Advance Wishes Document Spain (Documento de Voluntades Anticipadas)

An Advance Wishes Document Spain (Documento de Voluntades Anticipadas), also known as Instrucciones Previas or Testamento Vital, is a formal legal document through which a competent adult records their wishes regarding medical treatment, healthcare decisions, and organ donation to take effect in the event they lose the capacity to make or communicate those decisions, governed principally by 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), Article 11, which establishes the right of every person with legal capacity to issue prior instructions for medical treatment.

Article 11.1 of Ley 41/2002 defines the Instrucciones Previas as instructions through which a person expresses in advance their will regarding medical interventions they may receive, values and life instructions the author wishes respected, and the designation of a substitute decision-maker (representante) to interpret and apply those wishes if the author cannot do so directly. The document is also commonly called Voluntades Anticipadas across Spain's autonomous communities, with each community having adopted its own implementing legislation — for example, Ley 5/2003 de Castilla-La Mancha, Ley 3/2005 de la Comunidad de Madrid, Ley 1/2003 de la Comunitat Valenciana, Ley 5/2015 del País Vasco (Ley de Derechos y Declaración de Voluntad Anticipada), and Ley 5/2010 de Andalucía.

The document operates across three principal domains: (1) medical treatment directives — instructions regarding the acceptance or refusal of specific medical interventions, including the right to refuse extraordinary life-prolonging treatment (encarnizamiento terapéutico), resuscitation, artificial nutrition, or palliative sedation; (2) organ donation preferences — whether the author consents to or refuses organ and tissue donation after death under Ley 30/1979 sobre extracción y trasplante de órganos and Real Decreto 1723/2012; and (3) appointment of a healthcare representative (representante) — a trusted person authorised to interpret and implement the author's wishes.

The Documento de Voluntades Anticipadas must be executed with full capacity (plena capacidad) and is not valid if the author lacks legal capacity at the time of execution. Formal requirements vary by autonomous community: some require execution before a notary (notario) under the general rules of the Ley del Notariado (Ley de 28 de mayo de 1862); others accept execution before three adult witnesses (testigos) who are not relatives or close associates; and others allow registration at the autonomous community's registry (Registro de Voluntades Anticipadas or Registro de Instrucciones Previas) without notarial intervention. The national Registro Nacional de Instrucciones Previas (RNIP), created by Real Decreto 124/2007, de 2 de febrero, integrates all community registries and makes the document accessible to healthcare professionals throughout Spain.

Registration with the RNIP — accessed through the health system's electronic records (Historia Clínica Digital) — confirms that the document is available to attending physicians, hospitals, and emergency services across Spain regardless of where the medical situation arises. The Ministerio de Sanidad coordinates the RNIP. Once registered, the document takes precedence over any oral or undocumented preferences attributed to the author. Physicians are legally required to respect the registered Instrucciones Previas under Article 11.3 LAP unless the instructions are contrary to the legal order, good clinical practice, or are circumstances not foreseen by the author.

The Documento de Voluntades Anticipadas can be modified, renewed, or revoked by the author at any time while they retain capacity, pursuant to Article 11.4 LAP. Revocation must also be communicated to the RNIP. The document complements but does not replace other legal instruments such as the Poder Notarial para Asuntos de Salud (healthcare power of attorney) and the appointment of a tutor (guardian) under the Código Civil Articles 215 et seq. as reformed by Ley 8/2021, de 2 de junio, de reforma de la legislación civil y procesal para el apoyo a las personas con discapacidad en el ejercicio de su capacidad jurídica.

An Advance Wishes Document Spain is needed whenever an adult in Spain wishes to confirm that their preferences about medical treatment are respected in the event of illness, accident, or incapacity — the document gives legal force to personal healthcare values before a crisis makes direct communication impossible.

A Documento de Voluntades Anticipadas is required when a person has been diagnosed with a serious or progressive illness — such as cancer, dementia (Alzheimer's disease, Lewy body dementia), Parkinson's disease, or amyotrophic lateral sclerosis (esclerosis lateral amiotrófica — ELA) — and wishes to record in advance their preferences regarding palliative care, pain management, resuscitation (reanimación cardiopulmonar — RCP), and mechanical ventilation before the disease progresses to a stage where those decisions can no longer be communicated directly.

The document is needed when a person has strong personal, religious, or ethical objections to specific medical treatments — such as blood transfusions (relevant for Jehovah's Witnesses), organ donation, or post-mortem examination — and wishes those objections to be legally documented and binding on the healthcare team.

