Gender self-determination: what it is and how it works

Gender self-determination is the principle that every person has the right to define their own gender identity and obtain documents consistent with it, without having to overcome medical, psychiatric, or judicial barriers. In a growing number of countries, this principle has been translated into laws that allow changing one’s legal gender through a simple declaration. In Italy, however, the process remains tied to a court proceeding that requires expert evaluations, lawyers, and lengthy timelines. Understanding what gender self-determination truly means — and what the data from countries that have adopted it show — is essential for an informed debate.

What is gender self-determination

Gender self-determination (also known as self-ID) is a legal model based on a simple idea: the person who best knows their own gender identity is the person themselves. In a self-determination system, anyone wishing to change the gender marker on their documents can do so through an administrative declaration, without needing psychiatric diagnoses, undergoing hormone therapy, having surgical procedures, or awaiting a court ruling [1][6].

This model is clearly distinct from two other historically prevalent approaches. The judicial model, adopted by Italy through Law 164/1982, requires a court to authorize vital records rectification based on medical and psychological evaluations. The medical model, still present in some countries, makes legal recognition conditional on a formal psychiatric diagnosis and, in some cases, sterilization or irreversible surgical procedures [1][3].

Self-determination does not mean that anyone can change their gender on documents “on a whim.” Laws that provide for it generally include procedural safeguards: a reflection period (from a few weeks to six months), the requirement of a formal declaration before a public official, and in some cases, the possibility of applying the procedure only from a certain age onward. What is eliminated is the medical-judicial filter, not the seriousness of the procedure.

The foundation of this approach lies in recognizing that gender identity is not a pathological condition to be diagnosed, but a fundamental aspect of a person to be respected. This view is consistent with the World Health Organization’s decision in the ICD-11, which came into effect in 2022, removing trans identities from the chapter on mental disorders and reclassifying gender incongruence as a condition related to sexual health [5].

The three models worldwide

To understand self-determination, it is helpful to compare it with other existing legal gender recognition models globally. According to the mapping by Transgender Europe (TGEU) and ILGA-Europe, legislative systems are divided into three main families [1][3].

The judicial model

In the judicial model, vital records rectification requires a court ruling. The person must file a petition, assisted by a lawyer, and submit medical and psychological documentation to the judge. In most cases, the court appoints an expert (court-appointed technical consultant) who examines the person and produces a report. Italy falls into this category. The process involves legal costs, timelines that can exceed two years, and inherent discretion: different judges, even within the same country, may reach opposite conclusions based on the same documentation [4]. This model is still present, with variations, in France, Greece, Romania, and several Eastern European countries.

The medical model

The medical model requires a formal psychiatric diagnosis as a necessary condition for document changes, but does not necessarily involve a court. In some countries, this model has historically included mandatory sterilization — a practice that the European Court of Human Rights has progressively declared incompatible with fundamental rights [7]. Even today, in several states, a diagnosis of gender dysphoria or gender incongruence remains an essential requirement. This approach treats trans identity as a medical condition to be certified, rather than a personal experience to be recognized.

The self-determination model

The self-determination model is based on the person’s declaration, collected by a public official (civil registry, notary, vital records office) without medical requirements. Procedures vary: Denmark requires a six-month reflection period, Spain requires a double appearance three months apart, Malta allows the declaration before a notary starting at age 16 [1][3]. In all cases, the principle is the same: the person decides, and the state takes note.

Pioneer countries

The history of gender self-determination worldwide follows a precise timeline, marked by countries that paved the way and a domino effect that involved a growing number of states.

Argentina (2012): the first law in the world

Argentina passed the Ley de Identidad de Genero (Law 26.743) on May 9, 2012, becoming the first country in the world to recognize the right to gender self-determination without any medical requirements [3]. The law defines gender identity as “the internal and individual experience of gender as each person perceives it” and allows any person to change their name, image, and sex on vital records through a simple request to the National Registry. No diagnoses, evaluations, hormone therapies, or surgical procedures are required. The law also guarantees free access to hormonal and surgical treatments for those who desire them, including them in the mandatory health plan. Over a decade after its implementation, Argentina’s experience is considered a model by international human rights organizations.

