It has been legal since 1988 but the current criminal code was enacted in 2000.

"The judges affirmed by a majority that marriage between people of the same sex does not violate the constitutional order," judge Maria Victoria Calle said.

In Colombia, there are no laws restricting the discussion or promotion of LGBTQ+ topics.

In response to two rulings of the Constitutional Court in 2015, the Colombian Government issued a decree on 4 June 2015 to simplify the process by which adults over 18 can legally change their gender. The decree, signed by the Ministry of Justice and the Ministry of the Interior, says the gender change is justified by a person's individual choice; it eliminates the requirement for psychiatric or physical examinations.

The Constitutional Court of Columbia ruled that a non-binary person was entitled to a birth certificate and identity card with a "no binario"/"NB" sex marker.

Sexual orientation is explicitly covered in the law. Gender Identity on the other hand, is not mentioned explicitly but is implied.

Article 134A of the Criminal Code (2000), as amended by Law No. 1,482 (2011), criminalises discrimination based on "sexual orientation", while Article 136C (3) and (4) aggravate the penalty if such discrimination is committed by public servants or while providing public services.
These provisions ban "sexual orientation" discrimination in broad terms and therefore apply to employment. Article 136C (6) also includes the motive of denying or restricting labour rights as an aggravating factor.

Added to the previous factor we have ruling SU440-21 from the Constitutional Court of Colombia. The Colombian Supreme Court "Corte Constitucional de Colombia" decided on December 9, 2021 based on ruling SU440-21 that transgender people in Colombia cannot be discriminated against due to their gender identity when receiving state financial pensions, despite the decision to have as its object the receipt of state financial pensions, the sentence in its paragraph 55, section III makes it clear that the principle by which this decision was taken is that gender identity is protected by the general constitutional clause of article 13 of the Constitution of Colombia making it clear that discrimination based on gender identity is prohibited in other areas, which includes housing and employment discrimination.

Article 134A of the Penal Code (2000), amended by Law No. 1,482 (2011), criminalizes discrimination based on "sexual orientation", while Article 136C (3) and (4) increases the penalty if such discrimination is committed by public servants or during the provision of public services.
These provisions prohibit discrimination based on “sexual orientation” in general terms and therefore apply to employment. Article 136C (6) also includes the reason for denial or restriction of employment rights as an aggravating circumstance.

Added to the previous factor we have the SU440-21 decision of the Colombian Constitutional Court. The Colombian Supreme Court "Corte Constitucional de Colombia" ruled on December 9, 2021 based on decision SU440-21 that trans people in Colombia cannot be discriminated against due to their gender identity when receiving financial pensions from the State, despite the ruling of having as its object the receipt of financial pensions from the State, the sentence in its paragraph 55, section III makes it clear that the principle by which this decision was taken is that gender identity is protected by the general constitutional clause of article 13 of the Constitution of Colombia, making clear that discrimination based on gender identity is prohibited in other areas, which includes discrimination in housing and employment.

The Colombian Ministry of the Interior released a presidential decree in spring 2016 that provides a broad policy of procedural obligations for government institutions and territorial entities in relation to LGBTI rights. The document calls for the creation of an Intersectoral Commission to Guarantee the Rights of the LGBTI Community (Spanish: Comisión Intersectorial para la Garantía de los Derechos de la comunidad LGBTI). The decree specifically addresses the rights of LGBTI Colombians in public education, health care, prisons and as victims of armed conflicts. The text clarifies that “national entities cannot refuse to recognize that a same-sex couple can form a family and, consequently, enjoy the constitutional protections and equal opportunities provided to other families”.

In May 2018, President Juan Manuel Santos issued an executive decree ordering the Ministry of the Interior to continue guaranteeing the rights of LGBT people in the social sector, namely in health, education, work, housing, recreation, sport and culture, as well as establish support programs. Therefore, this decree serves as a prohibition of housing and employment discrimination at the state level, reinforcing previous jurisdiction and legislation.

Previously couples could only adopt a child if it was from one of the partners, but the same-sex adoption law allows homosexual couples the same rights as heterosexual couples.

Sentence T-099 of the Colombian Supreme Court exempted trans women from mandatory military conscription, but did not deprive them of serving in the military if they wish, this option is also valid for trans men. It is also worth highlighting that there has never been any impediment to the military service of homosexual and bisexual men and women.

The age of consent in Colombia is 14 for people of all sexual orientations.
