What about the responsibility at the legal level?

In the event of any legal action, for example in case of professional responsibility or non-fulfillment of a contract, the incorporation will also protect you. Indeed, it is then your business corporation that will be sued and will be answerable before the courts, and not you personally, the whole subject to a serious fault on your part. You can so protect your personal patrimony in the event of a judgment which is not favorable to you.
