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

Under Article 37 of the Law on the Register of Deaths, Births and Marriages (2005), "medical certification" is required to attain legal gender recognition. However, there are no apparent criteria for what this "certification" must include or what level of medical intervention (if any) is required. Thus, in practice, the discretion lies with each individual registrar to accept or reject applicants. Before the change of gender marker is registered, the applicant must request a new EMSO (identification number).
According to ILGA-Europe, in January 2017, the Ministry of Internal Affairs published a circular establishing that applicants seeking legal gender recognition had to present a certified statement that they have undergone gender affirming surgery. However, after substantial advocacy efforts by local NGOs, including Legebitra, TransAkcija, and Amnesty Slovenia, the Ministry backtracked and published a new circular establishing that applicants had to submit a "certified statement" issued by a psychiatrist merely stating that they had "changed their gender" and indicating that the medical procedures leading to “gender change” are irrelevant for the legal gender recognition procedure, thus reinstating the interpretation that was in place before January 2017.
