A lesbian couple on Saturday will become the first gay couple to marry in the Mexican state of Jalisco.

Zaira de la O and Martha Sandoval are planning to exchange vows before a judge in Guadalajara, the state's capital.

Last November, Jalisco lawmakers approved domestic partnerships for gay couples (Ley de Libre Convivencia), a union with limited benefits that is formalized before a notary, not a judge.

After being denied a marriage license in March, the couple sought relief from the courts and won, CNN Mexico reported.

“We are happy, relishing the moment we sign, with the same nerves as any couple about to marry for the first time,” Zaira said.

Much like the United States, Mexican states individually decide on marriage. Mexico City in 2009 became the nation's first, and so far only, municipality to legislatively approve marriage equality. Mexico's highest court declared the law constitutional and ordered all states to recognize the legal marriages of gay couples. However, only a handful of states have moved on the issue. Some, under court order, have allowed marriage, while others have adopted civil unions.

The women, who are raising a 1-year-old daughter, were represented in their legal fight by the Committee of Latin America and the Caribbean for the Defense of Women's Rights (Comite de America Latina y el Caribe para la Defensa de los Derechos de la Mujer, CLADEM).

CLADEM's Guadalupe Ramos said that she knew of at least five additional gay couples who want to marry in the state.

“What we hope is that we won't have to litigate in all of these cases to obtain the same rights as heterosexual couples,” said Zaira.
