Hello, old people can't write wills. It is also possible to let others write according to the real meaning of the old man and then the old man will copy it. As long as it is the true meaning of the elderly, the elderly can sign their names, then press their fingerprints and indicate the time. Then find three witnesses at the scene and ask them to sign at the bottom of the page: I certify the truth of the old man's will at the scene, indicating the place, witness, date and time. In this way, it is an effective will. If the answer is satisfactory, please accept the reply. thank you
