Art. 29. Birth determines personality, but the conceived child is considered as born for all favorable purposes, provided that it be born with the conditions mentioned in the following article:

Art. 30. For civil purposes the foetus shall only be considered as born which has a human form and lives twenty-four hours entirely separated from the mother's womb.

Art. 31. Priority of birth, in case of twins, gives to the first born the rights which the law recognizes in primogeniture.

Art. 32. Civil personality is extinguished by the death of persons.

Minority, insanity, or idiocy, the state of being deaf and dumb, prodigality, and civil interdiction are only restrictions upon the judicial personality. Those who are in any of these conditions may have rights and even obligations when they arise from the facts or from the relations between the property of the incapacitated person and a third person.

Art. 33. Should there be doubt between two or more persons called to succeed each other as to which of them died first, he who alleges the prior death of one or the other must prove it; in the absence of proof it shall be presumed that they both died at the same time, and the transmission of rights from one to the other shall not take place.

Art. 34. With regard to the presumption of the death of an absentee and its effects the provisions of title 8 of this book shall govern.
