FAMILY.CODE
SECTION 300-310
300. (a) Marriage is a personal relation arising out of a civil
contract between a man and a woman, to which the consent of the
parties capable of making that contract is necessary. Consent alone
does not constitute marriage. Consent must be followed by the
issuance of a license and solemnization as authorized by this
division, except as provided by Section 425 and Part 4 (commencing
with Section 500).
(b) For purposes of this part, the document issued by the county
clerk is a marriage license until it is registered with the county
recorder, at which time the license becomes a marriage certificate.
301. An unmarried male of the age of 18 years or older, and an
unmarried female of the age of 18 years or older, and not otherwise
disqualified, are capable of consenting to and consummating marriage.
