Section § 410.50

Explanation

This law explains that a court has control over a person involved in a lawsuit once that person is notified of the case, or if they voluntarily join the lawsuit. This means that the court's authority over the people involved and the topic of the lawsuit continues as the case progresses.

Section § 410.70

Explanation

This law states that when you sue multiple people who are responsible for a contract together or separately, the court can decide the case against those who have been properly notified, even if not everyone involved has been notified.

In an action against two or more persons who are jointly, jointly and severally, or severally liable on a contract, the court in which the action is pending has jurisdiction to proceed against such of the defendants as are served as if they were the only defendants.
