An endorsement is a document attached to a policy that changes it. It can add coverage, restrict it, add a party, or alter a condition. Where an endorsement conflicts with the base policy form, the endorsement governs. This is why reading the declarations and the base form alone gives an incomplete and sometimes misleading picture of what is actually covered.

Why brokers care
Most of what matters at renewal lives in the endorsements rather than the declarations page. A limit can look unchanged while an endorsement three pages later restricts it for a particular exposure. Nobody reads a seventy page wording line by line during renewal season, which is precisely why the differences that matter are the ones that go unnoticed until a claim.
What to check
- The full endorsement schedule, not just the declarations
- Any endorsement added or removed since the expiring term
- Whether an endorsement restricts a limit that appears intact on its face
- That every endorsement the contract requires is actually attached
- Effective dates, since endorsements are often mid-term
Common mistake
Reading the declarations page and stopping there. The declarations list what exists. The endorsements decide what it does, and a limit that looks intact on the dec page can be materially narrowed three pages into the schedule.
How this produces claims is covered in the E&O exposure guide.
