1.2 Insurable Interest, Indemnity, and Adverse Selection
Key Takeaways
- Insurable interest prevents wagering; for life and health it must exist only at the time of application, not at the time of loss.
- Everyone has unlimited insurable interest in their own life; others must show a financial or close-family stake.
- The principle of indemnity restores the insured to pre-loss condition with no profit; life insurance is a valued exception.
- Adverse selection is the tendency of higher-risk applicants to seek coverage more aggressively than average risks.
- Underwriting, exclusions, waiting periods, and probationary periods are the main defenses against adverse selection.
Insurable Interest: Stopping the Wager
Insurable interest is the requirement that the policyowner stand to suffer a genuine financial or emotional loss if the insured event occurs. Without it, a policy becomes a bet on a stranger's death, which the law refuses to enforce. Insurable interest is what separates insurance from gambling at the contract level.
Timing Rule (heavily tested)
| Line of Coverage | When Insurable Interest Must Exist |
|---|---|
| Life insurance | At the time of application only |
| Health insurance | At the time of application only |
| Property insurance | At application and at the time of loss |
For life and health, once the policy is issued it stays valid even if the interest later disappears. Classic trap: a couple buys life coverage on each other, then divorces. The policy remains in force because insurable interest only had to exist when the application was signed.
Who Has Insurable Interest in a Life?
- Yourself - every person has unlimited insurable interest in his or her own life.
- Spouses and close family - presumed by the law of love and affection.
- Business partners - in each other, supporting buy-sell agreements.
- Employers - in key employees whose loss would harm the firm.
- Creditors - in a debtor, but limited to the amount of the debt plus reasonable interest and costs.
The creditor rule is a frequent exam point. A lender who is owed $40,000 may insure the borrower's life, but only for an amount reasonably related to that $40,000 - not $1,000,000. Insuring far beyond the debt would convert a legitimate creditor interest into a wagering contract.
Stranger-Originated Life Insurance (STOLI)
The insurable-interest requirement is also the law's defense against STOLI (stranger-originated life insurance), schemes in which investors with no genuine interest persuade an insured to take out a policy and then assign it to them for profit. Because the investor lacked insurable interest at inception, courts and statutes treat such arrangements as void wagering contracts. Note the contrast with legitimate viatical and life settlements, where a valid policy that already met the insurable-interest test at issue is later sold - that secondary sale is permitted because interest existed when the contract began.
Maria takes out a life insurance policy on her husband, naming herself owner and beneficiary. Three years later they divorce, and the policy is never changed. Her ex-husband dies the next year. What happens to the death benefit?
The Principle of Indemnity
The principle of indemnity holds that insurance should restore the insured to the same financial position held just before the loss - no better, no worse. Indemnity prevents a policyholder from profiting from a loss, which would invite moral hazard.
| Coverage | How Indemnity Applies |
|---|---|
| Health / medical expense | Reimburses actual covered expenses incurred |
| Disability income | Replaces a stated portion of lost income, never 100 percent |
| Life insurance | Exception - a valued contract paying the agreed face amount |
Why Life Insurance Is a Valued Contract
A human life cannot be objectively appraised after death, so life insurance is a valued policy: the death benefit (face amount) is fixed at issue and paid in full regardless of any attempt to measure the "true value" of the life lost.
Why Disability Pays Less Than 100 Percent
Disability income benefits are deliberately capped, commonly at roughly 60 to 66 and two-thirds percent of gross earnings. If a $5,000-per-month earner could collect a tax-favored $5,000 in benefits while not working, the morale hazard would discourage return to work. A $5,000 earner therefore typically receives about $3,000 to $3,333 per month, preserving the incentive to recover.
Adverse Selection
Adverse selection is the tendency of people with a higher-than-average chance of loss to seek insurance more eagerly, and in larger amounts, than average or below-average risks. A terminally ill applicant wants the maximum policy; a marathon runner in perfect health may skip coverage. Left unchecked, the pool fills with bad risks, claims exceed premiums, and rates spiral until healthy buyers leave entirely.
Insurers fight adverse selection with several tools:
- Underwriting - reviewing applications, medical records, and risk classes to accept, rate, or decline.
- Exclusions and riders - carving out high-risk causes such as aviation or hazardous sports.
- Probationary and waiting periods - delaying benefit eligibility for certain conditions (for example, a sickness waiting period or a disability elimination period).
- Pre-existing condition limits - restricting payment for conditions present before coverage began.
- Guaranteed-issue trade-offs - when health questions are waived, insurers offset the higher selection risk with graded death benefits or higher premiums.
Recognize the pattern: any policy provision designed to keep disproportionately bad risks from loading the pool is an answer to adverse selection.
Worked Illustration
Suppose an insurer expects average claims of $400 per insured and prices the premium accordingly. If healthy buyers stay away and only above-average risks enroll, true average claims might run $700. Premiums of $400 cannot cover $700 of claims, so the insurer must raise rates - which drives out the next-healthiest tier, raising the average again. This self-reinforcing spiral is the adverse selection death spiral, and it is exactly why underwriting and waiting periods are essential rather than optional.
An insurer adds a two-year graded death benefit and higher premiums to a guaranteed-issue final expense policy that asks no health questions. The primary purpose of these features is to control:
Insurable interest in third-party and business situations
Beyond family relationships, insurable interest supports several business arrangements the exam tests:
- A creditor has insurable interest in a debtor up to the amount of the debt (the basis for credit life).
- A business has insurable interest in a key employee whose loss would harm earnings, and partners/co-owners have insurable interest in one another to fund buy-sell agreements.
- An employer can insure employees' lives where a legitimate economic relationship exists.
In each case the amount of coverage should bear a reasonable relationship to the economic exposure.
Reinsurance and spreading risk
Insurers themselves manage adverse selection and large exposures through reinsurance, transferring part of a risk to a reinsurer. Facultative reinsurance covers a single specified risk negotiated case-by-case, while treaty reinsurance automatically covers a whole class of risks under a standing agreement. Reinsurance lets a primary (ceding) insurer write larger policies than its surplus alone would prudently allow.
A lender wants to insure a borrower's life so the loan is repaid if the borrower dies. What is the limit of the lender's insurable interest?
