Call the court and see if they have anything on file with your name/casr number/whatever other identifying info from the notice. It may be a scam and they're hoping you call whatever number is on the notice and try to "settle it" by giving your credit card info

If you call the actual number and theres nothing on file...all good. If there is something on file you'll probably need to show up and prove it's not you they're after.
