The founders of a company are free to choose the form of the company they are about to be. In some cases, the law prohibits certain activities to companies that have not chosen a specific form. Thus, an insurance company can not choose the form of SPRL. Similarly, if a person wants to be a single company, it can not choose the form of a limited company.

When building the company, the founders should consider all types of companies and find one that best suits the chosen and the objectives they seek activity: A society that seek greater participation of its members choose the form cooperative. One that will launch in public savings will choose the anonymous form. By cons, for family businesses, the founders probably prefer BVBA.
