Article 1 of the Constitution of Mexico was amended to prohibit discrimination based on, among other factors, sexual orientation.

The congress of Mexico’s northeastern border state Tamaulipas has voted to recognise same-sex marriage, making it legal across the country.

Becoming the last of the country’s states to do so, Tamaulipas amended the state’s Civil Code on Wednesday, setting off cheers of “Yes, we can!” from supporters of the change.

In Mexico, there are no laws restricting to discussion or promotion of LGBTQ+ topics.

In 2009, the Supreme Court of Mexico established in its Judgment No. 6/2008 (2009) that the right to personal identity and free development of personality includes the right to gender identity and to "sexual reassignment", which obliges states to provide access to the "rectification of name and sex legal markers".
In 2018, the Court issued Judgment No. 1317/2017 (2018) where it analysed the most appropriate procedure to guarantee "sex-gender rectification in the Civil Registry". In summary, this judgment concluded that the type of authority (judicial or administrative) before which the procedure is conducted is irrelevant as long as the nature of the procedure is materially administrative. Specifically, it must (a) be comprehensive; (b) be based on free and informed consent, with no medical, psychological and/or pathologising requirements; (c) be confidential; (d) be expeditious and free of charge; and (e) it must not require surgical or hormonal treatments. Despite this, various Mexican have not unified their regulations and, in many cases, continue to require judicial processing and all sorts of evidence.

Non-binary Mexican citizens can choose to have an X as their gender marker rather than choosing male or female.

However, other IDs are handled on a state level basis and not all of them allow the X gender marker.

Since 2011, Article 1 of the Political Constitution of the United Mexican States (1917) (federal constitution) prohibits discrimination based on “sexual preferences”. 3 out of 32 subnational jurisdictions bans discrimination based on gender identity in its State Constitutions. Article 1(3) of the Federal Act to Prevent and Eliminate Discrimination (2003) includes “sexual preferences” as one of the prohibited grounds of discrimination

Most of Mexico's states have enacted laws that ban discrimination based on sexual orientation or sexual preference, as well as gender. Many states also explicitly ban discrimination based on gender identity in local laws.

At the level of the federal government authorities, Article 1(3) of the Federal Act to Prevent and Eliminate Discrimination (2003) includes “sexual preferences” as one of the prohibited grounds of discrimination. This law applies to housing as per Article 9(XXI). Gender identity is not explicity mentioned

There is no federal law allowing for joint adoption and second parent adoption by same-sex couples. Adoption is only permitted for same sex married couples in 21 of the 31 Mexican states and Mexico City
