What happens if the pleadings leave out some important facts?
The pleadings can be changed during the legal action if the other party agrees. If the other side does not agree, the court may still give permission to change the pleadings. When the parties reach a trial, they are restricted to the details in the pleadings when they argue their case. The judge may allow them to change an item that is not very important or if it would cause an injustice not to allow the amendment. Normally a judge will not allow a detailed change at such a late stage if, for example it changed the whole nature of the case. It would not be fair to the other side.
