You cannot buy a life insurance policy on just anyone — the person must have what insurers call insurable interest, and you typically need their knowledge and consent
Insurable interest means you would suffer a real financial loss if that person died. A spouse, child, business partner, or someone who owes you money can have insurable interest. A stranger cannot. This rule exists to prevent insurance from becoming a bet on someone's death — which would create an incentive to harm them.
In practice, this means you cannot walk into an insurance office and buy a policy on your neighbour, a celebrity, or anyone else you have no financial relationship with. The insurer will ask who the insured person is, why you want coverage, and will usually require that person to sign consent forms and answer health questions themselves.
Key Takeaways
- You can buy life insurance on a spouse, child, business partner, or anyone whose death would cause you direct financial harm, but the insured person must consent and usually answer health questions.
- Insurable interest prevents life insurance from becoming a financial incentive to harm someone, which is why insurers verify your relationship to the person being insured.
- The person whose life is insured does not have to be the one who pays the premiums, but they must know about the policy and agree to it.
- Some policies on adult children or elderly parents require the insured person to sign consent forms, while others may not depending on the insurer and policy type.
Who counts as having insurable interest
Your spouse has insurable interest because you share finances, debts, and household expenses. If your spouse dies, you lose their income and may face mortgage payments, childcare costs, or medical bills alone. Most insurers will let you buy a policy on a spouse without much friction.
Your children have insurable interest because you support them financially. You can buy a policy on a minor child, though the death benefit is usually capped lower than for an adult. Some insurers will not sell policies on very young children at all.
A business partner has insurable interest because their death affects the business's value and your income. Many business partnerships use life insurance to fund a buy-sell agreement — a contract that says the surviving partner buys the dead partner's share from their estate using the insurance payout.
An elderly parent has insurable interest if you are their primary caregiver or stand to inherit from them. Some adult children buy policies on parents to cover funeral costs or to replace the parent's income if the child relied on financial support from them.
A lender can have insurable interest in a borrower. Banks sometimes require life insurance on a large loan — for example, a mortgage lender might require you to carry a policy that pays off the remaining balance if you die.
Why the insured person must consent
The insured person must know about the policy and agree to it. This is not just a rule — it is a legal requirement in most states. The insurer will ask the person being insured to sign a consent form, and they will usually have to answer health questions or take a medical exam.
Consent protects the insured person from being used. Without this requirement, someone could buy a large policy on a stranger and then have a financial reason to harm them. Requiring the insured person's signature and medical information makes that scheme impossible.
The person who pays the premiums does not have to be the insured person. A parent can pay premiums on a child's policy. A business can pay premiums on a key employee's policy. But the insured person must still consent and provide their health history.
What happens if you try to buy a policy without consent
If you explore for a policy on someone without their knowledge or consent, the insurer will discover this during underwriting. They will contact the insured person directly to verify they know about the policy and agree to it. If the insured person says no, the process will be denied.
If somehow a policy was issued without proper consent and the insured person later found out, they could challenge the policy in court. In some cases, a court might void the policy entirely, meaning the insurer would not pay the death benefit even if the person died.
Attempting to buy insurance on someone without their consent can also raise fraud flags. If an insurer suspects you are trying to create a financial incentive to harm someone, they may report the attempt to law enforcement.
Policies on adult children and aging parents
Adult children can buy policies on aging parents, but the rules vary by insurer. Some require the parent to sign consent forms and answer health questions, just as they would for any other policy. Others have streamlined processes for adult children buying coverage on parents, especially if the parent is in poor health.
The death benefit on a parent's policy is usually smaller than on a spouse's policy, because the insurer assumes the financial loss is smaller. You are not losing a co-earner or co-borrower; you are covering funeral costs and possibly lost financial support.
Parents can also buy policies on adult children, though this is less common. The same insurable interest rule applies: the parent must have a financial reason for the coverage, and the adult child must consent.
Policies on key employees and business owners
A business can buy life insurance on a key employee — someone whose death would harm the company's revenue or operations. This is called key person insurance or key man insurance. The employee must consent and provide health information, just as they would for any other policy.
The business pays the premiums and receives the death benefit. The money can be used to cover the cost of finding and training a replacement, to pay off debts the key person was responsible for, or to keep the business running during the transition.
In a partnership or small business, partners often buy policies on each other to fund a buy-sell agreement. If one partner dies, the policy pays out to the surviving partner, who uses the money to buy the dead partner's share from their estate. This keeps the business intact and prevents the dead partner's heirs from becoming unwilling co-owners.
The role of health information and medical exams
Because the insured person must consent, they will have to provide detailed health information. This includes medical history, current medications, lifestyle habits like smoking, and sometimes results from a medical exam. The insurer uses this information to assess risk and set the premium.
If the insured person lies on the health questionnaire, the insurer can deny a claim later if they discover the lie. This is true even if you are the one who paid the premiums. The policy is based on the insured person's honest health disclosure, and fraud voids that agreement.
For policies on young, healthy people, the insurer may not require a medical exam — just a questionnaire. For larger policies or older applicants, a medical exam is standard. The exam might include blood work, an EKG, or other tests depending on the policy amount and the person's age.
Frequently Asked Questions
Can I buy life insurance on someone without telling them?
No. The insured person must consent and sign forms. The insurer will contact them directly to verify they know about the policy. If they say no, the process will be denied. If a policy was somehow issued without proper consent, it could be voided later.
Can I buy life insurance on a stranger?
No, because you have no insurable interest. You would not suffer a financial loss if a stranger died, so insurers will not sell you a policy on them. Insurable interest must exist between you and the insured person.
Can I buy life insurance on my adult child?
Yes, if you have insurable interest — for example, if they live with you and you support them financially, or if you are their caregiver. Your adult child must consent and provide health information. The process is the same as for any other policy.
What if my spouse does not want to take a medical exam?
The insurer may deny the process or offer a policy with a higher premium and lower death benefit. Some insurers have no-exam policies for smaller amounts, but they usually cost more. Your spouse can choose not to proceed, which means the policy cannot be issued.
Can a business buy life insurance on an employee without their consent?
No. Even though the business has insurable interest in a key employee, the employee must still consent and provide health information. The insurer will verify this directly with the employee before issuing the policy.
