CO Property & Casualty common mistakes

CO Property & Casualty · Understand the traps and how to avoid them.

Mistake 1

Marks a property policy as invalid because the insured acquired the property after the policy was written, or marks a life policy as void because the insured's insurable interest changed later.

Candidates memorize 'there must be insurable interest' as one rule and apply a single timing test to every line of business.

What to do instead

Attach the timing to the line: property/casualty requires insurable interest at the time of loss (ownership, custody, or financial exposure is enough), while life insurance requires it only at policy inception and the policy stays valid if it later disappears. When a question mentions 'when,' ask which line you are in before answering.

Mistake 2

Uses 'waiver' and 'estoppel' interchangeably, or says an insurer's agent can never give up a policy requirement.

Both appear in the same textbook paragraph and both involve an insurer giving up a right, so the definitions blur under time pressure.

What to do instead

Memorize them as a pair with a sequence: waiver is the voluntary relinquishment of a known right (the act), estoppel is the legal bar that prevents the insurer from later reclaiming that right once the insured has relied on it to their detriment (the consequence). If the question asks what the insurer did, it is waiver; if it asks why the insurer cannot change position, it is estoppel.

Mistake 3

Applies the coinsurance penalty formula to every property loss, including policies written at agreed value or where the limit already equals or exceeds the coinsurance requirement.

The penalty formula is the most drilled calculation in property insurance, so candidates reach for it whenever a limit and a value appear in the same question.

What to do instead

Run a two-question gate before any math: (1) Is this policy actually written on a coinsurance basis, or is it agreed value / no coinsurance? (2) Is the limit at least equal to (coinsurance percentage x value at time of loss)? If either answer removes the penalty, pay the loss up to the limit and stop. Only compute (limit / required amount) x loss when both answers keep the penalty in play, and cap the payment at the policy limit.

Mistake 4

Assumes the HO-3 gives open-peril ('all risk') coverage to personal property because the policy is described as a 'special form.'

The HO-3's special status applies only to Coverages A and B (the dwelling and other structures), but candidates carry the label across the whole policy.

What to do instead

Build a form-to-trigger table and recite it: HO-2 broad form (named perils on both dwelling and contents), HO-3 special form (open peril on A and B, named peril on C), HO-5 comprehensive form (open peril on A, B, and C). On any perils question, first identify the form, then identify which coverage letter is being asked about.

Mistake 5

Calculates a business income loss starting the day of the physical damage, or forgets to add extra expense and continuing expenses when totaling the loss.

The waiting period and the period of restoration feel like the same concept, and business income is mentally filed as 'lost profit' rather than 'lost net income plus continuing expenses.'

What to do instead

Work the timeline out loud: the period of restoration begins 72 hours after the direct physical loss (the waiting period) and ends when the property could reasonably be repaired with due diligence, not when the insured actually finishes. Then build the loss as net income lost plus continuing normal operating expenses, and treat extra expense as a separate coverage that pays even when it reduces the business income loss.

Mistake 6

Says a claim is covered under a claims-made policy because the injury and the report both happened during the policy period, ignoring the retroactive date, or says a claim is covered under an occurrence policy because it was reported during the term.

Both policies list dates in the declarations, and candidates default to 'the report date is what matters' because that is how most real-world claims are discussed.

What to do instead

Draw three markers on a timeline before choosing: date of injury, retroactive date, and date the claim is made or reported. Occurrence trigger: the injury date must fall inside the policy period; the report date is irrelevant. Claims-made trigger: the claim must be made during the policy period AND the injury must be on or after the retroactive date. If any marker falls outside, the answer is no coverage under that policy.

Mistake 7

Treats a certificate of insurance as if it grants coverage, or uses 'additional insured' and 'certificate holder' as synonyms.

In agency practice the certificate is the document that gets requested, forwarded, and filed, so it reads like the thing that provides protection.

What to do instead

State the rule in one line each time: a certificate is evidence of coverage only and cannot create, extend, or amend coverage; only a policy endorsement can add an additional insured. A certificate holder receives proof, not status under the policy. If the question asks who is protected, the answer must trace to an endorsement or the policy's定义 of insured, never to a certificate.

Mistake 8

Places libel, slander, false arrest, or invasion of privacy claims under Coverage A of the CGL instead of Coverage B.

All CGL coverages sit in one form and candidates classify by 'it's a liability claim, so it goes in the bodily injury coverage.'

What to do instead

Anchor each coverage to its injury type: Coverage A pays because of bodily injury or property damage; Coverage B pays because of personal and advertising injury (libel, slander, disparagement, false arrest, wrongful eviction, invasion of privacy, infringement of copyright or slogan in an advertisement); Coverage C pays medical expenses regardless of fault and without a liability determination. Sort the injury first, then select the coverage letter.

Mistake 9

Applies a strict 'any fault bars recovery' contributory negligence rule to a Colorado negligence question, or lets a plaintiff who is 50% at fault recover.

General study material often summarizes Colorado only as a 'comparative negligence' state without the cut-off, and candidates import the common-law rule they learned first.

What to do instead

Memorize the Colorado rule with its number: Colorado uses modified comparative negligence, and a plaintiff is barred from recovering when their own negligence is 50% or more. Below 50%, the plaintiff recovers damages reduced by their percentage of fault. On any Colorado negligence question, compute the plaintiff's percentage first, then apply the bar before splitting damages.

Mistake 10

Assumes Colorado is a no-fault state with mandatory PIP for private passenger autos, or picks liability limits other than 25/50/15 when asked for the state minimum.

Colorado sits among states with very different auto frameworks, and many national prep outlines describe no-fault states alongside it.

What to do instead

Fix the Colorado auto facts as a short list: minimum liability limits of $25,000 per person / $50,000 per accident for bodily injury and $15,000 for property damage; no no-fault system and no mandatory PIP for private passenger autos; uninsured motorist coverage must be offered. When a question mentions PIP in a Colorado private passenger context, treat it as coverage that may be offered, not one the law requires.
