Insurable interest
The rule that stops insurance becoming a bet on other people.
Insurable interest means you must stand to suffer a genuine loss from the thing you're insuring. Without it, a policy generally isn't valid.
It's the rule that separates insurance from wagering, and it exists for reasons that become obvious once you consider the alternative.
Why it exists
Without the requirement, anyone could take out a policy on a stranger's life and profit from their death. That's not a theoretical concern — it's why the rule was established.
The same principle applies to property: you can't insure a building you have no stake in.
Where it's generally recognised in life insurance
- Yourself
- A spouse or domestic partner
- Close family members you depend on financially
- A business partner, under a buy-sell arrangement
- A key employee whose loss would harm the business
- Someone who owes you a substantial debt, in some circumstances
The timing rule differs by product
For life insurance, insurable interest generally must exist when the policy is taken out — not necessarily when a claim arises. A policy validly issued on a spouse typically doesn't become invalid on divorce.
For property insurance, the interest generally must exist at the time of loss. If you sold the car, you no longer have an interest in it.
Where it comes up in practice
Most people never think about it because it's satisfied automatically. It surfaces in business arrangements, in insuring a parent, and occasionally where someone wants a policy on a person they're not related to.
Consent matters too: an adult being insured generally has to consent and participate in the application.
Common questions
Generally yes where there's a financial interest, and the parent typically has to consent and participate in the application. Insurers will ask about the relationship and the reason.
For life insurance it generally must exist when the policy is issued rather than continuously. For property it generally must exist at the time of loss.
Commonly yes, under buy-sell or key person arrangements — those are standard uses of the principle.
