It is generally not possible to legally own a car but insure it in someone else's name. Most insurance companies require the policyholder to have an insurable interest in the vehicle, which means that they must have a financial stake in the car, such as owning it or having a financial investment in it. If you do not have an insurable interest in the car, it is unlikely that you will be able to purchase insurance for it.
There are a few exceptions to this rule. For example, if you are a co-owner of the car, you may be able to purchase insurance for it, even if your name is not on the title. Additionally, some insurance companies may allow you to purchase non-owner car insurance, which will cover you for liability while driving a car that is not yours. However, these policies typically do not provide comprehensive and collision coverage for the vehicle.
It's important to note that attempting to insure a car that is not in your name can complicate the claims process and may even be considered insurance fraud. It's always best to consult with an insurance professional to determine the best course of action for your specific situation.
