Art. 744. All persons not disqualified by law may succeed by will or in the absence thereof.

Art. 756. The following are disqualified to succeed by reason of unworthiness:

1. Parents who have abandoned their children or prostituted their daughters or made attempts against their chastity.

2. He who has been sentenced in a trial for having made attempts against the fife of the testator, his spouse, descendents, or ascendants.

If the offender should be an heir by force of law, he shall lose his legal portion.

3. He who has accused the testator of a crime for which the law imposes an exemplary punishment, when the accusation is declared libelous.

4. The heir of age who, knowing of the violent death of the testator, has not denounced it to the courts within a month, unless the latter had already acted ex officio.

This prohibition shall cease in cases in which, according to law, there is no obligation to make an accusation.

5. A person sentenced at a trial for adultery with the wife of the testator.

6. He who by threats, fraud, or violence, forces the testator to make a will or to change it.

7. He who, by the same means, prevents another from making a will or from revoking one already made, or who forges, conceals, or changes a subsequent one.

Art. 757. The reasons for unworthiness shall produce no effect if the testator had knowledge thereof at the time of making the will, of if, having been informed of them subsequently, has condoned the same in a public instrument.
