A. Although Nonparty I signed as a witness in the notarial deed of this case, he did not act as a witness in the process of preparing the notarial deed of this case, Nonparty J, another witness, without the participation of the witness, is a will made without the participation of the witness, and the notary public does not have any fact that he reads the contents of the will to the witness.

Thus, the will by an authentic will of this case is null and void because there is a defect in the requirements of ① the participation of two witnesses among the requirements for preparation of an authentic will as stipulated in Article 1068 of the Civil Code, ② the notary public takes the demand of the testator and read it to the testator and the witness. Thus, the registration of ownership transfer based on the testamentary gift which the defendant completed with respect to each of the real property of this case is also null and void.

Therefore, the defendant is the plaintiff.
