Point IV. On the Revocation of Testaments

833.
    • I. A testament, under whatever form it has been made, can always be revoked at the will of the testator, because a testament by its nature is an essentially revocable act; therefore the testator retains dominion of his goods up to death. - Thus from every law.

1 On the title above. Concerning another cause on account of which testaments are weakened, namely the passing over of children, see the Jurisconsults.

833.

II. Revocation of a testament can be made in a twofold way:

833.
  1. Expressly, or: 1. by destruction of the testament; 2. by an act drawn up before a notary, by which a change of will is expressed; 3. by a new testament contrary to the former. But then the revocation is not judged complete unless the dispositions of the new testament are contrary to all the dispositions of the former.
833.
  1. Tacitly, by donation, sale, exchange, destruction, or any disposition whatever of the thing bequeathed, by which the change of the testator is manifested 2.

2 Even with Gallic law considered, which the Author follows in this place, these things do not pertain to tacit revocation of a testament, but to the withdrawal of legacies.

833.

The lapse of a testament is referred to revocation of the testament; this is had when testamentary dispositions, although valid from the beginning, nevertheless become infirm because of certain circumstances: e.g. if the legatee dies before the testator, or before the execution of some condition, if the thing bequeathed perishes, etc.
