Before you decide
- An umbrella is additional liability cover, not building repair cover.
- Confirm that every entity and rental activity is accepted.
- A missing primary limit can leave an owner-funded gap.
Start below the umbrella
Liberty Mutual describes a personal umbrella as additional liability protection above underlying policies. Its explanation also flags business activity limitations. An entity-owned rental portfolio needs an express underwriting and policy answer; personal umbrella marketing is not proof of commercial rental acceptance.
Collect the underlying declarations, liability limits, insured names, locations and effective dates. Ask the umbrella provider to identify the required underlying schedule and any minimum limits. Confirm whether other insurers’ primary policies are acceptable.
Draw the attachment
Illustrative structure: primary liability of $1 million and an additional layer attaching above $1 million. If the primary policy actually provides only $500,000 for the relevant claim, the remaining $500,000 before attachment may be an owner exposure unless the contracts provide otherwise. The second policy should not be assumed to drop down.
This diagram in words is not a claim payment forecast. Coverage, defense expenses, exhaustion language and retentions can change how the layers respond. Ask the partner to explain the same scenario using the actual forms.
Use an attachment checklist
| Item | Evidence |
|---|---|
| Named insured | Legal owner, operating entities and accepted persons |
| Underlying schedule | Policy number, insurer, activity, limit and dates |
| Attachment and exhaustion | Amount and acceptable method of exhausting the primary |
| Defense | Who controls defense and whether costs reduce limits |
| Exclusions | Operations or allegations not carried into the upper layer |
| Notice | Who receives claims and when both insurers must be notified |
Keep the schedule current
Adding a property to a primary policy may not automatically add it to the umbrella. Route acquisitions, ownership changes, guest stays and management activities through both reviews. Retain the written confirmation.
Do not select a limit simply because it equals net worth or a lender minimum. Discuss credible loss severity, concentration, contracts, available structures and affordability with the licensed partner. The useful output is an accepted schedule and clear retained exposure, rather than the largest number on a summary sheet.
