CG 20 26 is an additional insured endorsement used to schedule a designated person or organization. Venue and landlord requirements often mean this form when they name one specific additional insured. It does not replace CG 20 10 or CG 20 37.
Who the form is for
CG 20 26 schedules a named person or organization as an additional insured. Landlords use it when the tenant's policy must name the landlord. Venues use it when the client's or the vendor's policy must name the venue for an event. The job of the form is to designate that party. It is not a general statement that additional insured status exists somewhere in the program.
Event files should point at the event venue workflow. The venue's legal name has to match the schedule. A holder line with the venue's name is still only the holder. The endorsement is what the requirement is usually asking for when it says the venue must be an additional insured. Additional insured versus certificate holder is the distinction to keep on the file.
What it does not replace
CG 20 26 does not replace CG 20 10. Ongoing operations on a construction contract can still require CG 20 10 even if a landlord is also scheduled on CG 20 26. CG 20 26 does not replace CG 20 37. Completed operations remain a separate form when the contract names them. A venue agreement can require CG 20 26 for the event and still be silent on completed operations. Read the agreement. Do not add a form it does not require, and do not drop a form it does.
It also does not replace liquor liability additional insured status when alcohol will be served. A general liability additional insured form is not a liquor liability form. If the event agreement names liquor, collect that endorsement as its own requirement. Primary and noncontributory wording is a further sentence, not a synonym for CG 20 26.
Names, dates, and the event window
Compare the scheduled name to the contract. Venue, landlord, owner, and manager are often different legal entities. A schedule that names the venue brand and not the entity can be a gap. Dates matter because the event, including setup and teardown, has to fall inside the policy period. CG 20 26 does not extend a policy that expires before load-out. Keep the dates on the vendor file next to the form.
A blanket additional insured endorsement is not CG 20 26. Some contracts accept blanket wording in place of a scheduled name. Some do not. The reviewer compares the contract sentence to the form in the packet. This page does not claim that a blanket form always fails, and it does not claim that it always works.
What the reviewer still confirms
The reviewer confirms that the form is CG 20 26, that the designated organization matches the contract, and that the dates cover the event or the lease obligation the requirement describes. Uncertain characters in the legal name stay visible. An unreadable page is an error, not a guessed schedule. The reviewer approves, rejects the extraction, or records an exception.
The request to the broker should name the venue or landlord, the event or the premises, and CG 20 26. If CG 20 10 or CG 20 37 is also missing, name those forms in the same request. DueFiles lists the missing form on the vendor upload page so the broker sees the request that matches the requirement. DueFiles does not sell insurance and does not replace the reviewer.
A landlord file and a venue file can both ask for CG 20 26 and still mean different dates. The landlord is usually concerned with the lease term and the premises. The venue is concerned with setup, the event, and teardown, often a few days. The designated organization on the endorsement has to be the legal entity in that contract, not the building's nickname. If the schedule names the venue and the contract also names a building owner, you have two entities to match, not one. Record each result.
CG 20 26 can sit in a packet next to CG 20 10 when a tenant is doing work in the building. The landlord may be scheduled on CG 20 26 while the construction contract also requires ongoing and completed operations for the owner. Those are not duplicates. Dropping CG 20 37 because CG 20 26 is present leaves the completed-operations requirement open. The reviewer confirms the form the requirement named, on the file for that party.
Event staff should be able to see the gap without reading the endorsement. The file can say: venue legal name, CG 20 26 missing, load-in date, liquor required or not. That is enough to hold the truck. It is not enough to skip the form once it arrives. Someone still compares the schedule to the contract. If the producer sends CG 20 10 instead, thank them for the page and keep CG 20 26 open if the contract asked for the designated-person form. Do not relabel CG 20 10 as CG 20 26 because both say additional insured. The numbers are the request the broker can satisfy.
Landlords and venues can both be right to ask for CG 20 26 and still be different files. Do not merge a lease requirement and an event requirement because the form number matches. The designated organization, the dates, and the contract sentence are what the reviewer compares. CG 20 10 and CG 20 37 remain available when those contracts also name ongoing or completed operations. They are additional requirements, not synonyms.
