Overview

Over the past fifteen years, the law on sex and gender identity has moved in two directions at once. In the 2010s a wave of countries, starting with Argentina in 2012, let people change the sex recorded on their birth certificates and identity documents by simple declaration, with no medical diagnosis, hormones or surgery. In the 2020s many legislatures and courts began to look again: some put sex back into the legal definitions of "woman" and "man", some banned legal sex change outright, and others kept self-declaration but added waiting periods, age limits and reviews.

This page sets out what changed, where and when, as of October 2026. It covers legal gender recognition (the procedure for changing the sex on official documents), legal definitions of sex, single-sex spaces, prisons and sport, "conversion therapy" bans, and the laws that matter most to detransitioners: whether a document change can be reversed, how long people have to sue, and who pays for detransition care. Youth medical transition policy is covered in depth on evidence reviews and international policy and only summarised here. For the underlying concepts, see the parent page, sex vs gender identity in law.

Laws in this area change quickly and several cases were still in court when this page was written. Where a status could not be confirmed from a recent source, the page says so.

In this section

Four pages go deeper:

• Sex and gender identity law in the United Kingdom: the Gender Recognition and Equality Acts, Scotland, the For Women Scotland ruling (the 2025 UK Supreme Court decision that "sex" in the Equality Act means biological sex), prisons, sport and schools.
• Sex and gender identity law in the United States: federal rules and court cases, state laws, and laws written specifically for detransitioners.
• Sex and gender identity law in Europe: European court rulings, the self-ID wave and the reversals, country by country.
• Changing legal sex back after detransition: whether and how a legal sex change can be reversed, jurisdiction by jurisdiction.

Key terms

• Legal gender recognition (LGR): the process by which a state amends the sex or "gender marker" on a birth certificate, ID card or passport.
• Medical model: recognition requires a diagnosis of gender dysphoria and often hormones, surgery or sterilisation.
• Self-identification (self-ID) or self-determination: recognition by declaration, sometimes with a short waiting or "reflection" period.
• Certificated sex: the UK term for the sex a person has under a Gender Recognition Certificate (GRC), as opposed to their biological sex.
• Sex-definition laws: statutes that define "sex", "male", "female", "man" and "woman" by reproductive biology for all or most purposes of a jurisdiction's law.

Timeline of major changes

Country comparison

The table summarises the position in selected jurisdictions as of October 2026. "Not confirmed" means no recent primary or reliable source was found for that point.

Europe

The self-determination wave

Denmark was the first European country to allow a legal sex change without a medical statement, from September 2014: applicants over 18 declared that they belonged to the other sex and waited out a six-month "reflection period" (Library of Congress 2014). Ireland (2015) followed with a statutory declaration of a "settled and solemn intention" to live in the preferred gender (Library of Congress 2015), then Malta and Norway, which also opened the process to children: in Norway, from age six with parental consent (AP via CGTN). Belgium removed all medical conditions from January 2018 (Belgian Federal Justice).

Finland's 2023 reform abolished a sterilisation requirement that had stood since 2002 and replaced psychiatric assessment with self-declaration after a 30-day wait (International IDEA). Spain's Law 4/2023 lets anyone over 16 change the sex on their ID by attending the civil registry twice, three months apart, where previously a diagnosis and two years of hormones were needed (Le Monde). Germany's Self-Determination Act replaced the 1980 Transsexuals Act, which had required two psychological reports and a court decision, with a registry declaration from 1 November 2024 (German Federal Foreign Office). TGEU, a trans advocacy organisation, counted Germany as the 12th European country with self-determination (TGEU, advocacy).

Not every country went the whole way. Sweden, the first country in the world to allow a legal sex change (1972), passed a new act in 2024 that took effect on 1 July 2025: it lowers the age to 16 with guardian consent and simplifies assessment, but its main trans advocacy group notes it "does not fully represent self-determination" (RFSL, advocacy; Sweden.se).

