Can You Register A Car With Someone Else's Insurance? 
If you are a listed driver on the policy and the car is on the policy and you live in the same house hold this is possible with some carriers . However If you are not living with them and they are just putting your car and you not listed as a driver then there could be some issues . A person can not insure something the do not have insurable interest in . So If you are having a friend put the car on their policy just so you can register it then that would not be the case . As always check with your state laws and the insurance carrier as to what guidelines they have .
