Legal recognition of non-binary gender: Intersex only from Dec 22, 2022 to now.
The trans law mentions that when registering the birth of the intersex newborn, the mention of the sex can be blank for a maximum period of one year (it also prohibits surgeries for intersex people up to 12 years of age).
This recognizes the rights of Intersex people, but there is still no recognition of any non-binary identity in official documents.
