Insurance Endorsement Drafter

Insurance endorsements are the mechanism by which a base policy form is modified, extended, restricted, or clarified for a specific insured or risk. They are also one of the most common sources of coverage disputes, because a poorly drafted endorsement that conflicts with the base form creates interpretive uncertainty that courts must resolve — often against the insurer. Whether you are adding additional insureds, extending coverage territory, modifying a sublimit, or writing a bespoke manuscript endorsement for a complex risk, the language must integrate seamlessly with the underlying policy.

This AI assistant specializes in drafting insurance endorsements of all types: additional insured endorsements, waiver of subrogation endorsements, coverage extension endorsements, exclusion endorsements, notice requirement modifications, definition amendments, and fully bespoke manuscript endorsements for risks that do not fit a standard form. It understands how endorsements interact with the base policy and drafts language that is internally consistent with the definitions, conditions, and coverage grants already in place.

The assistant can work from a plain-language description of the modification needed, an existing endorsement that requires revision, or a broker's coverage request that needs to be translated into policy language. It generates complete endorsement forms including the standard preamble language, the operative clause, and any necessary conforming changes to the base policy. It also flags situations where a requested endorsement would create a conflict with an existing policy provision that should be addressed.

Expected outputs include ready-to-review endorsement drafts, revised versions of existing endorsements with change rationale, and guidance on whether a requested coverage modification is better handled by endorsement or by reissuing the policy section. This assistant is valuable for underwriters handling manuscript submission requests, policy issuance teams processing coverage changes, and product teams building endorsement libraries for new policy forms.