Denmark (2014): the first European country

Denmark was the first European country to adopt gender self-determination, with a law that took effect on September 1, 2014 [1]. The procedure involves a written request followed by a six-month reflection period, after which the person can obtain changes to their social security number, passport, and all official documents. In the first ten years of application, approximately 2,500 people used this procedure. No documented cases of system abuse have been recorded.

Malta (2015): the most advanced model

Malta adopted the Gender Identity, Gender Expression and Sex Characteristics Act (GIGESC Act) in 2015, approved unanimously by Parliament [1][3]. The law allows changing legal gender through a declaration before a notary starting at age 16, without any medical requirements. Malta was also the first country in the world to ban surgical normalization procedures on intersex minors without their informed consent. The Maltese model is often cited as the most comprehensive and advanced globally.

Ireland (2015) and Norway (2016)

Ireland passed the Gender Recognition Act in 2015, allowing gender change through a statutory declaration. Norway followed in 2016, with a law that allows changing legal gender starting at age 16 (and from age 6 with parental consent) through a simplified administrative procedure [1].

The European and worldwide timeline

After the pioneers, the model spread rapidly. Belgium (2017), Luxembourg (2018), Portugal (2018, revised in 2023), Iceland (2019) introduced self-determination-based procedures. Outside Europe, Uruguay (2018), Colombia (2015), Chile (2019), and New Zealand (2023) adopted similar laws [1][3]. Overall, by 2024, more than twenty countries worldwide recognize legal gender change without medical requirements.

The situation in Europe

The trans rights map in Europe, updated annually by Transgender Europe (TGEU), shows a divided continent [1]. On one hand, Western and Northern Europe has progressively embraced the principle of self-determination. On the other, Eastern Europe and parts of Central Europe maintain restrictive models, and in some cases have introduced actual regressions.

Recent progress: Spain and Germany

Two of the most significant recent advances involve Spain and Germany, two large European countries that adopted self-determination through ambitious legislation.

Spain passed the Ley Trans in February 2023, which allows people aged 16 and older to change their legal gender through a double appearance at the civil registry office, three months apart, without any medical requirements [2][3]. People aged 14 to 16 can access the procedure with legal assistance, while judicial intervention is required for those under 14. The law also introduced a ban on so-called “conversion therapies.”

Germany took a historic step with the Selbstbestimmungsgesetz (Self-Determination Act), passed by the Bundestag in April 2024 and taking effect on November 1, 2024 [1][3]. The law replaced the 1980 Transsexuellengesetz, eliminating the requirement for psychological evaluations and medical diagnoses. The procedure involves a declaration at the municipal registry preceded by a three-month waiting period. It is accessible to people from age 14. In the first two months of implementation, over 10,000 people changed their legal gender, compared to only 596 changes recorded in the ten months prior under the old law.

Those falling behind

Not all European countries follow this direction. Russia banned all forms of legal gender recognition in 2023. Hungary eliminated this possibility in 2020 [1]. In several Eastern European countries, document changes remain conditional on psychiatric diagnoses, prolonged hormonal treatments, and in some cases, surgical procedures. According to the ILGA-Europe annual report, polarization within the continent is increasing: while some countries advance rapidly, others regress [3].

The European Parliament has repeatedly called on member states to introduce rapid, transparent gender recognition procedures based on self-determination [2]. However, legislation on civil status matters remains a national competence, and European resolutions are non-binding.

The situation in Italy

Italy is one of the Western European countries that has not adopted the self-determination model. Legal gender recognition is governed by Law 164 of 1982, which requires a court proceeding before the ordinary court [4].

The current legal framework

Law 164/1982 establishes that sex attribution rectification is ordered by a court ruling. In practice, this means the person must: consult a psychologist or psychotherapist specializing in gender identity to obtain a psychodiagnostic report; be assisted by a lawyer to file a petition with the court; undergo, in most cases, a court-appointed technical evaluation (expert assessment) ordered by the judge; and await the ruling [4].

