Can my partner or I get in trouble for having sex if we aren’t married?
Maybe.
Even if you and your partner both agree to have sex, sex with a minor is illegal under California law unless the two people are married.
Marriage and relationships
If I’m emancipated, do I need my parent’s permission to marry?
Yes. If you are under 18, you still need the same permissions.
If I got married in another state or country, am I married in California?
Yes.
If your marriage is legal in that state or country, California law says you are married.
