Gay and lesbian couples descended upon government buildings in Mexico City today to register for marriage licenses as Latin America’s first gay marriage law took effect. The first weddings will take place within a week to 10 days after the paperwork is processed.

Said the Associated Press:

“This is great, it is a feeling of relief, of celebration, everything,” said Daniel Ramos, 20, a medical student planning to marry his boyfriend, Temistocles Villanueva, on March 12.

“For Latin America, this is not only a precedent, but an example to follow,” he added.

For now the law applies only to residents of Mexico City, though a marriage performed in one Mexican state must be recognized in the rest of the country.

While activists are trying to get the law extended to the rest of Mexico’s 31 states, conservatives say they will seek to pass a constitutional reform so that other states won’t have to recognize marriages that do not conform to their laws.

For the time being, it appears easy to circumvent the residency requirement, because the city accepts a phone or utility bill as proof of address — often even if the bill is in someone else’s name.
