Follow Form (Following Form)
Definition
Follow form means an excess or umbrella policy adopts the same terms, conditions and exclusions as the policy beneath it. A follow-form excess policy generally covers a claim only if the underlying policy covers it, which helps keep coverage consistent from layer to layer.
In Plain English
In a tower of liability coverage, each layer should line up. A follow-form excess policy says, in effect, "we cover what the policy below covers, above its limit." That lowers the chance of a gap where one layer pays and the next doesn't.
Few policies are pure follow form. Many add their own exclusions or conditions while following the rest. Those added exclusions are where the excess layer differs from the underlying insurance.
An umbrella insurance policy may follow form for some coverages and be broader or narrower for others. When reviewing a liability program, ask for a side-by-side comparison of the underlying and excess forms.

Example
Hypothetical and simplified: A hotel's primary general liability policy covers assault and battery claims, but its excess policy adds an assault and battery exclusion. A $3 million claim from an assault on the property would be covered only up to the primary limit, even though the owner bought a $5 million excess policy.
What to Watch For
- Ask whether the excess policy follows form, and get a list of any exceptions.
- Compare the exclusions in each layer with the primary policy.
- Check that limits and policy periods line up across layers.
- Review again when the primary policy changes at renewal.
