Pet animals in Mexico City will no longer be considered “things” in civil processes. As a result of a reform unanimously approved by the Mexico City Congress, they will now be recognized as sentient and conscious beings.
This legally obligates individuals to ensure their well-being. The measure was endorsed in an extraordinary period with 55 votes in favor, through an amendment to the Civil Code for the Federal District, which included Article 855 BIS.
“Every person has the legal obligation to respect the life of animals and ensure their well-being, according to the needs and biological characteristics of each species,” the text states.
Mexico, animal rights, and a historic change in the Civil Code
The new rights of pet animals in Mexico City.
The Chapter II of Title IV of Property was also modified and is now called “Of animals”, instead of “Of the appropriation of animals”. This change reflects a new paradigm in the relationship between people and their pets.
During the legislative discussion, Deputy Yuriri Ayala (Morena) highlighted that this is “a legal advancement that will transform the way we relate to animals”, recalling that both the Constitution of Mexico City and the Supreme Court of Justice of the Nation already recognized them as sentient beings.
On the other hand, Elvia Estrada (PVEM) pointed out that the reform is “an act of justice and humanity”, recalling that in 2024, 54% of the complaints to the Environmental Prosecutor and Land Management (PAOT) were related to cases of animal abuse.
Similarly, Diana Barragán Sánchez (PT) emphasized that the legal recognition implies a moral imperative and a clear message: “the left protects life in all its forms”.
Shared custody of pets in divorce cases
In the same session, the Mexico City Congress approved another amendment to the local Civil Code: in divorce proceedings, pets may have shared custody. In this way, their care and well-being are sought to be guaranteed, avoiding being treated as mere material goods.
When does the change take effect?
The decision was sent to the Government Head, who must publish it in the Official Gazette of Mexico City. Once published, it will come into effect immediately, consolidating Mexico City as a reference in animal rights and protection in Latin America.
