The key to defining premarital property is that the acquisition time of property is before marriage. If the property is acquired before the marriage registration, even if it is actually occupied after marriage, the property is also personal property before marriage. For example, if one of the spouses accepts inheritance before marriage, the inheritance will be divided after marriage. Although the inheritance is actually obtained after marriage, its ownership has been obtained before marriage, so it should be recognized as the premarital property of one party.
