If I am a transgender person, can I get married in Colombia?

Yes, transgender people can marry in Colombia just like any other couple. In fact, in the SU-214 judgment of 2016, the Constitutional Court analysed a case of a couple in which one of the partners was transgender and protected the couple's right to unite on equal terms. Denying marriage to a couple on the basis of the gender identity of one or both partners is discrimination. See question on requirements #3
