No particular form for the ceremony of marriage is required, but the parties with legal capacity to contract marriage must declare, in the presence of the person solemnizing the marriage and of two witnesses of legal age, that they take each other as husband and wife. This declaration shall be set forth in an instrument in triplicate, signed by signature or mark by the contracting parties and said two witnesses and attested by the person solemnizing the marriage.
In case of a marriage on the point of death, when the dying party, being physically unable, cannot sign the instrument by signature or mark, it shall be sufficient for one of the witnesses to the marriage to sign in his name, which fact shall be attested by the minister solemnizing the marriage. (3)
