A bill that would strike the traditional definition of marriage from California law is advancing through the Legislature after the U.S. and state Supreme Courts allowed same-sex unions to resume.

The state Senate approved the bill Thursday to remove language from the state Family Code saying marriage must be "between a man and a woman."

The bill would substitute gender-neutral language, define marriage as a personal relation arising from a civil contract between two people, and remove limits on the state recognizing same-sex marriages performed outside of California.

It now heads to the Assembly.
