Virtually all insurance companies allow you to extend the Civil Liability of your policy with the Voluntary Civil Liability modality, a recommended insurance for large families. This covers the damage that the rest of occupants of your vehicle may cause to a third party. For example, if your child throws an object through the window and it hits the car behind you, your insurance will be liable for the damage caused, but if you do not have this guarantee, you will have to pay for the repair.
Decide if you want third party insurance or all risk. If the car is new, the best is a risk. But a complete third party is a good option. If you choose a risk, decide if you want it with or without franchise. With franchise the price of insurance will be reduced. You will only pay the franchise if you are guilty or there is no guilty party for sinister.
Keep in mind if it is a new or used vehicle, if you use it regularly or sporadically, also if a new person is going to drive it. In the case of the minivan, it is convenient that you do not lose sight of the fact that it is a family car. It is a car that will be surrounded by children and therefore is more likely to receive scratches and unintentional blows from children. Open the door too strong or not fixed, and grate it without realizing it. They are small family accidents more common than you think
