Quick Overview:
As of July 1, 2025, it will no longer be necessary to undergo surgery or sterilization to legally change one’s gender. The Civil Code currently states that the date of gender change is the date specified in the confirmation issued by the healthcare provider. The Civil Registry Act provides for a subsequent entry of the gender change in the birth registry based on this confirmation. The healthcare provider must notify the civil registry office of the confirmation within three business days. However, the legal framework remains provisional, as the legislature has not yet adopted comprehensive new legislation.
The Basis of the Czech Legal System
The Czech legal system still recognizes only two genders—male and female—in official records. Gender is reflected in civil registry records, personal identification numbers, birth certificates, ID cards, travel documents, and other official data.
Czech law does not yet recognize a general official category for a third or non-binary gender. This does not mean that the state can ignore the dignity and privacy of people who do not identify with the gender recorded at birth. It does mean, however, that official changes are still processed within the male/female framework.
Until mid-2025, an official gender change was subject to a highly invasive requirement. The legal change was contingent upon surgical intervention involving the removal of reproductive function and the reassignment of genitalia. The Constitutional Court repealed this requirement in its ruling, case no. Pl. ÚS 52/23. It stated that the legal requirements for surgical transformation of the genitalia and the elimination of reproductive function are inconsistent with the right of transgender people to the protection of bodily integrity and personal autonomy in connection with human dignity.
At the same time, the Constitutional Court deferred the enforceability of the ruling until June 30, 2025, to give lawmakers time to adopt new legislation. However, a new comprehensive legal framework has not been adopted.Therefore, as of July 1, 2025, the legal framework will be based on legislation stripped of the unconstitutional requirement for surgery and on the methodology of the Ministry of Health.

Conditions and Procedure for Legal Gender Change
Section 29 of the Civil Code currently sets forth a concise rule: the date of gender change is deemed to be the date specified in the certificate issued by a healthcare provider. The provision no longer contains a clause making gender change contingent upon surgical intervention.
The Civil Registry Act further stipulates that a supplementary entry regarding the change of gender shall be made in the birth register based on a certificate issued by a healthcare provider. The provider must notify the civil registry office of this confirmation within three business days of the date of the gender change. The date of the gender change is the date specified in the confirmation.
The Ministry of Health’s methodological guideline, effective July 1, 2025, stipulates that the confirmation of fulfillment of the conditions for an official gender change is issued by the attending sexologist. The guidelines require confirmation of a diagnosis of transsexualism and the person’s informed consent. The treating sexologist must notify the civil registry office of the issuance of the confirmation within three business days of the date of the gender change.
In practice, therefore, the process typically involves:
- specialized care from a healthcare provider, typically a sexologist,
- a diagnostic process in accordance with current methodology,
- the individual’s informed consent,
- issuance of a certificate confirming fulfillment of the conditions for an official gender change,
- notification to the civil registry office,
- a subsequent entry of the gender change in the birth registry,
- subsequent replacement of identification documents.
As of July 1, 2025, surgical intervention, sterilization, or hormone therapy will no longer be a requirement for an official gender change. However, this does not mean that the official change will take place solely on the basis of a simple declaration to the civil registry office. Current practice still relies on confirmation from a healthcare provider.
Example: A person has been undergoing transition for a long time and is under the care of a sexologist. After the diagnostic criteria are met and an informed consent form is signed, the sexologist issues a confirmation stating the date of the gender change. This confirmation is submitted to the relevant civil registry office, and the change is made in the civil registry based on it.
A Gender-Neutral Name Before the Change Is Finalized
The law also provides for situations where a person is undergoing gender transition but the official change has not yet been completed. Under the Civil Registry Act, a natural person who has begun treatment for a gender change may declare to any civil registry office that they will use a neutral first name—or names—and last name. An attachment to this declaration is a confirmation from a healthcare provider that treatment for gender transition has begun.
Gender-neutral names can be helpful to some individuals. A person who already lives in accordance with their gender identity can use them to avoid unpleasant everyday situations when dealing with government agencies, banks, schools, employers, or doctors. However, some people say that using a gender-neutral name can, on the contrary, draw attention.
After completing gender-affirming treatment, a person may declare that they will use a different first name—or names—and last name. If they do not do so and have not previously used a gender-neutral name, the civil registry office will enter the last name in the birth register in a form corresponding to the new gender; it will not enter the first name in the birth register and will notify the court.
