Insurable Interest

Life insurance traditionally works as a form of self-insurance.  You purchase a policy over yourself, and you name someone as a beneficiary, typically a spouse.

When you pass away, whether from natural causes in decades or from an unexpected tragedy, your life insurance policy triggers and your benefits are paid out to that beneficiary.

That’s not the only way it can operate, however.  Another relatively common way life insurance can work is by taking out a life insurance policy on someone else.  

For example, a husband might take out an insurance policy on their wife; if their wife passes away, they receive the benefits.  Meanwhile, the wife can take out a policy on the husband for the same effect.

Life insurance is also not limited to spouses.  You can purchase life insurance for anyone (within limits) whose loss would be a financial, emotional, or other hardship to you.  

While this is typically spouses, it can also include business partners, children, and even key employees in a company.  You can also take out a policy on your parents (assuming they don’t have one of their own) and former spouses, siblings, and others.

Every life insurance policy involves three parties: the insured, the purchaser, and the beneficiary.  

This can be three different people (a husband purchases life insurance to cover the wife, which pays out to the child), or two roles can be filled by one person (a husband buys life insurance to cover himself and payout to the spouse or child.)

One thing you’ve probably read in fiction is the idea of taking out a life insurance policy on someone and then “bumping them off” to receive a payout.  

It’s an old concept from mystery and thriller stories. Still, it virtually never happens in real life for two significant reasons, one of which we’re discussing in detail today: Insurable Interest.

So, what is Insurable Interest, how does it limit your insurance policy decisions, and how do you navigate it when you want to buy a policy?  Read on to find out more.

Insurance Fraud

Limiting Insurance Fraud with Insurable Interest

Insurable Interest is a mechanism insurance firms use to limit who can purchase insurance for another.  It helps prevent things like buying insurance for someone you’ve never met.

So what is insurable interest?

“The interest that a person has in something such as a particular property or another individual, which means that the person would suffer a loss should that property or individual be harmed.

In insurance law, you can only buy insurance for something or someone in which you have an insurable interest.” – Association of British Insurers

You can only insure something or someone if you would suffer a loss if that something were stolen or destroyed or if someone dies.  You can only insure a car if you own that car; you can only insure a house if you own the house; and you can only insure a person if you have a vested interest in that person.

In essence, you need to receive some kind of benefit from the individual you’re insuring remaining alive, such that their loss is your loss.  This is most often financial, but can be other forms of loss as well, particularly emotional, which is a primary basis for insuring a spouse with no income.

Who Needs Insurable Interest?

Insurable Interest needs to be proven to an insurance company to buy a life insurance policy on someone, but there’s more to it than just proving your own interest.  

Insurable interest must exist for both the purchaser of the policy and the beneficiary of the policy.  In some cases, those are the same person; you buying a policy on your spouse for your own benefit.  

In other cases, the purchaser and the beneficiary may be different, in which case both parties must have insurable interest.

Who Needs Insurable Interest

Insurable interest must be presented and proven to the insurance company at least twice, once when the policy is purchased and once again when it’s paid out.  Insufficient proof of insurable interest is one of many reasons why a payout can be denied.

“Insurable interest is a nonnegotiable aspect of life insurance policies. Without an insurable interest, the policy can be void or denied.

It is the duty of the policy owner to prove that they have an insurable interest in the insured party. Proof must be presented at application as well as at the end of the policy when the insured has passed away.” – Value Penguin

There’s an exception to this.  You are always, by default, considered to have an insurable interest in yourself.  Therefore, if you purchase a policy for yourself, you don’t need to prove your insurable interest in yourself.  

Furthermore, whoever you name as beneficiary does not need to prove insurable interest in you because it’s assumed you would only pick someone as a beneficiary if such an interest exists.

This effect also extends to certain blood relationships and direct dependents.  Spouses, children (including adopted children), siblings, parents, grandparents, grandchildren, and similar relationships are assumed to have insurable interest by default.

This allows insurance companies to avoid having to investigate simple family dynamics, sort out family animosity, make judgment calls, or otherwise cause problems. At the same time, they can then focus on the more exotic cases where insurable interest may need to be proven.

Is Insurable Interest Different for Different Kinds of Life Insurance?

