If you're actually being sued, you will receive a complaint and summons. However, there are glaring jurisdiction and venue issues.
If you don't receive a summons and complaint, then don't worry about a lawsuit, because there isn't one. But just to be on the safe side, I would contact the clerk of the court to see if there is an action pending.
If you do receive a complaint and summons, your best option is to hire a lawyer.
However, if you can't afford a lawyer, you should probably file a "limited" answer addressing only the jurisdiction and venue issues.
In a nutshell, in order for a case to be conducted in a given court, three things are needed: personal jurisdiction over the defendant; subject matter jurisdiction over the claim; and proper venue.
The court lacks personal jurisdiction over you if you don't live within its geographical boundaries or the transaction didn't take place within its geographical boundaries. The court lacks subject matter jurisdiction over the claim if it doesn't involve federal law or the claim is for less than $25,000. The court is a proper venue only if you live within its boundaries, the transaction took place within its boundaries, or you agreed via contract that it would be a proper venue.
If I were you, I would file an answer that does not address any of the allegations in the complaint. Rather, I would merely state that the court 1) lacks personal jurisdiction over you; 2) lacks subject matter jurisdiction over the Plaintiff's claim; and 3) that the court is not the proper venue for the Plaintiff to bring the claim.
Again, if you are actually sued, your best option is to hire a lawyer.
Best of luck!
