Of everything on a seasonal application, “additional insured” is the phrase that generates the most email. Here is what it actually does.
The short version
Adding someone as an additional insured extends part of your general liability policy to cover them as well, but only for claims tied to your operation on their property. It does not give them a separate policy of their own, and it does not reach anything unrelated to your business.
Why a landowner asks for it
If a visitor is hurt in your maze and sues both you and the property owner, additional insured status positions your policy to respond to the claim against the landowner too. Without it, the landowner is defending that claim through their own farm or commercial policy, which is the outcome they are trying to avoid by asking in the first place.
How to answer it on the application
The application asks whether a landowner or venue already requires the status, and whether you want to supply their exact name and address now or later. Supplying it now saves a step. Waiting until closer to when the certificate is issued is also fine, and there is an option on the form that says so.
Get the legal name right
Certificates are issued to the exact entity named. “Miller Farm” and “Miller Family Farms LLC” are not the same party on a document. Ask the landowner to write out the name and address they want to see, rather than reading it off a mailbox.
What it does not do
It does not make the landowner a partner in your business, it does not cover their property against damage from something other than your operation, and it does not replace their own liability coverage. It is a narrow extension, not a blanket one.
