You will only need a First Amended Summons if you are adding new defendants. Nevertheless, as a matter of good practice, you should always have a First Amended Summons issued in the event you want to add Doe defendants. However, you can always have a First Amended Summons issued at a later date when it becomes needed.

Mr. Chen is correct. Unless you have other defendants who have not yet formally appeared in the case, you do not need a first amended summons.
