Leftist politicians in Mexico considers issuing a marriage license, one that is only valid for two years.
"The proposal is, when the two-year period is up, if the relationship is not stable or harmonious, the contract simply ends," the Sydney Morning Herald quoted Leonel Luna, the Mexico City assemblyman from the Party of the Democratic Revolution who co-authored the bill, as saying.

The marriage contracts would include detailed provisions on how children and property would be divided up if the marriage ended at the two-year mark.
"Two years is the minimum amount of time it takes to know and appreciate what life is like as a couple," Lizbeth Rosas, another supporter of the proposed legislation, told BBC Mundo in Spanish.
"If you renew, that means you have an understanding with your partner, and that you are clear on the rules of the relationship."
Meanwhile, the conservative groups have reacted with dismay.
"At first I thought it was a hoax," Consuelo Mendoza, of the national union of parents, said. "These initiatives create a culture of disposability within important societal issues."
The Catholic Church has also criticized the proposal.
"This reform is absurd. It contradicts the nature of marriage," Hugo Valdemar, spokesman for the Mexican archdiocese, said.
"It's another one of these electoral theatrics the assembly tends to do that are irresponsible and immoral," he added.