Second thoughts in Germany and Spain

Germany's law quickly became politically contested. The centre-right CDU/CSU's 2025 election programme promised to abolish it; the coalition it then formed with the centre-left SPD instead agreed to evaluate the law in 2026, with a focus on the protection of women and children (Queer Nations; CDU). The case of Marla Svenja Liebich, a convicted far-right extremist who changed registered sex under the law, led the federal interior minister and the states of Saxony, Saxony-Anhalt and Thuringia to call for amendments to prevent "obvious misuse" (beck-aktuell, June 2026). Whether the evaluation has led to amendments could not be confirmed as of October 2026.

In Spain, the regional assembly of Madrid partly repealed its own trans protections in December 2023 after the national law passed (SIT study). The national Ley Trans itself remains in force.

Bans and reversals

A separate group of countries moved the other way:

• Hungary (2020): Section 33 of an omnibus bill replaced "sex" in the civil registry with "sex at birth" and stated that once recorded it "cannot be amended". The Constitutional Court later ruled that the ban did not apply to applications already under way, and in 2023 upheld the ban itself (Human Rights Watch, advocacy; Verfassungsblog).
• Russia (2023): a July 2023 law bans "medical interventions aimed at changing the sex of a person" and changes of sex in official documents and public records (Le Monde).
• Georgia (2024): the Law on Family Values and Protection of Minors restricts medical procedures that alter a person's sex and the designation of gender in official documents (JURIST).
• Slovakia (2025): a constitutional amendment passed on 26 September 2025 recognises only two sexes, male and female, and asserts national sovereignty over "cultural-ethical questions" (AP via PBS). Reports also describe tighter conditions on changing sex; how these are applied in practice could not be confirmed.
• Bulgaria: a 2023 interpretative decision of the Supreme Court of Cassation effectively ended legal gender recognition (ILGA-Europe, advocacy). This is now being reversed under EU law (below).
• Turkey: a draft "11th Judicial Package" published in October 2025 proposed raising the minimum age for sex reassignment from 18 to 25 and criminalising conduct "contrary to biological sex" (Türkiye Today). Whether these provisions became law could not be confirmed.

The European courts

European courts have pulled in the opposite direction from Hungary and Slovakia. In Mirin (October 2024) the Court of Justice of the EU (CJEU) held that a member state must recognise a change of name and gender made in another member state (Ristuccia and Marcia 2025). In Deldits (March 2025) it held that the right to correct inaccurate data under the GDPR (the EU's General Data Protection Regulation) covers gender markers, and that Hungary could not demand proof of surgery (European Law Blog). In March 2026 it went further, ruling that Bulgaria must provide a recognition procedure for a citizen living in Italy (JURIST); Bulgaria's top court followed in September 2026 (Los Angeles Blade). These rulings set up a direct conflict with Slovakia's claim that national law prevails in such matters.

United Kingdom

The Gender Recognition Act and the Scottish bill

The UK never adopted self-ID. Under the Gender Recognition Act 2004 an adult needs a diagnosis of gender dysphoria, evidence of two years living in the "acquired gender" and a declaration of intent to do so until death; a panel decides. By 2018 only 4,910 certificates had been issued (UK Government consultation, 2018). Most UK documents, including passports and driving licences, can be changed without a GRC.

In December 2022 the Scottish Parliament passed the Gender Recognition Reform (Scotland) Bill, removing the diagnosis, lowering the age to 16 and cutting the required period to three months (Guardian). In January 2023 the UK government used section 35 of the Scotland Act for the first time to stop the bill going for Royal Assent, arguing it would affect the operation of UK-wide equality law. The Court of Session upheld the order on 8 December 2023 and the Scottish government did not appeal (Institute for Government).

For Women Scotland and the EHRC code

On 16 April 2025 the UK Supreme Court ruled unanimously in For Women Scotland Ltd v The Scottish Ministers that "sex", "man" and "woman" in the Equality Act 2010 refer to biological sex, so a GRC does not change a person's sex for equality-law purposes (Matrix Chambers; Kennedys). Gender reassignment remains a separate protected characteristic. Critics argued that the court heard from gender-critical interveners but not from trans organisations (Völkerrechtsblog).

