我国《继承法》规定,遗嘱有自书遗嘱、代书遗嘱、录音遗嘱、口头遗嘱和公证遗嘱5种形式。公证遗嘱是公证机构对当事人所立遗嘱的真实性、合法性所作的证明。其优点有三:一是法律效力优于其他形式的遗嘱。在《继承法》规定的五种遗嘱中,前四种形式的遗嘱不得撤销、变更公证遗嘱;在立有数份遗嘱的情况下,应以立遗嘱人最后所立的公证遗嘱为准。二是能够保证当事人所立遗嘱符合法律规 China’s “Inheritance Law” provides that wills have five forms of will, book will, tape testament, verbal will and notarized will. Notarial wills are notarised by the notary office as to the authenticity and legality of the will of the parties. There are three advantages: First, the legal effect is superior to other forms of will. Of the five wills stipulated in the Succession Law, the first four wills may not be revoked and the notarial wills changed; in the case of a number of wills, the last will of the testator shall prevail. The second is to ensure that the parties will make a will consistent with the law
