Family is the most basic unit in human society. Family is formed from its marital relation. Married couples are made by the combination of a man and a woman who try to lead their married life through their whole lifetime. Although the relation of married couples is formed to lead their married life, such married life can not be maintained only with conjugal affection, but should be essentially accompanied with its property relation as a economic problem. So, now, most countries prepare the systems and regulations on marital property relations.In China, there have been changes and developments in marital property system from ancient times through modern times to the contemporary period. In ancient times, under the influence of Jong Beop Je(Patriarchal System) and Confucian philosophy, extreme patriarchal family system was maintained, and so women's status was relatively low. In marital property relations, wives' property power had been also discriminated unreasonably until the western legal systems were introduced in the end of Qing Dynasty. Since the current government was established, the philosophy of gender equality has spreaded across the entire society, so that marital property system has been also developed pursuant to periodic flows. In the Chinese marriage law revised in 2001, the system of marital community property was adopted as the type of marital property system, and there were also many modifications on property division. During the abrupt revision of the marriage law, related regulations has been complemented in order to supplement the flaws of legislation.The current Chinese marital property system has been operated in accordance with the principle of gender equality, the principle of contract liberty, and the principle to protect the weak. First of all, if there are agreed contracts on their property relation between married couples, marital property relations are formed in accordance with such agreed contracts. Concluding the contracts on marital property is relatively free in their times and methods. Even if there are agreed contracts on their properties between married couples, such properties can be also divided in certain cases.On the other hand, if there are no agreed contract on their properties between married couples, legal property systems should be applied. Concretely, salaries and other incomes derived from production activities during marriage are regarded as marital community property to adopt marital community property system after marriage. In contrast, the damages according to physical injuries and the properties when there is a declaration of intention designating one party of spouses on a will or a donation are regarded as personal property to acknowledge individuals' separate(peculiar) property. The division of marital properties during marriage is also allowed.The division of property on divorce shows no large difference from other countries. Protecting women and children is the basic principle to divide properties on divorce. In addition, in spite of the agreed contract on marital property, the spouse who cared old people well can claim the division of property. Economic assistance can be granted to one party of spouses who is poor in living on divorce.The marital property system in China has undergone many changes through historical transformations. Sometimes, referring to the legislative cases in the Western countries regarded as the advanced countries of legal systems, China has arranged the legal system appropriate to China adopting socialist market economy system. However, there are defects in legal systems not to be adapted to rapidly changing social systems in China, or there occur problems contrary to the legal philosophy of the people not to overcome the traditional philosophy.Thus, the first purpose of this study is to begin by examining marital property system in the Chinese ancient times, and so discusses its historical developmental stages. The second purpose of this study is to largely classify the marital property system in the current Chinese laws concretely into the marital property system during marriage and the liquidation system of property relations on divorce. The third purpose of this study is to compare the Chinese marital property system with the Korean marital property system closely related to China historically and geographically.