An important turning point came with Constitutional Court ruling No. 180/2017, which confirmed what the Court of Cassation had already established in 2015: gender reassignment surgery is not a mandatory requirement for vital records rectification [4]. The Court stated that the right to gender identity falls among the fundamental rights protected by Article 2 of the Constitution, and that imposing surgery as a condition for legal recognition constitutes an unreasonable restriction on personal freedom.

Problems with the current system

Despite the important jurisprudential evolution, the Italian system presents significant issues. Timelines for proceedings vary from six months to over two years, with profound disparities between courts in the North and South. Costs include legal fees for the lawyer, expert witness fees, and, when ordered, the court-appointed technical evaluation. Although legal aid is available for low-income individuals, the process remains burdensome for many people.

There is also a problem of discretion: in the absence of uniform criteria, each judge interprets the law according to their own orientation. Some courts systematically require expert evaluations, while others consider them unnecessary. Some judges adopt a restrictive approach, while others follow the most recent constitutional case law. The result is a system in which the outcome can depend on which court one goes to, creating a territorial inequality that is difficult to justify when dealing with a fundamental right.

Fears and actual data

Gender self-determination is the subject of recurring concerns in public debate. It is important to compare these fears with empirical data from countries that have adopted the model.

“There will be abuses”

The most frequent objection is that a declaration-based system would open the door to abuses: people changing gender on documents to obtain unfair advantages or access restricted spaces. Data from pioneer countries does not confirm this concern [1][3]. In Denmark, no documented cases of fraudulent use were recorded in the first ten years of the law’s application. In Ireland, government reports found no abuses. In Argentina, over twelve years after the law took effect, the number of people who used the procedure remained consistent with estimated transgender population figures. Self-determination laws, moreover, do not eliminate criminal law: any illegal behavior remains prosecutable regardless of a person’s legal gender.

“Regret will be widespread”

A second fear concerns the risk of hasty decisions and subsequent regret. Available data shows extremely low rates of detransition and regret, even in countries with self-determination. International scientific literature reports regret rates after legal transition generally below 2-3%. In Germany, the law provides a simple mechanism for returning to the previous situation, but requests to do so in the first months of implementation were negligible [5]. It is also important to distinguish between document changes — a reversible administrative act — and medical procedures, which are a separate and independent process from vital records rectification.

“Women will be less safe”

The argument that self-determination would compromise women’s safety in gender-segregated spaces (bathrooms, changing rooms, prisons, shelters) finds no support in the data [1][3]. In countries that have adopted self-ID, there has been no increase in assaults or violence in women’s spaces attributable to the law. Safety in these spaces depends on behavioral and criminal norms that remain unchanged, regardless of the gender recognition model adopted. Feminist organizations in several European countries, including Spain and Germany, have supported self-determination laws, recognizing that the rights of trans women and cisgender women are not in conflict.

What international institutions say

The principle of gender self-determination is supported by broad consensus at the level of international institutions and human rights bodies.

The Yogyakarta Principles

The Yogyakarta Principles, formulated in 2006 by a group of international legal experts and subsequently updated in 2017 with the YP+10, represent the first systematic attempt to apply international human rights law to gender identity issues [6]. Principle 31 of the YP+10 explicitly states that every person has the right to legal recognition of their gender identity without being required to meet medical requirements, including surgery, sterilization, or hormone therapy. The Principles also recommend that procedures be rapid, transparent, accessible, and based on self-determination [6].

Council of Europe Resolution 2048

In 2015, the Parliamentary Assembly of the Council of Europe adopted Resolution 2048, specifically dedicated to discrimination against transgender people in Europe [7]. The Resolution calls on member states to develop gender recognition procedures that are “quick, transparent, and accessible, based on self-determination” and to eliminate requirements for sterilization, mental disorder diagnosis, and medical procedures as prerequisites for legal recognition. Although Parliamentary Assembly resolutions are non-binding, they represent a significant political orientation for the 46 member states of the Council of Europe, including Italy [7].

