It is possible to take out a life insurance policy on someone else, including a family member such as a grandmother. However, there are certain conditions and considerations to keep in mind. First, it's important to have insurable interest in the person you want to insure, meaning you would suffer financially if they were to pass away. Second, you would typically need the consent of the person you want to insure, including your grandmother, to take out a policy on their life. Third, the person being insured may need to undergo a medical examination or provide medical records as part of the underwriting process. Fourth, the amount of coverage and the cost of the policy may depend on the age and health of the person being insured. Fifth, it's important to consider the potential tax implications of taking out a life insurance policy on someone else. It's advisable to consult with an insurance agent or financial advisor to understand the specific requirements and implications of insuring your grandmother or any other family member. They can provide personalized guidance based on your individual circumstances and needs.