The Equality and Human Rights Commission's revised code of practice for services, laid before Parliament on 21 May 2026, came into force on 5 August 2026. It states that single-sex toilets and changing rooms should be used according to biological sex, while providers should offer practical alternatives such as gender-neutral facilities (Guardian; Hill Dickinson). More than 100 MPs signed a motion to disapprove it (PinkNews). An updated employment code had not been finalised as of the sources reviewed.

In June 2026 the Court of Session applied the ruling to prisons, finding unlawful the Scottish Prison Service guidance that let some trans-identified male prisoners be held in women's prisons. The Scottish government did not appeal and began moving prisoners according to sex (BBC). In England and Wales, a 2022 policy already kept trans women with male genitalia or sexual convictions out of the general women's estate, with a small number held on a separate wing at HMP Downview, a women's prison in Surrey (UK Parliament written answer, 2025).

North America

United States: federal

On 20 January 2025 Executive Order 14168 declared it federal policy "to recognize two sexes, male and female", defined by reproductive cells "at conception", and directed that passports and other federal IDs reflect sex rather than gender identity (Executive Order 14168). The State Department stopped issuing "X" markers and changes away from birth sex. A Massachusetts court blocked the policy in Orr v. Trump, but on 6 November 2025 the Supreme Court stayed that injunction, reasoning that displaying sex at birth is like displaying country of birth, "merely attesting to a historical fact" (US Supreme Court). Existing passports remain valid until they expire. The First Circuit heard the appeal on the injunction in June 2026; the litigation was continuing at the time of writing (FindLaw).

Executive Order 14201 (5 February 2025) directs enforcement of Title IX against schools that allow males in girls' and women's sport (Congressional Research Service). In United States v. Skrmetti (18 June 2025) the Supreme Court upheld Tennessee's ban on puberty blockers and hormones for minors, leaving similar laws in more than 20 states intact (KFF).

United States: states

States diverge sharply. Kansas passed the first "Women's Bill of Rights" in 2023, defining sex as biological sex at birth by reference to reproductive systems (Poynter). Iowa removed gender identity from its civil rights act and ended birth-certificate changes from 1 July 2025 (Jackson Lewis; Iowa Public Radio). Utah, West Virginia and Wyoming followed (Ogletree), then Texas (HB 229, from 1 September 2025) (Rubin Fortunato) and North Carolina (HB 805, from 1 January 2026) (QNotes).

Some states have gone back over documents already issued. Texas's attorney general issued an opinion in March 2025 directing agencies to "immediately correct" earlier sex-marker changes (OutSmart). Kansas's SB 244, in force from 26 February 2026, invalidated more than a thousand driver's licences and birth certificates whose sex marker differed from birth sex, requiring holders to surrender them (Topeka Capital-Journal); a challenge was pending in state court (ACLU, advocacy). At the other end, many states let people change their documents by self-attestation and offer an "X" marker.

Canada

Canada's federal ban on conversion therapy (2022) is discussed below. Alberta passed three laws in December 2024 restricting medical transition for minors, requiring parental consent for name and pronoun changes at school and limiting female sport to people recorded female at birth; in November 2025 it invoked the notwithstanding clause of the Canadian Charter of Rights and Freedoms (which lets a legislature override some Charter rights for up to five years) to shield them from court challenges (Egale, advocacy; CityNews). Provincial rules on changing the sex on birth certificates were not reviewed for this page.

Latin America

Latin America led the first wave. Argentina's 2012 Gender Identity Law allows anyone 18 or over to change their registered sex on the basis of their "self-perceived" identity, with minors acting through their legal representatives (Law 26.743). Brazil's Supreme Court ruled in March 2018 (ADI 4275) that name and sex can be changed at a civil registry without surgery, hormones, medical reports or a court (STF). Uruguay's comprehensive 2018 law (Law 19.684) simplified registry changes and guaranteed access to hormones and surgery (IMPO). Chile's law took effect in December 2019: adults can change by an administrative procedure and 14- to 17-year-olds through a court (Washington Blade). Colombia (2015) and Costa Rica are also usually counted among self-determination countries (Cambridge University Press).

