The reason why the mysterious events happen is that the deceased does not detail his own property allocation in the future at the time of birth. Since the law-seeking affairs office of the society deals with the heritage at present involves certain cost and time, many people do not want to spend the money, and the parties in the interests of the heritage are finally in the book hall due to the respective interests, and spend a lot of money for the heritage. Such behaviors are completely not conducive to economic development of society and result in a waste of legal resources.
Even if the departed person finds out the testimonial advice which is dealt with by the law firm, the situation that two different law firms claim that the testimonial advice of the departed person is held by the law firm but the content is greatly different can be avoided, so that the social prosperity of the luxurious offspring and the billions of the deceased can be avoided. The law firm manages files, and for the person who sets up the testimonial advice, the law firm cannot prevent whether the lawyer executes the testimonial advice after setting up the testimonial advice or whether the original intention is changed by modifying the testimonial advice.
The standing will not be conscious of the young people in east and west, and in case of unfortunate accidents, the family may not know the property information of the deceased. Especially in globalization today, many people store assets in different countries or buy financing products in different areas, and once the departed has not been handed over with the data, the property will not be appreciated finally, and the value of the asset is lost. In addition, properties such as digital assets and the like are stored in the cloud through various account passwords, and even if a successor knows the storage place of the assets, the successor cannot know the private key, namely, the properties become a string of numbers which can not be seen. The implication of key security is not resolved if the password inheritance is handled through conventional lawyer files or hard disk storage.
