The testator must have full civil capacity; The will must be the true expression of one's intention; 3. The testator must have the right to dispose of the property disposed of in the will; 4. The content and form of the will must be legal. 5. The testator signs and indicates the month and day. The grandson is not the legal heir. The maternal grandparents can only bequeath the property to the grandson. As the legatee, the grandson should make an expression of acceptance or renunciation of the bequest within two months after learning of the bequest.