There has been little reversal of legal recognition in the region. The main shift has been medical: in April 2025 Brazil's Federal Council of Medicine banned puberty blockers for minors and hormones before 18 (see evidence reviews).

Asia-Pacific

New Zealand moved to self-identification for birth certificates on 15 June 2023: a statutory declaration to the registrar replaced the Family Court process, and a "non-binary" marker was added (Department of Internal Affairs). Regulations allow additional requirements for people who apply more than once (Regulatory impact statement). The current coalition has not repealed self-ID. A bill from a member of the New Zealand First party defining "woman" as "an adult human biological female" passed its first reading on 20 May 2026 and was before a select committee at the time of writing (RNZ).

Australia handles birth certificates at state level. Queensland's change without surgery took effect in June 2024 and New South Wales passed similar reform in October 2024 (QNews; ABC). Federally, Tickle v Giggle went the opposite way from the UK. In August 2024 the Federal Court found that a women-only app had unlawfully discriminated against a trans woman. In May 2026 the Full Court upgraded the finding to direct discrimination and doubled damages to A$20,000, and on 10 September 2026 the High Court refused leave to appeal. Under the Sex Discrimination Act 1984, excluding a trans-identified male from a women-only service on the basis of gender identity is therefore unlawful unless an exemption applies (Human Rights Law Centre, advocacy; Guardian; ABC).

Elsewhere in Asia:

• Japan: the Supreme Court struck down the sterilisation requirement in October 2023, but sent back to a lower court a separate requirement that genitals resemble those of the other sex (Reuters).
• Hong Kong: in February 2023 the Court of Final Appeal held that full sex reassignment surgery cannot be required to change the sex on an identity card (Reuters).
• India: the 2019 Act recognises a right to "self-perceived gender identity" through a "transgender" certificate, but a change to male or female requires surgery (PRS India). For historical context, see India's hijra.
• Pakistan: the 2018 Act's self-perceived identity provisions were struck down by the Federal Shariat Court in May 2023, which held that gender must conform to biological sex; an appeal was announced (DW).

Africa and the Middle East

Change here has been slower and less documented. Many countries in both regions have no procedure for changing legal sex, and this page did not review them in detail. Iran is an exception: it permits and funds sex reassignment, but only with surgery and within a framework critics link to pressure on gay men (see Iran). Turkey's draft restrictions are described above.

Single-sex spaces, prisons and sport

• Spaces: in Great Britain, single-sex services are now defined by biological sex under For Women Scotland and the 2026 EHRC code. In Australia, Tickle points the other way. In the US the answer depends on the state; Kansas, Texas, Utah and West Virginia have laws restricting facilities by sex (ACLU of Kansas, advocacy; EPS).
• Prisons: Scotland moved to housing prisoners by sex in June 2026 after a court ruling; England and Wales use a presumption against placing trans women with male genitalia or sexual convictions in the general women's estate (above). US federal policy follows Executive Order 14168.
• Sport: World Aquatics (June 2022) limited the women's category to trans women who had not gone through male puberty beyond Tanner stage 2 (the first physical signs of puberty) or age 12 (CNN). World Athletics required a one-time SRY gene test for the female category from 1 September 2025 (Lexology). In March 2026 the IOC adopted the same approach for Olympic events from Los Angeles 2028, replacing its 2021 framework, which had left eligibility to each federation (Reuters). Sports physicians had criticised that framework for leaving federations without clear standards (Pigozzi et al. 2022). Alberta's Fairness and Safety in Sport Act limits female amateur sport to those recorded female at birth (Xtra).

