The object of property publication isn't property alteration but property itself.Whether the property has been publicized or not cannot exert any direct influence on the validity of property alteration.The basic function of property publication is only to display the new static ownership of property after the property alteration has already occurred.They are different questions at different levels.There are lots of important differences between them in many aspects,such as the institutional goal,the institutional value,and the factors which should be considered throughly.So the property publication can be and should be separated from the property alteration.This kind of separation has been displayed obviously in both real property and personal property.Based on this,the problem characteristic of the selection of property alteration mode changes.The function of property alteration mode is to give a scientific and reasonable time criterion for property alteration between the parties concerned if they cannot reach a special agreement.
