Can a minor car accident with no damage cause a judgment to be made against you?

A judgement is a court order that makes you responsible to pay for damages or for a bill that the court deems you responsible for. If you have a minor accident with no damage then there will be no reason to place a judgement against you.

While the foregoing is generally true, the definition of "minor" is up for grabs. For example, if the collision resulted in the need for a side-view mirror to be replaced, a few hundred dollars could be involved between parts and labor. That may not be minor to the person whose car was hit.

Furthermore, a judgment is not "made" against you. As indicated in the original answer, a judgment results from a judicial (court) proceeding, and you would have to have been found to be At Fault for causing the damage ("negligent"), Further, you would have to have been served with a summons and complaint so that you know that you were being sued, and given the chance to defend the claim. If, for example, you did not appear at a hearing or file a response to the lawsuit (whichever is required in your jurisdiction), a default judgment can be entered against you. While service of the summons and complaint is often made by a sheriff, in some jurisdictions, service by certified or registered mail is allowed. Therefore, if you did not pay attention to the mail, you would not have known of the court date or otherwise what was required of you. Finally, in some jurisdictions, and often with respect to auto collisions, the law permits "constructive" service of process. This requires that the plaintiff conduct a diligent search for you and try to effect customary service of process. If that effort fails, in some jurisdictions, the law allows that service of process can be made on the motor vehicle authority (a government authority that regulated drivers and drivers licenses).
