7. Pregnancy by wife, at the time of marriage, by another than her husband, without husband's knowledge. 8. Conviction and imprisonment for a felony. NEW YORK. MARRIAGE.--Marriage is a civil contract, to which the consent of the parties capable in law of making the contract is essential. Minors become capable of contracting marriage upon completing their eighteenth year of age. A marriage is void from the time its nullity is declared by a court of competent jurisdiction if either party thereto was under the age of eighteen at the time it was concluded. IMPEDIMENTS.--Marriage between an ancestor and a descendant, between a brother and sister, of either the whole or half blood, between an uncle and niece, or an aunt and nephew, whether the relatives are legitimate or illegitimate, is incestuous and void. The defeated party in an action of divorce against whom a decree has been granted on the grounds of adultery is prohibited from marrying again during the lifetime of the successful party. However, the court which granted the decree has power so to modify it as to permit such marriage after five years. COMMON LAW MARRIAGE.--By an act which became effective April 12, 1901, the law of New York has required a contract of marriage to be signed by the parties and witnesses acknowledged and recorded. Since that time a "common law" marriage, or one established simply by cohabitation and reputation, has not been recognized. MARRIAGE LICENSES.--The legislature of New York, at its session in 1907, passed an act providing for marriage licenses, which became effective January 1, 1908. Written consent of both parents or guardian must be given to the town or city clerk before he may issue license. If residents of the State, they must personally appear and execute the consent; if non-residents, it must be executed, acknowledged and certified. WHO MAY SOLEMNIZE MARRIAGE.--A clergyman or minister of any religion, or the leader, or the two assistant leaders, of the Society for Ethical Culture in New York City, justices and judges of courts of record, judges of the county courts, justices of the peace, mayors, recorders and aldermen of cities. MARRIAGE BY CONTRACT.--A lawful marriage may be concluded by a written contract of marriage signed by both parties, and at least two witnesses who shall subscribe the same, stating the place of residence of each of the parties and witnesses and the date and place of marriage, and acknowledged by the parties and witnesses in the manner required for the acknowledgment of a conveyance of real estate to entitle the same to be recorded. Such contract shall be filed, within six months after its execution, in the office of the clerk of the town or city in which the marriage was solemnized. JEWS AND QUAKERS.--Marriages among Quakers or Jews may be solemnized in the manner and according to the regulations of their respective societies.