Conversion therapy bans and exploratory therapy

Laws against "conversion practices" matter to detransitioners because they shape what therapists feel able to say to someone who is questioning a transition, or a detransition. Most of them cover gender identity as well as sexual orientation and expressly exempt support for transition:

• Victoria, Australia (2021): the Change or Suppression (Conversion) Practices Prohibition Act carries penalties of up to 10 years' imprisonment. It states that a practice is not a change or suppression practice if it "is supportive of or affirms" a person's identity, including "assisting a person undergoing or considering undergoing a gender transition" (Lexology; HRLA). The Australian Medical Association and the Royal Australian and New Zealand College of Psychiatrists warned during drafting that the law was too broad (HRLA).
• Canada (2022): Bill C-4 created criminal offences from 7 January 2022 (Library of Congress). The Criminal Code excludes practices that relate to gender transition or to "exploring" a person's identity without favouring a particular outcome (Egale, advocacy).
• New Zealand (2022): the Conversion Practices Prohibition Legislation Act makes conversion practices on under-18s, or causing serious harm, a crime. It exempts health practitioners acting within professional standards and assisting someone "undergoing, or considering undergoing a gender transition" (Human Rights Commission guidelines; Library of Congress).
• England and Wales (draft, 2026): a draft Conversion Practices Bill was published on 25 June 2026 for pre-legislative scrutiny. Ministers said it includes "an exemption in the Bill for all healthcare professionals" to avoid a chilling effect (Hansard). Christian and gender-critical groups have criticised its breadth (Christian Medical Fellowship).

The structure is asymmetric. These laws name helping someone toward transition as a protected activity, but none of the texts reviewed here names helping someone stop or reverse a transition. Exploratory therapy is protected in Canada only if it does not favour an outcome, and in New Zealand through the professional-judgement exemption. In practice, many detransitioners believe these laws stop therapists from questioning a gender identity at all, even where the text does not say so. That belief, accurate or not, can itself shape practice. See gender exploratory therapy and the support directory for therapists who work this way.

National evidence reviews and the resulting restrictions are covered in detail on evidence reviews and international policy and puberty blockers. In brief:

Trends: the 2010s wave and the 2020s re-assessment

Why self-ID spread

Supporters of self-ID saw the medical model as degrading and invasive. Sterilisation requirements in particular came to be seen as a human rights violation and were struck down by courts in Sweden, Japan and elsewhere. Advocates argued that a diagnosis should not be needed to live one's life, that documents matching appearance reduce harassment, and that there was little evidence of misuse. Ireland's 2015 law passed with little public debate; even a critical account notes there was "no consultation with the general public" (Genspect, advocacy). Much of the early wave moved through low-salience administrative reform and court rulings rather than public campaigns.

Why the re-assessment came

Several pressures converged in the 2020s:

• Conflict with sex-based rights: once "woman" includes anyone with a certificate or declaration, rules on women's prisons, refuges, sport and lesbian associations become contested. The UK Supreme Court found a certificated-sex reading would make the Equality Act incoherent; Australian courts, applying a differently written statute, reached the opposite result.
• Changing patient population and evidence reviews: the rise in adolescent referrals, mostly of girls, and the systematic reviews that followed undermined confidence in the medical pathway that legal recognition had once been tied to (Cass 2024).
• High-profile misuse cases: Germany's Liebich case and prison placements in Scotland became focal points.
• Detransition: the growing visibility of people who changed their documents and then wanted to change them back exposed how the systems had been built.
• Political realignment: in Russia, Hungary, Georgia and Slovakia, restrictions came packaged with "traditional values" and anti-Western politics and also targeted same-sex couples. In the US they arrived through executive orders and partisan state legislatures.

On the other side, trans advocates and many human rights bodies see the 2020s changes as a rollback driven by political opportunism, which leaves trans people with documents that out them and exposes them to harassment. European and Australian courts have continued to expand recognition. The result is not a single global trend but a divergence: the same year (2026) saw Kansas invalidate changed birth certificates and the EU's top court order Bulgaria to start issuing them.

