The legal division of property due to the invalidity of personal testament means that the testament is invalid due to the lack of legal knowledge. At this time, the estate needs to be divided according to legal procedures.
Article 22 of the Inheritance Law states that wills made by persons without or with limited capacity are invalid. A will must express the true will of the testator, and a will made under duress or deception shall be invalid. A forged will is void. If a will is tampered with, the tampered contents shall be invalid.
