Additional insured vs certificate holder: the two-paragraph version

The honest answer is that a certificate holder gets a piece of paper and an additional insured gets a piece of your policy. That’s the whole difference. It’s also the difference between a GC who can read your certificate and a GC who can file a claim on it. Most of the certificate requests that come through our certificates desk mix the two up, usually because the person asking has a checklist and the person answering has a deadline. Here’s the two-paragraph version, then the long one for the day a coordinator in Castle Rock bounces your certificate an hour before the excavator is supposed to unload.

The two paragraphs

Certificate holder. The holder is the name and address in the bottom-left box of the certificate. They get a one-page snapshot that says you carry the policies listed, with the limits listed, on the date listed. It proves you have insurance. It gives them nothing under your policy, and the standard form says so in plain print. Most HOAs, property managers, and permit desks stop here.

Additional insured. An additional insured is added to your policy by endorsement, so that if a claim comes in tied to your work for them, your general liability responds for them too. That’s what a GC’s insurance exhibit is asking for when it lists form numbers, says “primary and non-contributory,” or wants “ongoing and completed operations.” The certificate can only truthfully say those things if the endorsement exists. The endorsement is the coverage. The certificate is the receipt.

The long version

What the certificate is for

A certificate is evidence, not a contract. It shows the policies, the carrier’s name, the policy numbers, the effective dates, and the limits. The holder keeps it in a file so that when something goes wrong, they know who to call and what to expect. Nothing on the page changes what your policy does.

The one thing on a certificate that trips people up is the description box. Contractors and agents write all kinds of things in it: the project address, “additional insured per written contract,” “waiver of subrogation applies.” Those lines are true only if the policy actually carries those endorsements. A certificate with the right words and a policy without the right forms is the worst of both worlds, because the GC thinks they’re covered and you think you’re done.

What the endorsement is for

The additional insured endorsement rewrites who counts as an insured under your general liability policy for one specific purpose: claims arising out of your work for that party. Two forms come up on almost every construction exhibit.

• CG 20 10 typically covers the additional insured for your ongoing operations. The trench is open, the Yanmar mini skid steer is running, a delivery driver steps in the hole. The GC gets sued along with you and tenders it to your policy.
• CG 20 37 typically covers completed operations. The job is closed out, the pavers are down, and the wall shifts on expansive clay a couple of winters later. The owner sues the GC, the GC tenders to your policy under the completed-ops form.

A GC asking for one and not the other is a GC who hasn’t been sued after close-out yet. Most exhibits ask for both, and most policies written for contractors carry a blanket version of each: the endorsement covers whoever your written contract requires, without naming each one. Scheduled endorsements name a specific party and nobody else.

There is a third piece that rides along: primary and non-contributory wording, which says your policy pays first and the GC’s policy doesn’t chip in. That’s its own clause on the exhibit, and the article on reading a GC’s requirements takes it apart along with the rest of the page.

Who asks for which

The two public examples are worth reading side by side, because they show the difference in one sentence each.

Colorado Springs wants to be the holder. CDOT wants to be an insured. Same trade, same machine, different piece of paper. If you do utility trenching on both a city street and a state highway, you’ll produce both in the same month, and the second one is the one that has to exist on the policy before the certificate can say so. Most excavation contractors who take on public work hit that sequence in their first year of it.

Where it goes wrong

We see three versions of the same problem.

The box says it, the policy doesn’t. An agent types “additional insured” into the description box on a policy that was never endorsed. The GC’s coordinator asks for a copy of the endorsement, there isn’t one, and now the fix is a policy change with the carrier, not a reprint. What we don’t control is how long the carrier takes to issue a new endorsement. What we do control is checking before we send.

Ongoing only. The policy carries CG 20 10 and nothing else. The job closes out clean. The claim comes after, on the wall that moved or the septic line that settled. The GC tenders under completed operations, the policy doesn’t have the form, and the GC’s carrier comes looking for you directly instead. Septic installers and hardscape crews carry this tail longer than anyone.

GL only, when the contract wanted more. The exhibit asked for additional insured status on the GL, the auto, and the umbrella. The GL got endorsed. The umbrella didn’t, and the auto never came up. On a serious injury the GC’s tender climbs past the GL limit and finds nothing waiting above it. The commercial auto article covers the truck side of that.

What it costs you

Not the endorsement charge, which is usually modest and sometimes nothing on a blanket form. The real cost is limits. When a GC tenders a claim to your policy as an additional insured, their defense and any payment come out of your occurrence limit and your aggregate, the same pool your own claims draw from. A GC with a big claim can use up a $1M occurrence limit on a job where your crew was one of eight subs. That’s why the additional insured question and the umbrella question are the same conversation, and why the exhibit that asks for both is not being greedy. It’s being accurate about what a serious claim looks like.

What to do before you sign

Read the exhibit and find two words: “holder” and “insured.” If the contract only asks for a certificate, you’re the first paragraph. If it asks for additional insured status, form numbers, “primary and non-contributory,” or “completed operations,” you’re the second paragraph, and the question is whether your policy already carries those forms.

Send the exhibit to us with the certificate request. We check the policy first. If the forms are there, the certificate usually goes out the same business day; it depends on the carrier and what the holder is asking for. If they aren’t, we call you before anything goes out, because the fix is on the policy and you should know that before the excavator is on the trailer.

Where to go from here

If you’re an existing client and a GC just sent the exhibit, the certificates page lists exactly what to send us. If you’re not a client yet and you’re about to sign your first GC contract, Get Insured starts with the contract, because that’s what the policy has to be built to satisfy. And if you already have a policy and aren’t sure which forms are on it, that’s the first thing we mark up in a policy review.
