One of those things about False Accusations are that no matter how false they seem to you, in a court of law they might not appear as false to the next person.
You will be a defendant in the court and thus you have to take all the necessary actions that the law mandate you to. Most state laws will require you to file an answer or alternatively you can file a demurrer which is more technical and you might need an attorney for help.
It is always a good idea to seek legal support, at the very least – take a small counseling session with a lawyer and prepare a roadmap on how to proceed with this.
Naturally, being a law-suit – it will start with a summon. The details of the summons will include the case number and give you more information on how to file a response. At this moment, it is best to just sit down and read it out very carefully. The legal terms are always difficult to understand so perhaps getting some legal advice to clear things up, might be a good idea.
The next step requires you to submit your answer, the form to do so is usually available in any of the court’s website. Do note that filing an answer is very important and there is always a deadline which is mostly less than 30 days. Failing to do so will mean that you are absent which can result in an un-due advantage for the other party. They can request the court to make a judgement against you.
So, make sure to attend it and be well prepared.
