Registering as an organ donor is a meaningful decision that can save lives. This guide explains how to register as an organ donor in Spain.
You will find information on Spain’s donor registry, the opt-out consent system, and donor card applications. Standard steps and legal rules are compared below.
Spain’s opt-out organ donation system
Spain operates an opt-out consent system for organ donation. Under this model, all residents are considered potential donors after death.
The Spanish term for this opt-out system is consentimiento presunto (presumed consent).
However, in practice, medical teams always consult the deceased person’s family before proceeding. They will not go ahead if the family objects.
The Spanish term for family is familia (family). For this reason, it is important to communicate your decision clearly to your relatives.
The state department managing transplants is the Organización Nacional de Trasplantes (National Transplant Organization).

The Spanish donor card
You can obtain a donor card to state your wishes clearly and assist your family.
The Spanish term for the donor card is tarjeta de donante (donor card).
The card is a personal document that states your wish to donate organs after death. It is free and requires no medical tests.
The card is not a legal contract. It acts as a clear statement of intent for your family and doctors.
The registry of advance directives
You can register your donation wishes in the official registry of advance directives for absolute legal certainty.
The Spanish term for advance directives is instrucciones previas (advance directives).
The document is stored in the regional healthcare registry. The Spanish term for this registry is registro de instrucciones previas (registry of advance directives).
You can also submit this document at the civil registry. The Spanish term for the civil registry is Registro Civil (Civil Registry).
A registered living will is legally binding. It overrides any objections raised by family members after your death.
Opt-in versus opt-out donation systems
Spain’s system differs significantly from the opt-in systems used in many other countries.
In an opt-in system, you must actively register to be considered a donor. If you do not register, you are assumed to not want to donate.
In Spain’s opt-out system, consent is presumed. This model has helped Spain become a world leader in organ donation rates.
This table compares the two donation systems.
| Feature | Opt-in system | Opt-out system (Spain) |
|---|---|---|
| Default status | Non-donor | Potential donor |
| Action required | Must register to donate | Must register to object |
| Family consultation | Family usually decides | Family consulted but registry overrides |
| Donation rates | Typically lower | Typically higher |
