Terminating an LLC in California is a pretty simple affair. I wouldn’t blame you if this is the one thing you choose to DIY, since you can do it online. There are legal issues, though, in terminating an LLC or any entity. For example, you need to make sure that the LLC’s debts are paid or accounted for, including its taxes. And you’ll need the consent of a majority in interest of the membership. Having unanimous consent could cut the paperwork significantly.
