1. Of minors under the age of 21 years, unless with parental consent. 2. Of persons of adult age who are incapable of properly governing themselves or their estates, without the authorization of their legal representatives. 3. Of an adulterous wife with her accomplice who has been condemned for the offence. 4. Of a wife who has been condemned as the principal or accomplice of the crime of homicide with a principal or accomplice in the same crime. 5. Of any person bound by solemn vows of religion to a life of chastity. The canon law of the Catholic Church defines the religious rules and spiritual effects of marriage, while the civil law defines the civil rules and temporal effects of the contract. A minister of the church who celebrates a marriage contrary to the requirements of Article 1058 of the Civil Code incurs criminal penalties. Marriage between Portuguese subjects who are non-Catholics is recognized as producing full civil effects. CONSANGUINITY AND AFFINITY.--The following persons are forbidden to marry each other: 1. Ascendants and descendants. 2. Persons related collaterally in the second degree. 3. Males who have not completed their fourteenth year and females who have not completed their twelfth year of age. 4. Persons already bound by marriage. Any infraction of these prohibitions makes a marriage voidable. MARRIAGE PRELIMINARIES.--Whoever desires to contract marriage according to the manner provided by the civil law of the land must present to the civil officer of the State acting in the place of the applicant's domicile a declaration setting forth: 1. The full names, ages, occupations and domiciles of the contracting parties. 2. The full names, professions and domiciles of the parents. Upon receiving this declaration the civil officer publishes a notice of the intended marriage and informs all interested persons to file their objections, if any exist, within fifteen days. If at the end of this period no valid objection to the marriage has been formulated the civil officer proceeds to the celebration of the marriage. CELEBRATION.--For the civil celebration of marriage the contracting parties, or their duly empowered proxies, appear before the civil officer of the commune, attended by competent witnesses. If the marriage is celebrated in the official bureau of the commune two witnesses are sufficient; if outside of such bureau six witnesses are required. Any civil officer celebrating a marriage contrary to these provisions incurs penal punishment. ANNULMENT OF MARRIAGE.--A Catholic marriage--that is, one solemnized according to the canonical law--can only be annulled by an ecclesiastical tribunal and according to the laws of the Catholic Church enforceable in Portugal. A sentence of an ecclesiastical tribunal annulling a marriage is executed by the civil authority of the land.
