(3) A court may stay a proceeding commenced by a foreign corporation, its successor, or its assignee until it determines whether the foreign corporation, its successor, or its assignee requires a certificate of authority. If it determines that a certificate is required, the court may further stay the proceeding until the foreign corporation, its successor, or its assignee obtains the certificate.
