Legal analysis: invalid. Making a will is a citizen's own business, and no one can interfere with it, let alone let the testator make a will against his will by deception or coercion. A will must be the true meaning of the testator, and no one may coerce or deceive him to make a will against his will, otherwise it will not be protected by law and will be invalid.
Legal basis: Article 143 of the Civil Law of People's Republic of China (PRC), the will made by a person without or with limited capacity for civil conduct is invalid. A will must express the true meaning of the testator, and a will made by fraud or coercion is invalid. Forged wills are invalid. If the will is tampered with, the tampered contents are invalid.
