Are you promoting a preexisting Corporation?
It is important to understand that prior to the formation of a corporation, there is someone that brings about the corporation and helps trigger the existence of the business entity.
This individual is called a promoter. A promoter engages in activities such as entering into the contract on behalf of the corporation. Their main objective is to bring the corporation into existence as a business entity via the articles of incorporation.
It is important to note that if you are a promoter, there becomes great responsible if and when you begin to act on behalf of the pre-existing corporation. A promoter becomes personally liable on behalf of the corporation if said promoter has actual knowledge of no corporation. So if there is no corporation and a promoter is acting on behalf of the corporation with the actual knowledge that there is no actual corporation, then he/she is jointly and severally liable for all liabilities created while acting.
Keep in mind that this rule is not absolute. If said corporation expresses an adoption of the contract and/or makes use of the benefits from the contract, then this may, in fact, relieve the promoter of liability.
Likewise, if the person with whom you are contracting with has actual knowledge that there is no incorporation, then you we are relieved from personal liability.
The general rule is that a corporation is not liable for preincorporation transactions entered in by the promoter. As a promoter, it is your duty to promote the business, but keep in mind that you have great risks and responsibilities if you are the only one that knows a corporation does not exist.
Nonetheless, a promoter is relieved from personal liabilities if said corporation adopts the contract you are entering in, or makes use of the benefits from the contract, or person with while you contract with is aware of non-existing corporation.
