Can You Legally Buy Life Insurance on Your Adult Sibling?
Yes, you can buy life insurance on your adult sibling—as long as two key requirements are met:
- Insurable interest
- Your sibling’s knowledge and consent
These two rules protect everyone involved and ensure the policy is legitimate.
What Is Insurable Interest?
Insurable interest means you would suffer financially or emotionally if your sibling passed away.
Common examples include:
- You would pay for their funeral
- You share a mortgage or debt
- You co-own property or a business
- You want to avoid being burdened with final expenses
Fortunately, siblings are automatically recognized as having insurable interest in most cases, especially for final expense coverage.
Requirement #1: Your Sibling Must Consent
You cannot secretly buy life insurance on your sibling.
Your sibling must:
- Sign the application
- Agree to the coverage
- Answer health questions (if required)
The good news? Many modern policies make the process quick and stress-free.
