Certificate of Good Standing: What Is It & How It Works

Consider the following scenario: You’re the founder of a new startup, which you incorporated in Delaware, but you live in California. You need to register your company as a foreign entity to do business there. But before you can register in California, you’ll need to obtain a Certificate of Good Standing from your incorporated state of Delaware.