In practice, therefore, it is advisable to address the issue of the name in a timely manner. This is not merely an aesthetic or personal matter. The name is recorded in identification documents, contracts, employment records, school systems, bank accounts, and other public and private records.
Official Changes: Birth Certificate, Social Security Number, and Documents
An official gender change is followed by updates to the civil registry and other records. The basis for this is an additional entry in the birth register. Based on this entry, a new birth certificate with updated information can be issued.
A gender change is usually reflected in the birth number as well. The Czech personal identification number system still uses different formats based on gender; therefore, after a gender change, a new format for the personal identification number must also be arranged. Subsequently, the ID card, passport, driver’s license, and other documents are updated.
In practice, we recommend proceeding in the following order:
- verify the gender change entry in the civil registry,
- apply for a new birth certificate,
- obtain a new birth number,
- apply for a new ID card,
- then replace your passport, driver’s license, and other documents,
- notify your employer, school, bank, insurance company, health insurance provider, and other institutions of the change.
Although many changes are automatically updated across public systems, you cannot rely on this in all private-sector relationships. A bank, employer, school, or insurance company may require a new ID card or a new birth certificate.
Example: After a gender transition and the issuance of a new ID card, it may be necessary to update your employment contract, payroll information, access systems, bank accounts, insurance policies, and health insurance records. Changing the documents themselves is therefore not the final step, but rather the beginning of the process of administratively updating the information.
Legal Consequences of a Gender Change
A gender change takes legal effect as of the date specified in the confirmation issued by the healthcare provider. This date is important for the civil registry, identification documents, the birth number, and other legal consequences.
The Civil Code also stipulates that a gender change does not affect a person’s marital status or their personal and financial circumstances; however, it explicitly states that a marriage or registered partnership is dissolved.
This provision is a sensitive issue in practice. It is neither a divorce nor a judicial dissolution of the union. The dissolution occurs directly by operation of law. If two people wish to remain in a legally recognized union even after one of them changes their gender, they must subsequently determine what status Czech law allows them—marriage, a partnership under the Civil Code, or another legal framework for their relationship. Since 2025, Czech law has recognized a partnership as a permanent union between two people of the same sex, which is entered into in the same manner as marriage.
The dissolution of a marriage due to a gender transition may primarily affect:
- the spouses’ joint property,
- housing,
- estate planning,
- spousal support between former spouses,
- custody of joint children,
- tax and social security matters,
- contracts in which the other person is referred to as a husband or wife.
The Civil Code states that the provisions governing divorced spouses apply mutatis mutandis to the rights and obligations of a man and a woman whose marriage has been dissolved due to a change of gender with respect to their child, as well as to their property rights and obligations following the dissolution of the marriage. The court will decide, even without a motion, how each parent will care for the child going forward.
For individuals living in a domestic partnership or a registered partnership, we recommend legally reviewing the specific implications before undergoing a gender transition. The legal framework governing partnerships has changed significantly since 2025, and in practice, it may be decisive whether the partnership is an older registered partnership, a new partnership under the Civil Code, or a foreign union.
Gender Transition and Relationships with Children
A parent’s gender transition does not, in and of itself, revoke parental rights or obligations. The parent remains the child’s parent, retains the obligation to provide child support, parental responsibility, the right to information, and the duty to act in the child’s best interests.
At the same time, a gender change does not automatically rewrite the legal history of parenthood. If a person was listed as the father or mother on the child’s birth certificate, the gender transition alone does not mean that they retroactively become the “second mother” or “second father” in the sense that the original parental title would be automatically rewritten. It is always necessary to distinguish between a parent’s personal identity and the legal determination of parenthood.
Practical issues may arise, however. The child may need time, explanation, and support. The other parent may have concerns or may use the change as an argument in a custody dispute. However, a court cannot restrict parental rights simply because a parent has undergone or is undergoing a transition. The child’s best interests, the quality of care, safety, stability, and the parents’ ability to cooperate are always the deciding factors.
