You cannot take out a life insurance policy on just anyone — the person must have an insurable interest in you, and you must have their permission

Life insurance requires two things: insurable interest and consent. Insurable interest means you would suffer a real financial loss if the person died. Consent means they know you are buying the policy and agree to it. Without both, the insurance company will deny the claim, and in some cases you could face fraud charges.

The reason for these rules is straightforward: insurance exists to protect against loss, not to create a financial incentive for someone to die. If you could buy a policy on a stranger and collect when they died, the system would invite murder.

Key Takeaways

  • You can buy life insurance on a spouse, child, business partner, or anyone whose death would cause you direct financial harm, but only with their knowledge and written consent.
  • Insurable interest means you have a legitimate reason — shared debt, financial dependence, business obligation — not just a wish to collect money.
  • The insurance company will investigate the relationship and may require proof of consent before paying a claim.
  • Buying a policy on someone without their knowledge is fraud and can result in criminal charges, not just a denied claim.

Who has insurable interest in your life

Your spouse has insurable interest because they depend on your income and would face financial hardship if you died. Your children have insurable interest in you for the same reason — you support them. Your parents may have insurable interest if you help pay their bills or mortgage.

In business, a partner or co-owner has insurable interest in you because your death would disrupt the business or leave them liable for debts. A lender has insurable interest in a borrower — a bank can require you to carry life insurance as part of a large loan. An employer may have insurable interest in a key employee whose death would cost the company money to replace.

A friend, neighbour, or distant relative typically does not have insurable interest unless you have a specific financial obligation to them — for example, you co-signed a loan or you are the sole caregiver for their child and they depend on your income to support that arrangement.

Why the insurance company asks about your relationship

When you apply for life insurance, the company asks who the beneficiary is and what your relationship to them is. They are checking whether insurable interest exists. If you say the beneficiary is a stranger, they will ask follow-up questions: Do they depend on you financially? Do you have shared debt? Are you business partners?

If the answers do not add up, the company may deny the policy outright. If they issue it and you later file a claim, they may investigate the relationship and deny payment if they find no legitimate insurable interest. This is not a technicality — it is a core part of how life insurance works.

Consent and disclosure requirements

Even if insurable interest exists, you must have the person's permission. The insurance company will require the person being insured to sign the application or a separate consent form. This is not optional, and forging a signature is fraud.

Some policies require the insured person to undergo a medical exam or answer health questions themselves. This serves two purposes: it confirms they know about the policy, and it ensures the company has accurate health information. If someone applies for a policy on you without your knowledge, you will likely discover it when the insurance company contacts you for the exam or to verify information.

If you buy a policy on someone without their consent, the policy is voidable — the insurance company can cancel it, and if you file a claim, they can deny it and investigate you for fraud.

Policies on children and dependents

Parents can buy life insurance on their children because they have insurable interest — they would face financial loss if the child died (funeral costs, loss of future income if the child was expected to contribute, emotional and practical hardship). The parent must still disclose the policy to the child's other parent if they are married or in a custody arrangement, and some states require both parents to consent.

The amount of insurance on a child is usually limited. Most companies will not write a large policy on a minor because the insurable interest is smaller — the child is not yet earning income. A typical child policy might be $10,000 to $25,000, enough to cover funeral expenses and immediate costs, not $500,000.

Once the child reaches adulthood, they may be able to convert the policy to a larger amount or take it over, depending on the policy terms.

What happens if you try to buy a policy without consent

If you apply for a policy on someone without their knowledge, the insurance company will contact them during underwriting — usually to verify information or request a medical exam. At that point, the person will learn about the policy. They can refuse to participate, which will cause the application to be denied.

If you forge their signature or provide false information about their health or habits, you have committed fraud. The insurance company can report this to law enforcement. If you later file a claim on a policy obtained through fraud, the company will investigate and deny the claim. You could face criminal charges for insurance fraud, which carries fines and possible jail time depending on the state and the amount involved.

Business and creditor situations

In business, a buy-sell agreement often includes life insurance on each partner. Each partner buys a policy on the others so that if one dies, the proceeds can be used to buy out their share from their estate. This is legitimate because the surviving partners have clear insurable interest — they need the money to keep the business running and to avoid being forced into partnership with the deceased's heirs.

A creditor — such as a bank or mortgage lender — may require you to carry life insurance as a condition of the loan. This is called creditor-owned life insurance or key person insurance. The creditor has insurable interest because you owe them money. You must consent to this arrangement, and it should be spelled out in the loan documents.

Frequently Asked Questions

Can I buy life insurance on my ex-spouse?

Not without their consent, and most insurance companies will not approve it. You no longer have insurable interest — you do not depend on their income and would not suffer financial loss if they died. If you have children together and you are paying child support, you might have a limited insurable interest, but you would still need their permission and the company would likely limit the amount.

What if someone wants me to buy life insurance on them?

This is allowed if you have insurable interest. For example, if you are a business partner or you co-signed a loan together, they can ask you to buy a policy on them to protect the business or the loan. You both must consent, and the policy should be in writing. Make sure you understand why they are asking and what happens to the policy if your relationship changes.

Can I change the beneficiary on a policy without telling the insured person?

Yes, if you own the policy, you can change the beneficiary without the insured person's permission. However, if the insured person is also the owner (which is common), they must consent to any change. Check your policy documents to see who the owner is — it is usually the person being insured, but not always.

What if the insurance company suspects fraud?

The company will investigate before paying a claim. They may interview the beneficiary, review the application for inconsistencies, and check medical records. If they find evidence of fraud — forged signatures, false health information, or a policy taken out without consent — they will deny the claim and may report you to law enforcement. This can result in criminal charges and civil liability.
