Advance Directives Spain (Instrucciones Previas / Voluntades Anticipadas)

Advance Directives Spain (Instrucciones Previas or Voluntades Anticipadas) is a formal written document in which an adult person with full legal capacity (capacidad de obrar plena) — while in full mental capacity — expresses their wishes regarding the medical treatment, healthcare interventions, and personal care they would want (or refuse) if they become unable to make or communicate decisions in the future, and designates a healthcare representative (representante sanitario) to act on their behalf before the healthcare team, governed by Article 11 of Ley 41/2002, de 14 de noviembre, básica reguladora de la autonomía del paciente y de derechos y obligaciones en materia de información y documentación clínica (LAP).

Ley 41/2002 (LAP) is the national framework statute for patient rights in Spain, establishing the principle of autonomía del paciente — the patient's fundamental right to make informed decisions about their own healthcare — as the cornerstone of the Spanish healthcare relationship. Article 11 LAP specifically regulates instrucciones previas, providing that any adult person with capacity may execute them to govern future medical treatment when incapacity supervenes. The document is binding on all healthcare professionals and healthcare centres (centros sanitarios) — both public (Sistema Nacional de Salud) and private — that attend the patient throughout Spain.

The constitucional foundation for advance directives rests in Article 15 of the Constitución Española 1978 (right to life and physical and moral integrity) and Article 18 CE (right to personal privacy and dignity — intimidad personal). The Tribunal Constitucional has affirmed in STC 120/1990 and STC 11/1991 that the right to refuse medical treatment — even life-sustaining treatment — is a component of fundamental rights, subject to the state's competing interest in protecting life. Ley Orgánica 3/2021, de 24 de marzo, de regulación de la eutanasia (LORE) adds an additional dimension to advance directives in Spain — the document can now include a request for euthanasia (prestación de ayuda para morir) under the conditions established by Articles 3–6 LORE, making Spain one of a small number of EU Member States to permit advance directive requests for euthanasia.

All Autonomous Communities in Spain have enacted their own instrucciones previas legislation, which supplements and develops the framework of Article 11 LAP. The Autonomous Community registries (registros autonómicos) — such as the Registro de Voluntades Anticipadas de Cataluña, the Registro de Instrucciones Previas de la Comunidad de Madrid, and the Registro de Voluntades Vitales Anticipadas de Andalucía — allow residents to register their document and confirm it is accessible to healthcare professionals. Since 2021, all Autonomous Community registries are interconnected with the Registro Nacional de Instrucciones Previas (RNIP), managed by the Ministerio de Sanidad under Real Decreto 124/2007 — a document registered in any Autonomous Community registry is accessible to healthcare professionals anywhere in Spain through the RNIP.

Article 11.2 LAP establishes three exclusions — instrucciones previas may not request treatments that are contrary to the legal system (e.g. homicide), contrary to la lex artis médica (clinical best practice), or outside the clinical offering of the healthcare centre. The 2021 LORE amendment removed the prohibition on requests for euthanasia where euthanasia is now legal, subject to the conditions of LORE Articles 3–6 (the person must be suffering from a serious incurable or chronic debilitating disease, and the desire for euthanasia must be serious, informed, and reiterated).

Advance Directives Spain (Instrucciones Previas) should be executed by any adult Spanish resident who wishes to confirm their healthcare preferences are respected if they become unable to communicate due to accident, progressive illness, dementia, or other causes of incapacity — while they still have full legal capacity to execute the document.

The document is particularly relevant for persons diagnosed with progressive neurological conditions — Alzheimer's disease, Parkinson's disease, multiple sclerosis, ALS — where cognitive incapacity is anticipated. Neurologists, psychiatrists, and geriatricians at Spanish hospital Servicios de Neurología and hospital units of the Sistema Nacional de Salud routinely recommend that patients execute instrucciones previas shortly after diagnosis, while capacity is unquestionable.

Instrucciones previas are needed for persons who wish to refuse specific life-sustaining treatments in terminal situations — mechanical ventilation (ventilación mecánica), cardiopulmonary resuscitation (reanimación cardiopulmonar — RCP), artificial nutrition and hydration (nutrición e hidratación artificiales), or haemodialysis — that they would not want applied if there is no reasonable prospect of recovery. Without an instrucciones previas document, Spanish healthcare professionals are legally obligated to apply all available life-sustaining measures unless the patient actively refuses in the moment — the documento replaces that immediate consent in situations of incapacity.

The document is required when a person wishes to designate a specific representante sanitario to speak to doctors on their behalf — the designated representative has decision-making authority that family members (familiares) — including spouses — do not automatically possess under Spanish healthcare law. Without a designated representante, healthcare decisions in incapacity situations are made by the attending physician (médico responsable) in consultation with the family, but no single family member has a binding veto.

