Can you get auto insurance if the auto is in a collection agency?

If you are planning on getting the vehicle back and reaffirming your finance note then "Yes". You can buy insurance for it. You will probably be required to do so in order to get it back from the collection agent. If you are not planning to redeem the vehicle then you are considered to have surrendered the vehicle, You no longer have a financial interest in the vehicle and therefore can not legally insure it
