Limited liability companies represent trading companies in which one or more legal or natural persons invest the main roles. With these roles, one or more legal entities have the possibility to participate in the share capital, which has already been agreed upon earlier. All limited liability companies must consist of at least one member of the board (manager or director). The aforementioned is important because the scope or competence of the assembly and the supervisory board does not include the possibility of managing affairs or the appropriate representation of the company. The supervisory board must have at least three members, with the number of members always being odd. The number of members of the supervisory board is determined by the social contract. The members are given full freedom in this, but it is not possible for the supervisory board to have only one member. If the social contract does not contain a provision on the number of members of the supervisory board, it should be assumed that the board has three members. As a rule, the supervisory board is an optional body in a limited liability company, unless there are assumptions when it is mandatory. This, bearing in mind the assumptions of obligations, is an exception, so the majority of limited liability companies do not have to have a supervisory board. When there is no obligation, the supervisory board can be established in a limited liability company and then it can have the same position (depending, of course, on the specific case) as if it were a mandatory body. The Supervisory Board supervises the management of the company's affairs. The supervisory board can review and examine the company's business books and documentation, treasury, securities and other things. For this purpose, the board can use some of its members or experts. The Supervisory Board gives an order to the auditor to examine the annual financial reports of the company and concern.