A Voluntades Anticipadas is necessary when a person wishes to appoint a healthcare representative (representante designado) — a trusted family member, friend, or legal advisor — to make healthcare decisions on their behalf if they become incapacitated. Without a formal appointment, family members have no automatic legal authority to override medical decisions, and conflicts between family members and healthcare providers are resolved by the ethics committee (comité de ética asistencial) of the relevant hospital under Ley 41/2002.

The document is also appropriate for healthy adults of any age who wish to document their end-of-life preferences — including the right to receive adequate palliative care and sedation under Ley Orgánica 3/2021, de 24 de marzo, de regulación de la eutanasia (LORE), which introduced regulated euthanasia in Spain. The Voluntades Anticipadas can express the author's position on medically assisted dying, which is relevant to the assessment of the patient's sustained wish required by LORE Articles 5 and 6.

The Documento de Voluntades Anticipadas is required before planned surgery or high-risk medical procedures in Spain — patients undergoing major operations who wish to document their preferences in case of complications causing incapacity should register the document with the RNIP in advance and provide a copy to the hospital's clinical documentation service.

A valid Advance Wishes Document Spain under Ley 41/2002 Article 11 must contain the following essential elements to be registered with the Registro Nacional de Instrucciones Previas (RNIP) and to be legally binding on healthcare providers.

Identification of the Author: Full name, DNI or NIE, date of birth, and address of the person issuing the instructions. The author must be an adult (18 years or older) with full legal capacity (plena capacidad de obrar) at the time of execution. Where a person has limited legal capacity under Ley 8/2021 de apoyo a personas con discapacidad, a judicial authorisation may be required.

Statement of Capacity: An express declaration by the author that they are executing the document with full awareness and in the free exercise of their right to health self-determination under Article 11 LAP and Article 15 of the Constitución Española 1978 (right to physical integrity).

Medical Treatment Directives: Specific instructions regarding: (1) acceptance or refusal of extraordinary life-prolonging treatment (obstinación terapéutica); (2) resuscitation instructions (cardiopulmonary resuscitation — RCP); (3) mechanical ventilation and artificial nutrition; (4) palliative sedation and pain management; (5) hospitalisation or home care preference; and (6) any treatment refused on religious or personal grounds. Instructions must be limited to lawful treatments — Article 11.3 LAP expressly excludes instructions that are contrary to the legal order (e.g. requesting euthanasia in a community that has not implemented LORE) or good clinical practice.

Organ Donation Preference: A clear statement of consent to or refusal of organ and tissue donation after death under Ley 30/1979 sobre extracción y trasplante de órganos and Real Decreto 1723/2012, de 28 de diciembre, by which Spain regulates transplant activities. Spain operates an opt-out system (consentimiento presunto) under Article 9 Real Decreto 1723/2012 — all persons are presumed donors unless they have expressly objected. The Voluntades Anticipadas is the primary mechanism for recording this objection or, conversely, for reinforcing consent and limiting donation to specific organs.

Designation of Healthcare Representative (Representante): The full name, DNI, address, and contact details of the person designated to interpret and apply the author's wishes. The representative must accept the appointment in writing. The document should clarify the scope of the representative's authority — whether they may consent to or refuse treatments not explicitly addressed in the document, and how they should resolve conflicts with family members or healthcare professionals.

Values Statement (Declaración de Valores): An optional but strongly recommended section in which the author explains the personal, philosophical, or religious values underlying their instructions — providing context for the healthcare representative and treating physicians when faced with unforeseen medical situations not expressly covered by the specific instructions.

Formal Execution Requirements: Depending on the autonomous community, execution requires: (a) notarial deed (escritura pública) before a Notario de España; (b) execution before three adult witnesses (testigos mayores de edad) with capacity, who are not related to the author by blood or marriage up to the second degree, and who will not inherit from the author; or (c) execution before a designated civil servant of the autonomous community health authority. The specific requirements of the relevant Comunidad Autónoma must be verified — for example, in Catalonia the document is governed by Llei 21/2000 (Ley 21/2000 del Parlament de Catalunya) and requires specific Catalan registry registration.

Registration Clause: Reference to registration with the Registro de Voluntades Anticipadas of the relevant autonomous community and the national Registro Nacional de Instrucciones Previas (RNIP) under Real Decreto 124/2007. Registration is not constitutive of validity — the document is valid from execution — but registration confirms accessibility across the Spanish health system.

Forms-legal.com provides this Advance Wishes Document Spain template as a starting point — the formal requirements vary significantly by autonomous community. Consultation with a notary (notario), a healthcare law specialist (abogado especialista en derecho sanitario), or the autonomous community's health authority is strongly recommended before execution and registration with the RNIP and the Consejo Nacional de Especialidades en Ciencias de la Salud. The Ministerio de Sanidad's official RNIP portal (msn.gob.es) provides autonomous community-specific guidance.

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.
