Yes, it is possible to purchase life insurance for your brother, but there are certain conditions and considerations to keep in mind. First and foremost, you must have insurable interest in your brother, which means you would suffer financially if something were to happen to him. This is a fundamental requirement for purchasing life insurance for another person. You will need your brother's consent to buy the policy and he may also need to undergo a medical examination as part of the underwriting process. The amount of coverage and the type of policy will depend on your brother's age, health, and financial situation. It's important to discuss this decision openly with your brother and consider consulting with a licensed insurance agent or financial advisor to understand the options available and the implications of purchasing life insurance for a family member. Keep in mind that the laws and regulations regarding purchasing life insurance for a sibling may vary by location, so it's advisable to seek professional guidance specific to your jurisdiction.