Example: After legally changing their gender,a parent continues to pick up the child from school, pays child support, communicates with doctors, and provides the child with a stable home environment. A gender transition in and of itself is not grounds for the other parent to restrict the child’s contact with that parent or to demand a significant restriction on custody. The situation would be different only if there were specific circumstances endangering the child—but the court would assess those circumstances in the same way as it would for any other parent.

The Significance of the Constitutional Court’s Ruling
The Constitutional Court’s ruling, Case No. Pl. ÚS 52/23, is groundbreaking because it removed one of the most stringent conditions for official gender reassignment under Czech law. The Constitutional Court repealed the first sentence of Section 29(1) of the Civil Code and the first sentence of Section 21(1) of the Act on Specific Health Services, effective as of June 30, 2025.
The Court emphasized that the previous legislation forced transgender people to face an unacceptable choice: either undergo an invasive and irreversible procedure or remain listed in official records in a manner inconsistent with their deeply held identity. It characterized such an interference as disproportionate and contrary to human dignity.
However, the Constitutional Court did not say that the state is prohibited from regulating the conditions for gender reassignment at all. It acknowledged that the state may have a legitimate interest in legal certainty, the stability of status data, and the prevention of frivolous changes. The legislature therefore has the discretion to establish new rules, but it must respect bodily integrity, personal autonomy, and human dignity.
This is precisely where the current problem lies. Surgery can no longer be a requirement, but the legal procedure is still very brief. As a result, current practice relies on a combination of the Civil Code, the Civil Registry Act, and the Ministry of Health’s guidelines.
Future Outlook for Legal Regulation
As of June 2026, the legal framework for gender reassignment remains incomplete. The Civil Code contains only a brief sentence regarding the date of gender reassignment, and the Civil Registry Act relies on confirmation from a healthcare provider. The Ministry of Health’s methodological guidelines standardize the medical procedure but do not have the force of law.
In the future, it will be necessary to clarify, in particular:
- who issues the confirmation and under what conditions,
- whether a gender change will be a purely medical, administrative, or judicial process,
- how minors will be handled,
- what the conditions will be for any subsequent changes,
- how the relationship to the personal identification number will be regulated,
- how the changes will affect marriage, civil partnerships, and parenthood,
- how to ensure consistent practices among civil registry offices and other authorities.
For people who are currently going through a gender transition, it is therefore important not to rely solely on general information found online. It is advisable to verify the procedure in advance with your attending physician, the relevant civil registry office, and—in cases involving family or property implications—a lawyer as well.
Summary
As of July 1, 2025, an official gender change in the Czech Republic will no longer be conditional on surgical intervention or sterilization. The Constitutional Court repealed this requirement, ruling it an unconstitutional infringement on bodily integrity, personal autonomy, and human dignity.
However, the current law is not fully developed. The Civil Code stipulates that the date of gender change is the date specified in the confirmation issued by the healthcare provider. The registry office makes an additional entry in the birth register based on this confirmation. The practice is based on a methodological guideline from the Ministry of Health, according to which the certificate is issued by the attending sexologist following a diagnostic process and informed consent.
A gender change has practical implications for the birth certificate, social security number, identification documents, first name, last name, marriage, registered partnership, property relations, and parenthood. However, parental rights and obligations do not automatically cease with a gender change.
Frequently Asked Questions
Will surgery be required for a legal gender change starting in 2025?
No. As of July 1, 2025, neither surgery nor sterilization is a requirement for a legal change of gender. The Constitutional Court struck down the legal provision that required surgery.
What are the current requirements for a legal gender change?
The basis for this is a certificate issued by a healthcare provider. The Civil Code stipulates that the date of gender reassignment is the date specified in this certificate.
Who issues the confirmation?
According to the Ministry of Health’s methodological guidelines, the attending sexologist issues a certificate confirming that the conditions for a legal gender change have been met, provided that diagnostic procedures confirm the diagnosis and the person signs an informed consent form.
Do I have to change my name first?
You don’t always have to. However, the law allows a person who has begun gender reassignment treatment to declare to any civil registry office that they will use a gender-neutral first and last name. After completing treatment, they may declare that they will use a different first and last name.
What happens to a marriage after a gender transition?
The Civil Code stipulates that a change of gender does not affect a person’s personal or property status, but a marriage or registered partnership is dissolved. With regard to rights and obligations concerning a child in common and property relations, the rules applicable to divorced spouses apply mutatis mutandis.
