Article 12
ARTICLE 12. Simultaneous death. — If, as between two or more persons who are called to succeed each other, there is a doubt as to which of them died first, whoever alleges the death of one prior to the other shall prove the same; in the absence of such proof, it is presumed that they died at the same time and there shall be no transmission of rights from one to the other. However, the successional rights of their respective heirs shall not be affected.
