{{cite book}}: CS1 maint: location (link)We think it cannot now be controverted that an agreement between a man and woman to be husband and wife, consummated by cohabitation as husband and wife, constitutes a valid marriage unless there be in existence in the State in which the agreement is made, a statute declaring the marriage to be invalid unless solemnized in a prescribed manner. We think it equally true that the rule now generally recognized is that statutes requiring a marriage to be preceded by a license or to be solemnized by a religious ceremony without words of nullity as to marriages contracted otherwise are directory merely and failure to procure the license or to go through a religious ceremony does not invalidate the marriage. ... There is nothing in the statute which declares that a marriage shall not be valid unless solemnized in the prescribed manner, nor does it declare any particular thing requisite to the validity of the marriage. The act confines itself wholly with providing the mode of solemnizing the marriage and to the persons authorized to perform the ceremony. Indeed, the statue itself declares the purpose underlying the requirements to be secure registration and evidence of the marriage rather than to deny validity to marriages not performed according to its terms.
