New York Consolidated Laws, Domestic Relations Law - DOM § 12. Marriage, how solemnized

No particular form or ceremony is required when a marriage is solemnized as herein provided by a clergyman or magistrate, but the parties must solemnly declare in the presence of a clergyman or magistrate and the attending witness or witnesses that they take each other as husband and wife.  In every case, at least one witness beside the clergyman or magistrate must be present at the ceremony.

The preceding provisions of this chapter, so far as they relate to the manner of solemnizing marriages, shall not affect marriages among the people called friends or quakers;  nor marriages among the people of any other denominations having as such any particular mode of solemnizing marriages;  but such marriages must be solemnized in the manner heretofore used and practiced in their respective societies or denominations, and marriages so solemnized shall be as valid as if this article had not been enacted.
