Art. 738 Unincorporated association; members

If you want to sue a group like a club, nonprofit, or other organization that isn't officially incorporated, you can sue that group directly using its own name. You don't need to track down and sue every single member individually just to hold the group accountable.

This rule also gives you another option. You can sue the individual members of the group together if the debt or obligation belongs to the whole association. And if you choose to go this route, you can still include the association itself as a defendant in the same lawsuit. This gives people who are owed something more flexibility in deciding who to name in their case, whether that's the organization itself, its members, or both.
