Questão jurídica principal
Whether the testamentary addition was void because it lacked place, date, and signature.
Decisão extraída
The absence of place and date did not make the addition void; the signature issue did not lead to nullity because the addition was proven to originate from the testator.
Fundamentação extraída
Under the amended succession rules, place is no longer required and date only in certain cases. A missing signature can be fatal only in cases of complete absence, not where an added text is inserted under an existing signature and proven to be by the testator.
