The Mexico City assembly is considering issuing two-year renewable marriage licenses, allowing couples to separate when the term expires rather than have to go through divorces.

“Leftists in the city’s assembly – who have already riled conservatives by legalizing gay marriage – proposed a reform to the civil code this week that would allow couples to decide on the length of their commitment, opting out of a lifetime,” reports the British daily newspaper the Telegraph. “The minimum marriage contract would be for two years and could be renewed if the couple stays happy. The contracts would include provisions on how children and property would be handled if the couple splits.”

“The proposal is, when the two-year period is up, if the relationship is not stable or harmonious, the contract simply ends,” said Leonel Luna, the Mexico City assemblyman who co-authored the bill. “You wouldn’t have to go through the tortuous process of divorce.”

Luna, a member of the leftist Party of the Democratic Revolution, which has the most seats in the 66-member chamber, says the proposed law is gaining support and he expects a vote by the end of this year.

Around half of Mexico City marriages end in divorce, usually in the first two years, reported the Telegraph.
