How to take legal action against contracts signed under duress
Read the complaint and summons.
When you are served with a lawsuit for breach of contract, you'll receive a summons, which tells you when and where to appear in court and how long you have to respond. The complaint contains the factual allegations against you.
Check the court where the plaintiff filed the lawsuit. If it's far away, you may have an argument that the court doesn't have personal jurisdiction over you.
