The Uruguay Parliament is expected to give final approval on Wednesday to a bill which seeks to legalize gay marriage in the nation.

The Uruguay Senate overwhelmingly approved the measure earlier this month and sent it back to the lower house, which approved it in December. A second vote is needed to approve changes made to the bill in the Senate.

Modifications made in the Senate are not considered controversial and the legislation is expected to easily clear the lower house (la Camara de Diputados).

The “Marriage Equality Law” seeks to modify some 20 articles of the Civil Code, including whose surname goes first when children are named.

“It will be a very broad and generous law,” LGBT activist Omar Salsamendi told the AFP. “And I think it will leave the country at the head of nations that grant such rights.”

Salsamendi, a journalist who married his husband Federico Macerattini in Buenos Aires last year, said the couple was making plans for a second wedding, this time in Uruguay.

“We got married in Buenos Aires for love, not activism,” he said. “We met and decided to start a family. As soon as the law is in effect we plan on marrying here.”

President Jose Mujica has said he'll sign the bill into law.

If the marriage law is approved, Uruguay would become the 12th nation to legalize such unions. In South America, only Argentina has extended marriage to gay couples. But inroads are being made in several other countries, including Mexico and Brazil. Colombia is currently debating the issue.
