The revocation and the breaking of a will prevent it from having its legal effects. The revocation is the will of removing the effectiveness of a previously elaborated testament, since the testator has proved capacity to take that decision. The revocation can be total or partial; it can also be expressed, when the testator declares that he is invalidating, when the content of a previous testament is incompatible with the one resulting in settling the previous one. The breaking of a will is a form of legal revocation of the will that occurs when the testator disposed of the available part of his assets as he wishes, however, an heir arises that the testator was not aware of when he formulated the will.
