Old people can't write, and the wills and signatures printed by old people should be valid. Although the Inheritance Law does not explicitly stipulate the legal effect of printing or copying wills in the form of testamentary achievements (but the law does not exclude its effect), many legal documents (such as contract achievements, indictments, power of attorney, notarized applications, etc.). There are printed forms in social life now, which can be signed by me for confirmation. The printed will shall be witnessed and signed by two disinterested witnesses, and the date shall be valid. The signature of the will printed in the civil code is valid, but certain conditions must be met. The condition stipulated in our country is that the witness must be an independent person, with at least two people. Secondly, after the completion of the witness, the year, month and day must be indicated.
