If my car was stolen, can I cancel the insurance policy?

The legal implications I think that you are referring to would be your liability in the event that the party that stole the car got in to an accident of some sort or did some damage, correct?  The filing of the report should cover you there although your insurance company will always do an investigation in to the matter should it come to that.  What you need to do though is to take a look at your policy and see what it says about cancellation.  You may have to give a certain amount of notice.  You can also call your insurer, let them know that you want to cancel your policy and give them an effective date just so long as you comply with the notice requirement if any.  They will then send you a cancellation request form - review this form carefully before you sign and return it to your insurer.  Good luck.

You need to speak with your insurance agent as to whether you should cancel your insurance policy on your stolen vehicle or not. You have placed your carrier on notice about the theft and I understand why you do not want to pay for something you are not using. In speaking with your insurance representative about whether to cancel coverage or not on your vehicle, go over your concerns and ask for that person's advice on the subject and your carrier's custom and practice in such a situation.

Whatever you decide, follow up in writing with your representative as to what was said to you and your decision keeping a copy of the letter and or e mail for future need.

Good question.
