You cannot buy life insurance on just anybody — the person has to have what's called insurable interest
Insurable interest means you would suffer a real financial loss if that person died. You can buy life insurance on yourself, your spouse, your children, your business partner, or anyone else whose death would directly hurt your finances. You cannot buy a policy on a stranger or someone you have no financial connection to, even if you offer to pay all the premiums.
This rule exists to prevent life insurance from becoming a bet on someone's death — a situation where you might have a reason to want them dead. Insurance companies and state laws treat this seriously. If you try to buy a policy on someone without insurable interest, the company will deny it. If you somehow get one issued and then claim the death benefit, the insurer can refuse to pay and investigate you for fraud.
The person you're insuring also has to know about the policy and usually has to consent to it in writing. You cannot secretly take out a policy on someone without their knowledge.
Key Takeaways
- You can only buy life insurance on people whose death would cause you direct financial harm — yourself, a spouse, children, business partners, or key employees.
- The person being insured must know about the policy and usually must sign consent forms before the policy is issued.
- Insurance companies verify insurable interest during underwriting, and policies issued without it can be denied at claim time.
- Insurable interest must exist at the time you buy the policy, though it can change later without affecting the policy's validity.
Who counts as having insurable interest
You have insurable interest in your own life — that's the most straightforward case. You can buy as much life insurance as you want on yourself, as long as the underwriting process confirms you can afford the premiums and you're not over-insuring (buying more than your income or assets would reasonably replace).
You have insurable interest in your spouse's life because their death would affect your household finances, your ability to pay the mortgage, and your children's support. Most spouses can buy life insurance on each other without much friction during underwriting.
You have insurable interest in your children's lives because you support them financially and would face costs if they died — funeral expenses, lost income if you had to take time off work, and emotional hardship. Parents can buy life insurance on minor children, though the death benefit is usually capped lower than for adults.
You have insurable interest in a business partner's life if their death would harm the business or leave you liable for debts. You have insurable interest in a key employee if their death would damage your company's revenue or operations. In both cases, the amount of insurance should roughly match the financial loss you'd actually face.
Why the person being insured has to consent
Before a policy is issued, the insurance company will ask the person being insured to sign a consent form. This protects them from being secretly insured and protects the company from fraud. The consent form is part of the underwriting process — the company needs to know the person agrees to the medical exam (if required) and understands a policy exists in their name.
In some cases, like a parent insuring a minor child, the parent's consent as the legal guardian is enough. But for an adult, the adult themselves must consent. If you're buying a policy on a spouse or business partner, they will be contacted by the insurance company to verify they know about it.
After the policy is issued, the person being insured can request to see it, ask questions about it, and in some cases request changes. They cannot cancel it without your permission, but they can dispute it if they claim they never consented.
What happens if you try to insure someone without insurable interest
If you explore for a policy on someone you have no financial connection to, the insurance company will likely deny the process during underwriting. They will ask you to explain why you need insurance on this person and what financial loss you would face if they died. If your answer doesn't hold up, they reject it.
If somehow a policy is issued without proper insurable interest — which is rare — and you later try to claim the death benefit, the insurance company can deny the claim and investigate you. They may report you to state insurance regulators or law enforcement if they suspect fraud. This is a serious legal risk.
Some states have specific laws about insurable interest. For example, some states say you cannot buy life insurance on someone unless you are related to them by blood or marriage, or unless you have a clear business relationship. Other states are more flexible but still require the financial connection to be real and documented.
Insurable interest at the time of purchase versus later
Insurable interest must exist when you buy the policy. If you buy life insurance on your business partner because the partnership would suffer if they died, that's valid insurable interest. If you later sell the business or the partnership ends, the insurable interest disappears — but your policy stays valid. You can keep paying premiums and collect the death benefit if they die, even though you no longer have a financial stake in their survival.
This matters because it means you cannot use a change in circumstances to challenge a policy that was valid when issued. If you divorce your spouse, for example, the life insurance policy you bought on them during the marriage remains in force. You would need to contact the insurance company to remove yourself as beneficiary or cancel the policy if you no longer want it.
Special cases: Employer-owned life insurance and trusts
Employers can buy life insurance on their employees without the employee's knowledge in some cases, but this is heavily regulated. The employee must eventually be told, and the employer must have a legitimate business reason — usually that the employee's death would harm the company. These policies are called COLI (corporate-owned life insurance) or BOLI (bank-owned life insurance), and they come with strict tax and disclosure rules.
If you set up a trust and want the trust to own a life insurance policy, the trust itself becomes the policyholder. The trust can insure anyone the trust has insurable interest in — typically the person who created the trust, their spouse, or their children. The trust structure doesn't change the insurable interest requirement; it just changes who owns the policy and receives the death benefit.
How to verify insurable interest before buying
Before you explore for a life insurance policy on someone else, think through whether you would actually suffer a financial loss if they died. Write down the specific reason: "My spouse's income supports half our household expenses," or "This employee generates $500,000 in annual revenue for my business." Be honest about the amount. If you cannot articulate a real financial connection, you probably don't have insurable interest.
When you explore, the insurance company will ask you directly why you need insurance on this person and what your relationship is to them. Answer clearly and truthfully. During underwriting, the company may contact the person being insured to confirm they know about the policy and consent to it. If there are any red flags — if the person says they don't know you, or if the amount of insurance seems wildly out of proportion to any real loss — the company will deny the process.
If you're insuring a business partner or key employee, have documentation ready: a partnership agreement, an employment contract, or a business valuation that shows why their death would harm the company. This makes the underwriting process faster and shows the insurance company you have a legitimate reason for the policy.
Frequently Asked Questions
Can I buy life insurance on my adult child?
Yes, if you can show you would face a financial loss if they died — for example, if they live with you and you support them, or if they work in your family business. You will need their written consent. If they are financially independent and you have no financial connection to them, you likely cannot get a policy approved.
What if the person I want to insure refuses to consent?
You cannot buy the policy without their consent. If they will not sign the consent form, the insurance company will not issue the policy. You cannot force someone to be insured or work around their refusal.
Can I change the beneficiary on a life insurance policy I own on someone else?
Yes, as the policy owner you can change the beneficiary at any time, even if the person being insured objects. However, if you remove them as beneficiary and name someone else, they may find out and dispute it. The policy itself remains valid as long as you pay the premiums.
Does insurable interest have to be the same amount as the death benefit?
No, but the death benefit should be reasonable relative to the actual financial loss. If you insure a business partner for $5 million but the partnership is worth $200,000, the insurance company may cap the benefit or deny the process. Underwriters look for a logical connection between the insurable interest and the amount of coverage.
What if someone dies and the insurance company questions whether insurable interest existed?
The company will investigate before paying the claim. They will review the process, the consent forms, and any documentation you provided about your relationship to the person. If they find evidence of fraud — that you had no real financial connection and took out the policy as a bet on their death — they can deny the claim entirely.