Positions of the European Parliament and the United Nations

The European Parliament has adopted numerous resolutions calling on member states to ensure gender recognition procedures based on self-determination, defining them as a matter of fundamental rights [2]. In 2023, a specific resolution on the rights of LGBTI people in the European Union reiterated the need to eliminate medical and judicial requirements for legal gender changes [2].

At the United Nations level, the Independent Expert on protection against violence and discrimination based on sexual orientation and gender identity (IESOGI) has repeatedly recommended that states adopt self-determination-based gender recognition procedures, considering them the international standard most consistent with respect for human rights.

Scientific consensus: WPATH

The World Professional Association for Transgender Health (WPATH), in its Standards of Care version 8, published in 2022, stated that the depathologization of trans identities and access to legal gender recognition without medical barriers are associated with better mental health outcomes for transgender people [5]. The document emphasizes that making legal recognition conditional on psychiatric diagnoses perpetuates stigma and contributes to psychological distress, rather than alleviating it.

The impact on transgender people’s lives

Beyond the legal and political debate, gender self-determination has concrete and profound consequences on the daily lives of transgender people. Having documents that do not match one’s gender identity is not a bureaucratic inconvenience: it is a constant source of discrimination, humiliation, and danger.

The problem of non-matching documents

Every time a trans person must show an ID — at work, at the bank, at the doctor’s office, at the airport, when signing a contract, when picking up a certified letter — they are forced to reveal their personal history and expose themselves to the judgment, curiosity, or hostility of the other person [8]. This phenomenon, known as forced outing, strips the person of the right to privacy about their personal history and exposes them to discrimination in every area of life.

Concrete consequences

In the workplace, documents inconsistent with a person’s appearance can compromise a job interview, create embarrassment at the office, or provide a pretext for mobbing. In healthcare, presenting a health insurance card with a different gender than the one lived can lead to inadequate treatment, refusals of care, or privacy violations. During travel, discrepancies between physical appearance and passport data can generate invasive checks, interrogations, and in some countries, situations of concrete danger [8].

In countries with self-determination, these situations are eliminated or drastically reduced. The person can obtain documents consistent with their identity in a short time, without first having to complete a medical-legal process that can take years. This does not mean that medical transition becomes irrelevant — those who wish to access hormone therapy or surgery can continue to do so — but legal recognition of identity is no longer made conditional on a clinical pathway.

The effect on mental health

Scientific research shows a significant correlation between access to legal gender recognition and the psychological well-being of trans people [5]. A study published in The Lancet Psychiatry found that trans people who obtained documents consistent with their identity showed significantly lower levels of anxiety, depression, and suicidal ideation compared to those who were unable to do so. The WPATH Standards of Care confirm that legal recognition is a protective factor for mental health and that bureaucratic barriers to document changes contribute to minority stress — the chronic stress resulting from belonging to a stigmatized minority [5].

Conclusion

Gender self-determination is neither a privilege nor a concession: it is the recognition that every person has the right to be identified for who they are, without having to prove their identity before a judge or an expert. The Yogyakarta Principles [6], Council of Europe Resolution 2048 [7], European Parliament resolutions [2], and WPATH guidelines [5] converge on one point: self-determination-based legal gender recognition is the standard most consistent with respect for human rights.

Data from over twenty countries that have adopted this model shows that fears related to abuses, regret, and safety risks have not materialized [1][3]. On the contrary, self-determination has concretely improved the lives of trans people, reducing daily discrimination and contributing to their psychological well-being [5].

Italy, despite the important jurisprudential evolution of recent years [4], remains anchored to a judicial model that imposes timelines, costs, and a level of discretion that are difficult to reconcile with the protection of a fundamental right. Comparison with European countries that have already taken this step — from Denmark to Spain, from Portugal to Germany — highlights a gap that the Italian legislature has not yet closed. Gender self-determination is not a matter of opinion: it is a matter of human rights, and as such it deserves to be addressed with seriousness, data in hand, and respect for every person’s dignity.
