Marriage, as a union between a woman and a man, is one of the most complex legal and life institutes, consisting of emotional, personal and property relations, and this complexity is also reflected in the division of marital property that occurs as a result of the termination of the marital union. Although the Family Law Act introduced the institute of marital property, pursuant to which property is divided in equal parts, the problem represents determining what is marital property and what is one's own property. Since business shares represent a set of membership rights and obligations and are not property in the classic sense of the word, the situation is even more complex. Within this set of rights and obligations, spouses can be jointy authorized persons, pursuant to the Companies Act, what has also been confirmed by the case-law. The determination that the business share represents marital assets does not solve the problem, because the determination does not result in the division of that share, nor is the same possible through legal proceedings, for the reason that division requires the consent of the authorized person on the business share and the decision of the company's assembly.
