Ice, Comparative Fault, and a Certificate of Insurance
A customer slips on ice in the parking lot of a Minnesota hardware store and fractures a wrist. Medical bills are $38,000 and lost wages are $6,000. Investigation shows the store's snow-removal contractor was contractually required to clear and sand the lot and to name the store as an additional insured. The contractor finished at 4:00 p.m.; the fall occurred at 6:00 p.m. The customer was looking at her phone and stepped over a curb that was plainly visible. The store carries a CGL with $1 million per occurrence, $2 million aggregate, $5,000 medical payments, and a $2,500 deductible. The contractor's policy has $1 million limits and an additional-insured endorsement; the store's file contains only a certificate of insurance.
1. If a Minnesota jury finds the customer 60% at fault, what does she recover, and what does the store's CGL owe on the liability claim?
Read the worked answer
Rule. Minnesota is a modified comparative-fault state. A claimant whose fault is greater than the defendant's is barred from recovery entirely; if fault is equal, or the claimant's is less, recovery is reduced proportionally.
Application. At 60% claimant fault, the customer's fault exceeds the store's 40%, so she recovers nothing on the negligence claim. The comparative-fault statute is a complete bar above the 50% line, not a proportional reduction.
CGL consequence. With no legal liability, the liability coverage part owes nothing for damages (though the insurer still owes a defense until the claim is resolved). Note that the store's liability here is thin on the merits anyway - a plainly visible curb, a phone distraction, and a contractor who cleared the lot two hours earlier.
The exception. CGL medical payments coverage responds to bodily injury caused by an accident on the premises regardless of fault, is not an admission of liability, and is not reduced by the comparative-fault finding. It pays up to the $5,000 limit. So the customer may still receive $5,000 even though she is barred from the liability claim.
2. If instead the customer is found 35% at fault, walk through the money and identify which policy pays first.

Step 1 - Gross damages. $38,000 medical + $6,000 lost wages = $44,000 in economic damages (assume no separate non-economic award).
Step 2 - Reduce for comparative fault. The store's share is 65%: 0.65 × $44,000 = $28,600.
Step 3 - Who pays first. The snow contractor assumed the snow-and-ice duty and named the store as an additional insured. If the AI endorsement is written as primary and non-contributory, the contractor's $1 million policy is the first dollar of defense and indemnity for the store. The store's own CGL then applies only as excess/other insurance, and its $2,500 deductible likely never comes into play.
Step 4 - If the endorsement is missing. The file holds only a certificate of insurance, which is evidence of coverage, not the endorsement itself. If the vendor's policy does not actually extend AI status to the store, or is written on a contributing basis, the store's CGL pays the $28,600 subject to the $2,500 deductible, and the store pursues the contractor by contract.
Defense. Defense costs are outside the limits and are owed in addition to any indemnity payment, regardless of the comparative-fault outcome.
3. What is wrong with the store's vendor-management file, and what would you fix?
Read the worked answer
The defect. A certificate of insurance proves only that a policy existed on the date printed. It does not prove the AI endorsement was issued, does not establish primary/non-contributory wording, does not show a waiver of subrogation, and does not bind the contractor's insurer to notify the store of cancellation. Certificates are routinely issued by brokers without authority to alter coverage, and many carriers disclaim that a certificate creates any rights.
Fixes.
- Obtain and read the actual additional-insured endorsement form (and the primary/non-contributory and waiver-of-subrogation endorsements) for every vendor with a snow/ice, liquor, or construction exposure.
- Set certificate expiry tracking and require renewed certificates naming the store before work each season.
- Confirm the contract's indemnity language is covered by the contractor's CGL contractual-liability coverage, and confirm the limits are adequate for a parking-lot exposure.
- Keep the risk-transfer file with the policy, and review the store's own CGL to see whether any gap must be filled by an umbrella.
