You cannot buy life insurance on just anyone — the person must have an insurable interest in you, and usually you need their knowledge and consent
Life insurance requires what the industry calls insurable interest. That means the person buying the policy would suffer a real financial loss if the person being insured died. You can buy a policy on yourself. You can buy one on a spouse, because their death would affect your finances. You can buy one on a business partner or key employee, because their death would harm the business. But you cannot buy a policy on a stranger or a distant relative you have no financial ties to — and you cannot buy one on someone without their knowledge.
The insurable interest rule exists to prevent murder-for-profit. Without it, someone could take out a large policy on a stranger, then kill them to collect. Insurance companies and state regulators treat this seriously. If you try to buy a policy on someone without their consent, the company will deny the claim if that person dies. If you already own a policy and the person dies under suspicious circumstances, the insurer may investigate whether you had a motive to harm them.
Key Takeaways
- You can buy life insurance on yourself, your spouse, your children, and business partners or employees — but only if their death would cause you financial harm.
- The person being insured must know about the policy and usually must sign consent forms, even if you are paying the premiums.
- Insurable interest must exist at the time you buy the policy, not just at the time of death.
- If you buy a policy on someone without their knowledge or consent, the insurance company will likely refuse to pay the claim.
Who has insurable interest in you
Your spouse has insurable interest because your death would disrupt their household finances, leave them with debt, or force them to raise children alone. Your children have insurable interest in you because you support them. Your parents may have insurable interest if you are still financially dependent on them or if you would inherit their debts.
A business partner has insurable interest in you because your death could collapse the business or force them to buy out your share from your estate. A lender has insurable interest in you — that is why mortgage companies require homeowners to carry homeowners insurance, and why some lenders require life insurance on loans above a certain amount. An employer may have insurable interest in a key employee whose death would cost the company money to replace or whose skills are irreplaceable.
A distant relative, a friend, or someone you know casually does not have insurable interest unless there is a specific financial tie. You cannot buy a policy on your neighbor, your coworker, or your ex-partner just because you want to.
Consent and disclosure requirements
Even if insurable interest exists, the person being insured must know about the policy. In most states, they must sign a consent form acknowledging that they understand a policy is being taken out on them. Some states require the insured person to sign the application itself. The insurance company will ask for this documentation before issuing the policy.
The reason is practical: if someone dies and the beneficiary tries to collect, the insurance company will contact the deceased's family to verify the policy was legitimate. If the family says the person never knew about it, the claim becomes suspicious. The company may deny payment or launch an investigation.
You do not need the insured person's permission to be the beneficiary — you can collect the money when they die. But you do need their knowledge and consent to buy the policy in the first place.
Insurable interest must exist when you buy the policy
The timing matters. Insurable interest has to exist at the moment you purchase the policy, not just when the person dies. If you buy a policy on your spouse and then divorce, the policy does not automatically become invalid — you own it and can keep paying for it. But if you tried to buy a policy on someone you had no connection to, and then later married them or went into business with them, that policy would still be invalid because insurable interest did not exist when you bought it.
This is another safeguard against fraud. It prevents someone from buying a policy on a stranger, waiting years for a relationship to develop, and then claiming insurable interest retroactively.
What happens if you buy a policy without insurable interest
If you try to buy a policy on someone you have no financial connection to, the insurance company will likely reject the application during underwriting. They will ask questions about your relationship to the insured person and why you need the policy. If your answers do not establish insurable interest, they will decline.
If somehow a policy was issued without proper insurable interest and the person dies, the insurance company can refuse to pay the claim. They may also investigate whether you had a motive to harm the insured person. In rare cases, if the death looks suspicious and the company believes you bought the policy to profit from murder, they can report the matter to law enforcement.
Life insurance on children
Parents have insurable interest in their children and can buy life insurance on them. The death benefit is usually modest — often $5,000 to $25,000 — because the child does not earn income and does not support the household. The policy covers funeral costs and any medical bills from a final illness. Some parents also buy small policies to lock in the child's insurability; if the child develops a health condition later, they will already have coverage in place.
Children cannot buy life insurance on themselves until they reach the age of majority, usually 18. At that point, they can buy a policy on themselves without parental consent.
Business life insurance and key person policies
A business can buy life insurance on an owner or key employee if that person's death would harm the company financially. This is called key person insurance or key man insurance. The business is the beneficiary and collects the death benefit to cover the cost of finding and training a replacement, paying off business debts, or keeping the company afloat during the transition.
For this type of policy, the business must have the employee's written consent. The employee should understand that the company owns the policy and will collect the benefit if they die. Some companies disclose this to employees; others do not, though the employee will be asked to sign consent forms during the underwriting process.
Frequently Asked Questions
Can I buy life insurance on my adult child?
Yes, if you have insurable interest — meaning their death would cause you financial harm. This might apply if they live with you and you support them, or if you would inherit their debts. They must consent to the policy, usually by signing a form. If they are financially independent and you have no financial ties, insurable interest may not exist.
What if I want to buy a policy on someone but they refuse to consent?
You cannot buy the policy without their consent. The insurance company will not issue it. If you already own a policy on someone and they ask you to cancel it, you can do so, but you cannot force them to keep it in place or prevent them from contacting the company to verify it exists.
Can a creditor buy life insurance on me?
A creditor has insurable interest in you if you owe them money, because your death could leave the debt unpaid. Some lenders require borrowers to carry life insurance as a condition of the loan. However, the creditor cannot buy a policy on you without your knowledge and consent — they must disclose the policy and get your signature.
Does insurable interest have to last until the person dies?
No. Insurable interest only has to exist when you buy the policy. If you buy a policy on your spouse and later divorce, you can keep the policy in force and remain the beneficiary. The policy does not become void just because the relationship ended.
What if I buy a policy and the person dies under suspicious circumstances?
The insurance company will investigate. They will look at the circumstances of the death, your relationship to the deceased, and whether you had a financial motive to harm them. If the death looks natural or accidental, the claim will likely be paid. If there is evidence of foul play and you are the beneficiary, the company may deny the claim and report the matter to police.
