Legal analysis: (1) Notarization of will. A notarized will is a will that the testator has processed through a notary office. Notarization of a will is the most stringent method of will, which can ensure the authenticity of the testator's expression of intention. Notarization of a will is also the most reliable evidence for handling will and inheritance disputes.

(2) Self-written will. A will written by the testator himself is called a self-written will. A self-written will is when the testator expresses his or her wishes in writing.

(3) Writing a will on behalf of others. A ghostwritten will is a will written by someone else. Writing a will is usually a last resort when the testator cannot write or is unable to write due to illness. However, in order to ensure that the will written by the ghostwriter is indeed the true intention of the testator and reduce disputes, it should be witnessed by two or more witnesses. One of them should write on his behalf, indicating the year, month and day, and the scrivener, Other witnesses present and the testator sign the will on behalf of others.

(4) Recorded will. A taped will is a will dictated by the testator that is recorded on a tape recorder. Recorded wills can easily be forged and edited. Therefore, the law stipulates that a will made in recorded form must be witnessed by two or more witnesses to prove the authenticity of the will.

(5) Oral will. An oral will is a will that is expressed orally by the testator and not recorded in any way. The testator can only make an oral will in critical circumstances, and it must be witnessed by more than two witnesses. After the critical situation is resolved, if the testator is able to make a will in written or recorded form, the oral will will be invalid.
