A new update to the Nintendo Account User Agreement prevents users from filing class-action lawsuits against the company.
With effect from May, 2025, the Nintendo Account User Agreement update has brought some important changes to how how customers and Nintendo will resolve disputes with one another through binding, individual arbitration, including a new requirement for informal dispute resolution before arbitration and new processes for coordinated filings. The updated version of the agreement can be found here.

Instead of going to court or joining a class-action lawsuit (where a group of people sues together), custmers now agree to handle disputes privately through a process called arbitration. This means:
- You can’t sue Nintendo in court.
- You can’t have a jury trial.
- You can’t join others in a class-action lawsuit or any group case.
- Any dispute must be handled individually, one-on-one, through arbitration.
This rule applies to any kind of legal issue between customers and Nintendo, regardless of whether it involves their use of Nintendo Account services or the terms of the agreement itself. However, users can choose to opt out of this arbitration rule. In order to accomplish this, they must send a written letter to Nintendo within 30 days of agreeing to the new terms. The letter must include:
- Your name
- Your contact information
- The email tied to your Nintendo Account
It must be mailed to: Nintendo of America Inc., Attn: CS Admin, 4600 150th Ave NE, Redmond, WA 98052.
Those who send the letter on time with all the required details won’t be bound by the arbitration rule, and they can still sue or be part of a group lawsuit if needed. If they don’t opt out, they automatically agree to the new arbitration rule.
It remains to be seen how Nintendo Account users will respond to this updated User Agreement, and whether it will be challenged in court.
