Hello, I'm lawyer Luo from An Law Firm. I know that my will is valid as long as there are no other invalid circumstances. Wills are divided into oral wills, self-written wills, agency wills and notarized wills, and their application situations are different. The will may not need to be witnessed by a lawyer (private certificate) or notarized, but it can better determine the authenticity and legitimacy of the will if witnessed or notarized by a lawyer. There is also the printing of wills according to your father's wishes, and the form of wills signed by your father is not clearly stipulated by law at present. Generally speaking, if it is dictated by your father, it will be defined as a self-made will, but the writing form has changed because of the popularity of computers. If your father didn't dictate it, it's a will written on behalf of him and needs the signature of a witness.

The answer I gave you is accurate, but the legal problem is not that simple. Don't be reluctant to pay the lawyer's consulting fee or lawyer's fee and leave trouble. I suggest you find a local lawyer with a lawyer's license to learn more.