What it means for detransitioners

Changing documents back

Detransitioners who changed their legal sex face very different situations depending on where they did it and when they want to reverse it. A few laws address reversal explicitly:

• Spain: a person may return to their original sex after six months by the same procedure; any further change requires a judge (European equality law network). The registrar must explain the possibility of reversal at the first appearance (EUWONDER).
• Germany: a declaration can be reversed, but not within one year of the previous change (German Federal Foreign Office).
• Finland: repeat changes are reportedly limited to once a year, a rule linked to military service (LGBTQ Nation).
• Argentina: once made, a registry change "sólo podrá ser nuevamente modificada con autorización judicial" (can only be changed again with judicial authorisation) (Law 26.743, Art. 8).
• Ireland: a GRC holder who wants to revert can apply to revoke it on form GRC 3, in a process "similar" to the original application (Citizens Information).
• New Zealand: regulations may impose additional requirements on second and later applications (Regulatory impact statement).
• United Kingdom: the Gender Recognition Act has no reversal mechanism. Its criteria (a diagnosis of gender dysphoria, two years living in the "acquired gender") fit a detransitioner returning to their birth sex poorly (UK Government 2018).
• United States: the federal passport policy makes restoring birth sex simple. State rules vary widely: some states allow only one change without a court order, while Kansas and Texas now treat birth sex as the only valid entry.
• Russia and Hungary: bans written to stop transition also stop people from changing back.

The paradox is that both directions of reform can trap detransitioners. Liberal regimes often treat a second change as suspicious, adding court orders or waiting periods. Restrictive regimes may refuse any change at all, including a return to birth sex. In the US, by contrast, the 2025 federal policy and some state sex-definition laws make reversal easier, which some detransitioners welcome and others find uncomfortable. Practical guidance on names, documents and coming out is on social and practical detransition.

Limitation periods and lawsuits

Medical negligence claims usually have short deadlines. North Carolina's absolute cutoff of four years from the last treatment ended the malpractice claim of detransitioner Prisha Mosley in 2024. HB 805, enacted on 29 July 2025 over Governor Stein's veto, gives anyone injured in the course of gender transition, at any age, 10 years from discovering the injury and its cause to sue. It also states that it revives claims that were already time-barred (NC General Assembly; WUNC). It should not be confused with HB 808 (2023), the state's ban on treating minors, which gives people treated as minors until 25 years after they turn 18 to bring a claim (UNC School of Government). Mosley moved to reinstate her claim under HB 805, but in August 2025 the trial judge declined to apply the revival and dismissed her case. Her appeal was argued in September 2026 and is undecided (Carolina Journal; see Prisha Mosley). Whether a legislature can revive claims already cut off by a statute of repose is the open legal question. Arkansas's 2023 Protecting Minors from Medical Malpractice Act created a 15-year window for claims over transition procedures done on minors (Arkansas Advocate).

The timing matters because detransition often comes years after treatment. In Littman's survey of 100 detransitioners, participants had been transitioned for an average of 3.9 years before detransitioning (Littman 2021). Among r/detrans stories analysed by detrans.ai with both dates recorded, the median gap between transition and detransition was 4 years, and about 11% detransitioned 10 or more years later (n = 997; self-selected sample, AI-extracted timelines) (detrans.ai stats). Recognising harm and finding a lawyer usually takes longer still. Ongoing cases are tracked on detransition lawsuits.

Who pays for detransition care

Texas (SB 1257, signed June 2025) requires health plans that cover transition procedures to cover complications and reversal care (Dallas Express). Montana's equivalent took effect on 1 October 2026 and protects people who were enrolled while transition coverage existed, even if the insurer later drops it (Montana Code 33-22-149). Tennessee advanced a similar bill in 2026, and a federal "TRUTH in Coverage Act" was introduced in Congress (The Federalist, partisan outlet). No equivalent laws were found outside the US. In a survey of 237 detransitioners, many reported unmet medical, psychological, social and legal needs (Vandenbussche 2022).

