Same-sex marriage has been legal in the Mexican state of Coahuila since 17 September 2014, based on an effective date established by legislation passed on 1 September 2014. Prior to the law's passage, civil unions for same-sex couples were legal, but not same-sex marriage. The passage of the same-sex marriage bill made Coahuila the second jurisdiction in Mexico, and the first state (as Mexico City is a federal district), to pass same-sex marriage via legislative means. Only Mexico City and the state of Quintana Roo allowed for same-sex marriage prior to Coahuila.
