Those who are already bound in marriage cannot contract a new marriage.
Persons who are twenty-three years of age or upwards may conclude marriage, if otherwise of legal capacity, without parental consent or advice.
Persons under twenty years of age require the consent of their parents, or of such persons whose right it is to give or withhold such consent.
Persons who are more than twenty years of age, but under twenty-three, are under the obligation of asking the advice or counsel of their parents or of such persons standing in the parental relation before contracting marriage, and if the advice is refused, or it should be unfavourable, the marriage cannot take place until three months after the petition was made.
The consent and the favourable advice for the celebration of a marriage must be proven, if requested, by means of an instrument authenticated by a civil or ecclesiastical notary or by the municipal judge of the domicile of the petitioner.
When the advice has been proven the lapse of time shall be proven in the same manner.
If a marriage is concluded by persons more than twenty years of age, and under twenty-three years of age, without compliance with the rules just stated, the marriage will be recognized as valid, but the offender is subject to certain disabilities and penalties.
Consanguinity and Affinity.—The following persons are prohibited from contracting marriage with each other:
1. The ascendants and descendants by legitimate or natural consanguinity or affinity.
2. Collaterals by legitimate consanguinity up to the fourth degree.