What detransitioners report

Detransitioners' accounts of the law centre on asymmetry: changing documents was easy, changing them back was not. One woman in Russia, where legal sex change is now banned, described being refused for a year:

it's been a year since I started the process of changing my documents back to female and they still refuse me. I don't know why. They think that detrans gender marker change is the same as trans?? also they say that detrans are worse than trans because we're dumb we changed it once and we want to change it back —thistle_ev, detrans female

In the US, some state offices still apply transition-era rules, such as proof of surgery, to people returning to their birth sex:

because they won't change my sex back to F without another surgical procedure. I've ranted about this before, because (Department of Motor Vehicles providing MEDICAL ADVICE aside) it's appalling to me that a person can be denied an accurately recorded sex based on the whims of some power-hungry dead-eyed "department" drone —trialeterror, detrans female

Even when the rules allow it, the process can be humiliating:

What did finally work was getting a supervisor and showing them my original birth certificate w/ my birth sex, then my first name-change order showing my identity change to a male name, then showing my current name change order to my new name. … Having to explain that out loud in front of an audience was beyond humiliating —L82Desist, detrans female

UK detransitioners describe the GRC as hard to undo, and some were relieved never to have applied:

Wanting to revert to your original birth certificate is not the same thing as seeking to change it in the first place and should not be treated as if it is. —DapperDhampir, detrans female

Some see sex-based document rules as a relief:

I'm mostly happy if this means that detransitioners who did change their sex on their docs can get it reversed back with little issues at least —kiwi33d, detrans female

It never should've been so easy to change gender markers in the first place —Shiro_L, detrans male

On lawsuits, deadlines are a recurring frustration:

I was outside the statute of limitations in my state, I detransitioned in 2021. —patrello, detrans female

On therapy, many commenters believe conversion therapy laws stop therapists from exploring alternatives. This is a perception of the laws' effect rather than a reading of their text, but it shapes who seeks help:

Identity, depression, and anxiety-focused therapy should be the starting place. The difficult kind that helps you get to know the hard questions you're maybe not asking yourself. The kind north american therapists aren't currently allowed to do since it's considered conversion therapy. —MightAfraid7338, desisted

Trans perspectives

Trans commenters describe the same laws very differently: as the loss of documents that kept them safe. Some non-binary people describe losing the "X" marker as a personal loss:

I identify as more masc nonbinary than cis male, so having the option for X felt so good for me when I was younger. It's so upsetting how much has changed since I was in high school. —Stray-Dragon-Rising, trans man (FTM)

Others worry about being recorded and tracked when they use legal workarounds:

The government has already said that any person applying with the attestation will be recorded into a database. —Nixphoe701, trans woman (MTF)

In the UK, trans commenters stress that the Supreme Court ruling concerned the Equality Act only and that a GRC still has effect for other purposes, a point also made by some detransitioners. Both groups share one practical complaint: legal systems that change rules quickly leave people holding documents that no longer match each other.

Limitations

• This is a survey of a fast-moving field, compiled from legislation, court documents, government pages and news reports up to October 2026. Several matters (Orr v. Trump, Kansas SB 244, Germany's evaluation, Slovakia's implementing rules, Turkey's draft, New Zealand's definitions bill) were unresolved, and some statuses may have changed since.
• Many countries, especially in Africa, the Middle East and parts of Asia, are not covered in detail.
• Some sources are advocacy organisations (TGEU, ILGA-Europe, HRW, ACLU, Egale, RFSL, Genspect, HRLA) or partisan outlets; they are labelled where cited, and factual claims were checked against primary or news sources where possible.
• Reversal rules are often found in regulations and registry practice rather than statute. Where "not confirmed" appears, readers should check with the relevant registry or a lawyer. This page is not legal advice.
• Detransitioner and trans accounts are drawn from Reddit and are self-selected; they illustrate experiences rather than measure how common they are.
