amount above that, up to its own limit. A common umbrella adds $1 million or more on top of the policies underneath.
What it can cover that home and auto don’t
An umbrella is more than a higher limit. It may cover some liability claims your primary policies don’t, and the Insurance Information Institute points to libel and slander as examples, while New Jersey’s insurance department adds defamation of character. Whether a particular claim is covered depends on the policy’s wording, so I read the personal injury definition and the exclusions before you choose one.
What it does not do is just as important:
- Your own property. An umbrella will not pay for damage to your home or vehicle. If your auto policy doesn’t cover hail damage to your car, the umbrella won’t either.
- Punitive damages. The NAIC lists punitive damages, for example after drunk driving, among what umbrella policies won’t pay.
The underlying limits you need first
An umbrella assumes the policies under it carry real limits. Most insurers want about $250,000 of liability on your auto policy and $300,000 on your homeowners policy before they will sell you an umbrella, according to the Insurance Information Institute. Each company sets its own schedule, so I get it in writing before we pick limits.
That means buying an umbrella often starts with raising the limits on your auto insurance and home policy. Read the umbrella’s requirement for keeping that underlying insurance in force, and tell me before you change or drop any policy underneath it.
Who usually buys one
New Jersey’s insurance department describes umbrella insurance as something for people concerned about exposed personal assets, and says it may not be for everyone. The Insurance Information Institute names the lifestyle risks that tend to draw lawsuits:
- A pool, especially if you host pool parties.
- Rental property you own and rent out to others.
- A teenage driver in the household.
- A dog.
To that list I add homeowners with real equity and anyone whose income would be the target of a judgment. Underwriters will ask about every driver, every property, any watercraft and your claims history. If your main concern is liability at home, personal liability insurance explains what the homeowners layer itself does.
Personal umbrella vs. commercial umbrella vs. excess
A commercial umbrella does the same job for a business. It generally sits over the business auto policy, the commercial general liability policy and employers liability, and can also extend over other liability coverage a company carries. Under IRMI’s definition, an umbrella provides excess limits when the underlying limits are exhausted, can drop down when an underlying aggregate limit is used up, and can cover some claims the underlying policies don’t, subject to a self-insured retention.
An excess liability policy is narrower. It provides limits above an underlying policy, often an umbrella, and is no broader than the policy beneath it: its only purpose is more limit. If you own a business, the umbrella built for it is a commercial umbrella over the business’s own policies; start with general liability and commercial auto.
Common questions
Does an umbrella cover damage to my own car or house?
No. Umbrella policies pay liability claims against you, not damage to your own home or vehicle.
What underlying limits do I need?
It depends on the insurer. The Insurance Information Institute says most want about $250,000 of auto liability and $300,000 of homeowners liability before they will sell an umbrella.
Does an umbrella cover libel or slander?
Some personal umbrellas are designed to respond to claims like libel and slander that home and auto policies may leave out. The policy’s personal injury definition and exclusions decide it.
Is an umbrella the same as excess liability?
No. An excess policy only adds limits and is no broader than the policy under it, while an umbrella can also respond to some claims the underlying policies don’t cover.
Will a personal umbrella cover my business?
Don’t count on it. A business needs its own liability policies, and a commercial umbrella is the layer built to sit over business auto, general liability and employers liability.
