What is a manuscript endorsement?
A manuscript endorsement is non-standard policy language — drafted by the carrier (or sometimes the broker) for a specific account, rather than a filed ISO/AAIS form with a known meaning. Because it doesn't map to a form library, it can't be judged mechanically: two manuscript endorsements with similar titles can do completely different things.
That's exactly why they're the highest-risk item on any renewal and the one place automated checking should defer to a human.
Why manuscript endorsements are high-risk at renewal
A manuscript endorsement can add an exclusion, carve back a grant of coverage, change a definition, or impose a condition — in bespoke wording that looks unremarkable in a form schedule. A renewal that introduces a new manuscript endorsement, or changes an existing one, can materially alter coverage without touching a single limit on the dec page.
Standard vs. manuscript, and why the distinction matters
A standard ISO/AAIS form is identifiable by number and edition, with a known purpose you can compare year over year. A manuscript endorsement has no such anchor — so the right treatment is to detect it, flag it, and put it in front of a person who reads the actual language. Pretending a machine 'understands' bespoke wording is how coverage surprises happen.
How human-in-the-loop checking handles them
BindCheck diffs the standard forms and dec-page numbers deterministically, and when it encounters a manuscript or non-standard endorsement it flags it for your review rather than guessing — surfacing that the renewal added, removed or changed a manuscript item so a human reads it against the account's needs. The routine comparison is automated; the judgment on bespoke language stays with the agent.
Frequently asked questions
How can I tell a manuscript endorsement from a standard one?
Standard forms carry a filed number and edition date and a known purpose; manuscript endorsements typically have carrier-specific titles or numbers and unique wording. When a form doesn't map to the standard library, treat it as manuscript and read it directly.
Why not let AI just interpret the manuscript language?
Bespoke wording is precisely where automated interpretation is least reliable and the stakes are highest. Flagging it for human review — rather than auto-scoring it — is the safer, more defensible design.
