The parties (shareholders/partners) establishing the company enter into a contract titled “Articles of Association (AoA)”. Every company is required to have an AoA which is legally binding on the company and all of its shareholders and which can be regarded as its internal rules, prepared by the shareholders. The AoA cannot contain rules that are against the law. AoA of a company must be in a written form and should bear the signatures of all the shareholders, authenticated by the notary public.
