A marriage between a male person of sixteen and a female of fourteen years of age is valid, but if either party has not attained the age thus fixed, the marriage is a nullity or not at the option of such party made known at any time before he or she is six months older than the age thus fixed. [§3377.] The common law rule fixing the age of consent to marriage at fourteen for males and twelve for females is not repealed in Iowa. The time in which the parties may disaffirm the marriage is merely extended by the statute.
Previous to any marriage within this state, a license for that purpose must be obtained from the clerk of the district court of the county wherein the marriage is to be solemnized. [§3378.] As under the common law, no express form or ceremony is necessary to constitute a valid marriage, any mutual agreement between the parties to assume the relation of husband and wife, followed by cohabitation, being sufficient, provided there is no legal disability on the part of either existing at the time. It is immaterial how the intention to marry is expressed. It has been held in this state that a marriage was legal, where the woman intended present marriage, though the man did not, where they had assumed the relation of husband and wife, and his conduct had been such as to justify her in believing that he had intended present marriage. Marriages by consent only, are not rendered void by a provision punishing parties for solemnizing marriages in any other manner than that prescribed by law.
Such license must not in any case be granted where either party is under the age necessary to render the marriage absolutely valid, nor shall it be granted where either party is a minor, without the previous consent of the parent or guardian of such minor, nor where the condition of either party is such as to disqualify him from making any other civil contract. [§3379.]
Unless such clerk is acquainted with the age and condition of the parties for the marriage of whom the license is applied for, he must take the testimony of competent and disinterested witnesses on the subject. [§3380.]
He must cause due entry of the application for the issuing of the license to be made in a book to be procured and kept for that purpose, stating that he was acquainted with the parties and knew them to be of competent age and condition, or that the requisite proof of such fact was made known to him by one or more witnesses, stating their names, which book shall constitute a part of the records of his office. [§3381.]