Instrucciones previas should be executed by Spanish residents of all ages who have strong personal, religious, or ethical views about end-of-life care — whether those views favour all possible interventions or the withholding of specific treatments. The document is also the vehicle through which a person may express wishes regarding body donation (donación de cuerpo a ciencia), organ donation (donación de órganos — regulated separately by Real Decreto 1723/2012), and the destination of any biological samples after death.

The document must be executed before incapacity occurs — once a person lacks capacity, the instrucciones previas can no longer be validly executed or amended. Spanish notaries (Notarios) registered with the Colegio Notarial and Autonomous Community registrars confirm capacity at the time of execution.

Under the Código Civil Articles 657–1087, Spanish succession law applies the legítima system (forced heirship). The Ley del Notariado governs testamentary forms (abierto, cerrado, ológrafo). The Impuesto sobre Sucesiones y Donaciones (ISD) Ley 29/1987 taxes inheritances. Foral regions (País Vasco, Navarra, Cataluña, Aragón, Baleares, Galicia) have distinct succession rules. The Reglamento UE 650/2012 governs cross-border EU successions.

Valid Advance Directives Spain under Article 11 of Ley 41/2002 (LAP) and Autonomous Community implementing regulations must contain the following key elements to be legally binding on healthcare professionals and registerable in the RNIP.

Declarant Identification: Full name, DNI or NIE, date of birth, address, and telephone or email of the declarant (otorgante). A capacity statement — declaring that the person is executing the document with full legal capacity (plena capacidad de obrar) and in a state of freedom from coercion — is essential for validity. Witnesses, a notario, or an administrative official (funcionario competente) must attest to capacity at the time of execution, depending on the Autonomous Community's formal requirements.

Healthcare Representative (Representante Sanitario): The name, DNI, contact details, and relationship to the declarant of the designated representante sanitario — the person authorised to communicate with the healthcare team, access the clinical history (historia clínica), and make healthcare decisions on the declarant's behalf when capacity is absent. A substitute representative should also be named in case the primary representative is unable or unwilling to act. The representative's acceptance (aceptación expresa) should be documented — some Autonomous Community registries require the representative to sign the document or a separate acceptance form.

General Healthcare Values Statement: The declarant's fundamental values (valores vitales) — religious or philosophical convictions about life, death, dignity, and suffering — that should guide the interpretation of all specific instructions. This values history (historia de valores) is the foundation of the document — it contextualises specific instructions and enables the representante and healthcare team to apply the declarant's wishes to unforeseen clinical situations.

Specific Treatment Instructions — Positive: Treatments the declarant affirmatively requests — palliative care (cuidados paliativos) including adequate pain management and sedation; artificial hydration and nutrition in specified circumstances; specific diagnostic measures.

Specific Treatment Instructions — Negative (Rechazo de Tratamientos): Treatments the declarant refuses in specified clinical circumstances — typically: mechanical ventilation (ventilación mecánica) when irreversible; cardiopulmonary resuscitation (RCP) when there is no reasonable prospect of neurologically intact survival; artificial nutrition and hydration (ANH) in terminal phase; renal dialysis (diálisis) in terminal phase. Each refusal must specify the clinical circumstances in which it applies — open-ended refusals without clinical context are difficult for healthcare professionals to apply and may lead to conflicting interpretations.

Euthanasia Request (Optional — Post-LORE 2021): If the declarant wishes to include a request for euthanasia (prestación de ayuda para morir) under Ley Orgánica 3/2021 (LORE), the document must comply with LORE Articles 3(c) and 6 — the declarant must have been diagnosed with a serious incurable disease or a chronic debilitating condition causing intolerable physical or psychological suffering, and must express a serious, informed, reiterated, and persistent desire for euthanasia. Euthanasia requests in instrucciones previas are subject to the Comisión de Garantía y Evaluación established in each Autonomous Community under LORE Article 17 before they can be acted upon.

Organ and Body Donation: The declarant's position on organ donation (donación de órganos post-mortem) — Spain's opt-out presumed consent system under Ley 30/1979 and Real Decreto 1723/2012 applies unless documented refusal — and body donation for medical teaching or research (donación de cuerpo a ciencia médica), governed by Real Decreto 1090/2015 and managed by the anatomy departments of public universities.

Revocation Clause: A statement that the document may be revoked or modified at any time while the declarant has capacity, in accordance with Article 11.4 LAP, by executing a new document, by express written revocation, or by registration of the revocation in the RNIP or Autonomous Community registry.

Forms-legal.com provides this Advance Directives Spain template as a practical guide. Every person executing instrucciones previas should consult their Autonomous Community registry for specific formal requirements — some communities require witnesses (testigos) who are not relatives, while others accept execution before a Notario or before a competent administrative official. The document should be registered in the RNIP or Autonomous Community registry immediately after execution to confirm healthcare professionals can access it through the Sistema Nacional de Salud's electronic health record (historia clínica digital) at any time.