Term life insurance lasts for a fixed duration, usually 10, 20, or 30 years.  If you outlive the duration of the insurance term, you lose the benefits unless you either purchase a new term (for usually a significantly higher premium) or roll it over into permanent life insurance.

Meanwhile, permanent life insurance is much more like traditional insurance, which works as long as you continue paying premiums.


So, does insurable interest differ between these?  The simple answer is no.  Insurable interest is a singular concept and applies to both kinds of life insurance.

The only significant difference is that, for term life insurance, if you buy a new policy, you may need to prove insurable interest again as part of the process.  This depends on whether you’re rolling over your previous term into a new term, or you’re changing insurers or policies in some way that would necessitate a new evaluation.

How is Insurable Interest Proven?

Insurable interest doesn’t need to be proven in the case of blood and marriage relations, but in other cases, it does.

“To confirm that an insurable interest is present, a life insurance company will usually talk to the policy owner, beneficiary and insured.

They will investigate the relationship to the proposed insured and evaluate if there is an insurable interest. If an insurable interest is not found, the policy would be denied at the application or the death benefit would not be paid out.” – Value Penguin

Outside of cases where proof isn’t necessary, generally, there will be two elements to proving insurable interest.  The first is some financial statements that indicate the beneficiary of the policy is dependent on the insured.

So, for example, consider a case where a child has been abandoned by their parents and is being raised (but not legally adopted by) an aunt and uncle.  

The aunt and uncle can take out a life insurance policy on themselves for the child’s benefit.  However, since aunt/uncle relationships do not fall into the automatic insurable interest relations category like parental relationships, they must prove that insurable interest.  

Fortunately, given that they pay for rearing the child, those financial statements will be easy to come by.

How Is It Proven

The second element is a little less formal and typically involves a simple phone interview with a representative of the insurance company.  They’ll ask some questions about the relationship between the insured and the beneficiary, and if all seems satisfactory, insurable interest will be confirmed.

Most of the time, as long as there’s a legitimate relationship and reason for life insurance, there won’t be any reason to deny insurable interest.  It’s only in cases where fraud is likely or obvious, or in business relationships where things can be much more complicated, that investigations get more challenging.

What Happens if Insurable Interest Isn’t Proven?

“Sometimes, insurable interest cannot be proven. For instance, you would not be able to take out a life insurance policy on your elderly neighbor just because they are sick and may die soon if you cannot prove you would face financial hardship after they pass.” – Bankrate

In cases where insurable interest can’t be proven or the proof supplied is deemed inadequate or questionable by the insurance company, only one thing can happen: the insurance company denies the application.

What Happens if It Isnt Proven

When there’s no insurable interest, there can be no insurance.  Consider other forms of insurance; you can’t insure your neighbour’s car and get a payout if they wreck it.  It’s the same concept.  Insurance companies don’t want to offer contracts that can end in fraudulent payouts.

“Say, for example, you have an elderly neighbor who is 90 years old. You consider taking out a life insurance policy on your neighbor as she does not have many more years to live. This would not be a situation where an insurable interest would be present, as you would not suffer a financial loss from the death of your neighbor.” – Value Penguin

This is also why there’s another interview when life insurance comes to fruition and needs to be paid out.  If insurable interest has disappeared along the way, the insurance company is within their rights to deny the payout.  

Most of the time, this doesn’t happen, especially for standard life insurance (particularly the kind with insurable interest built in, like between spouses or blood relations). Still, it can be more common between business partners and other such cases.

The Second Component of Life Insurance

Above, we mentioned that insurable interest is one of two components designed to help prevent insurance fraud.  The second component is critical as well: consent.

Consent is simple.  The person who is being insured – and whose death will trigger the insurance payout – needs to consent to having the insurance policy taken out.  The insurance company will contact the insured and will need to obtain that consent before they can issue a policy.

Second Component

If you’re insuring yourself, of course, consent is easy.  It’s trickier when insuring someone else, like a spouse, child, or parent.  It’s also required in business partnerships where life insurance on a critical employee or executive is purchased; that critical employee must also give their consent.

Much like insurable interest, consent is obtained relatively easily, usually by signing paperwork.  And, much like insurable interest, if there’s no consent, there’s no policy.  The insurance company will not issue a policy on someone who does not consent to be insured.

Consent is a primary mechanism to keep individuals informed.  You can’t buy a policy on someone without their knowledge, because their consent is required.
