Spain's Gender Change Registry Guide

Changing one's registered gender in Spain is a free procedure based on self-determination, requiring no medical reports or treatments.

## The Legal Path to Changing Your Registered Gender

Since Law 4/2023, known as the "Trans Law," came into force, the process for modifying the sens entry in the Spanish Civil Registry has changed radically. Medical diagnoses, psychological reports, hormone treatments, and surgeries are no longer required. Published in the Official State Gazette (BOE) on February 28, 2023, this regulation replaces the previous Law 3/2007, which imposed much stricter requirements. The key principle is gender self-determination, allowing anyone over 16 to request rectification of their registered sens based solely on their own will. The Instruction of May 26, 2023, by the Directorate-General for Legal Security and Public Faith details how this is applied in practice at Civil Registries.

Article 44 of Law 4/2023 is explicit: the change of registered sens "shall in no case be conditioned upon the prior submission of a medical or psychological report regarding the discrepancy with the sens mentioned in the birth registration, nor upon the prior modification of the applicant's appearance or bodily function through medical, surgical, or other procedures." This means no medical certificate, witnesses, or justification beyond your own declaration can be requested. The law focuses on the individual's will and eliminates the health barriers that previously existed.

## Who Can Apply and How Does the Process Work?

The law contemplates different scenarios depending on the applicant's age. Individuals **over 16** can initiate the process completely autonomously, without needing accompaniment or consent from others. For youths between **14 and 15**, assistance from legal representatives is required; if they disagree, a judicial guardian will be appointed. Minors between **12 and 13** need prior judicial authorization, processed as a voluntary jurisdiction file, before going to the Civil Registry. Those under 12 are excluded from this specific procedure, though they may request a name change. Support measures for people with disabilities are also included.

The procedure itself consists of two appearances. The first takes place at the Civil Registry, where the application is submitted stating disagreement with the registered sens. At this stage, a new name can be chosen if desired, provided it meets general rules (not denigrating, not misleading about sens, etc.). After this first appointment, there is a mandatory waiting period of up to **three months**, considered a reflection time. The second appearance is to ratify the decision. If you do not attend to ratify, the file expires and you must start over. The resolution is issued in writing within a maximum of one month from ratification, and the change is registered. In practice, the entire process usually lasts between **four and five months**.

## Costs and Subsequent Steps

The rectification of the sens entry in the registry is **free**. There are no fees associated with the application or registration. Basic documentation typically requested includes a valid ID card/NIE or passport, and in some cases, a recent residence certificate to prove the competent Civil Registry. Although many Civil Registries do not require an appointment to start the file, it is advisable to confirm this detail with the specific office, as management may vary.

Once the change is registered in the Civil Registry, it is essential to update all official documentation. This involves requesting an updated birth certificate, which will serve as the basis for renewing the ID card and passport, health card, Social Security information, tax agency data, and driver's license, among others. Links to book appointments with these bodies are usually available on their respective electronic portals, such as **citapreviadnie.es**, **importass.seg-social.es**, or **sede.agenciatributaria.gob.es**.

## Reversibility and Important Nuances

A relevant antiestéticature of the law is the **reversibility** of the change. If a person decides to reverse the rectification, they can request to return to the previous sens entry trinc the same procedure, but only after **six months** have passed since the registration of the change. For any subsequent changes after this first reversal, the law requires judicial authorization, aiming to prevent abusive use of the procedure.

It is important to note that Article 46.3 of the law establishes that the change of registered sens "shall not alter the legal regime applicable to the person prior to the registration of said change." This has practical implications, for example, in the application of Organic Law 1/2004 on gender violence. If a person is being investigated or prosecuted for acts occurring before the change of registered sens, this does not exempt them from the application of the law for those already completed acts. According to various legal commentators, this remains an area with some interpretive uncertainty for future cases. For foreign residents in Spain, the Ministry of Interior has approved a specific police protocol to process sens changes in their immigration documents, separate from the Civil Registry.
