It is certain that the transfer of ownership cannot be handled directly by the notarial deed of will. A notarization of a will may be made in multiple copies or may be revoked, and the last will shall prevail. The notary said that the housing registration department could not judge whether it was the final will if it only took a notarization of will to request the transfer of ownership.
 Therefore, the beneficiary of the will needs to take the notarization of the will to the notary office to apply for inheritance. The notary asked all the heirs whether there were any other wills in their hands to determine that the will held by the beneficiary was the last or only one. It is an effective way to protect the legitimate rights and interests of other legal heirs to ask whether other persons with inheritance rights have other wills. For example, people who lack the ability to work are an important group.
