If a document reflecting a change of cause of action has already been served on other parties, which option is correct to amend?

• A. Written consent of all other parties to amend
• B. Permission of the court
• C. Written consent of all other parties to amend or permission of the court
• D. No consent or permission is needed

Answer: (C)

When you want to amend a document that reflects a change of cause of action after it has already been served, you don’t get to do it unilaterally. The rule is that you may amend by either obtaining written consent from all other parties or by obtaining permission from the court. This dual pathway is what makes the option that includes “or permission of the court” correct: you can proceed if everyone agrees, or you can seek the court’s approval to proceed without everyone’s consent. If all other parties consent, no court order is needed. If not everyone consents, you must apply for the court’s permission, and the court will consider factors like whether the amendment is just, whether it would unfairly prejudice the other side, and whether the amendment fits the overall timetable of the case. The options requiring no consent or permission, or relying on consent alone, don’t fit after service because one of these routes must be available to proceed.
