Medical Malpractice in Spain: How to Claim Compensation

🇪🇸 Read the original in Spanish

Undergoing medical treatment or surgery means placing our health, and sometimes our lives, in the hands of healthcare professionals. Although medicine is not an exact science and there are inherent risks to any procedure, patients have the right to receive care that meets the required quality and safety standards. When a healthcare professional acts with negligence, omission, or by departing from established protocols, we are faced with medical malpractice that can cause irreparable physical, moral, and financial damage. In this detailed guide, we explain how to identify malpractice, what legal avenues exist in Spain to claim, and how to obtain the compensation that legally belongs to you.

What is technically medical negligence? The concept of Lex Artis Ad Hoc

In the Spanish legal system, not every unsatisfactory or adverse result of medical treatment is automatically considered negligence. For the right to receive compensation to exist, a violation of the lex artis ad hoc (the standards of professional practice) must be proven. This indeterminate legal concept defines the evaluation criteria to determine whether the healthcare professional's actions conformed to the state of science and the good practices expected of a professional in their same specialty under the same circumstances.

The doctor's obligation, as a general rule, is an obligation of means and not of results. This means that the physician does not commit to curing the patient obligatorily, but rather to placing all available knowledge, techniques, and resources at their disposal to achieve it. However, there are exceptions in so-called "voluntary or satisfactive medicine" (such as cosmetic surgery, purely aesthetic dentistry, or vasectomy), where Supreme Court jurisprudence tends to bring the doctor's obligation closer to an obligation of result, making the requirement to meet the expectations promised to the patient more rigorous.

The legal framework in Spain: The Civil Code and the Civil Procedure Act

A claim for medical negligence is based on different legal texts of the Spanish legal system, depending on whether the damage occurred in private healthcare or public healthcare.

Contractual and non-contractual civil liability

When the negligence occurs in private healthcare (private clinics, medical insurance, or private consultations), the reference legal framework is found in the Código Civil (Civil Code):

• *Article 1902 of the Código Civil**: This is the pillar of non-contractual liability (responsabilidad extracontractual) in Spain. It establishes that "he who by action or omission causes damage to another, intervening fault or negligence, is obliged to repair the damage caused". For a claim under this article to succeed, three elements must concur: a negligent action or omission (breach of the lex artis*), economically assessable damage, and a direct causal relationship between the doctor's conduct and the damage suffered.
• *Article 1101 of the Código Civil**: This regulates contractual liability (responsabilidad contractual*). It applies when a direct contract exists between the patient and the clinic or doctor (frequent in cosmetic surgeries or dental treatments). It establishes that those who, in the fulfillment of their obligations, incur in fraud, negligence, or default are subject to compensation for the damages caused.

The procedural framework: The Civil Procedure Act (LEC)

To legally claim compensation in the civil jurisdiction, one must turn to the procedures regulated in Law 1/2000, of January 7, on Civil Procedure or the **Ley de Enjuiciamiento Civil (LEC)**.

• Expert evidence (Article 335 and following of the LEC): In medical negligence lawsuits, the key evidence is the report of expert witnesses. Article 335 of the LEC allows the parties to provide the process with reports from medical experts who possess the necessary scientific knowledge to assess whether a breach of the lex artis occurred. Without a solid expert report ratified in court, it is practically impossible to win a medical negligence lawsuit.
• Preliminary proceedings (Article 256 of the LEC): Before filing the lawsuit, the patient (future plaintiff) can legally request that the medical center or physician exhibit the complete medical history (historia clínica) if it has been denied or delivered incomplete.

Indispensable requirements for the right to compensation to exist

For a court or the public administration to uphold a medical liability claim, four concurrent requirements must be rigorously proven:

1. A faulty action or omission: The healthcare professional must have performed an act contrary to medical protocols (for example, a diagnostic error, leaving surgical material inside the body, or an incorrect prescription of medication).
2. The existence of real and assessable damage: The patient must have suffered a physical injury, a worsening of their health, moral damage, or a quantifiable financial loss. A mere "scare" or the possibility of having suffered damage is not compensable.
3. The causal link: There must be a direct and unequivocal cause-and-effect relationship between the negligence committed by the doctor and the final damage suffered by the patient. If the damage would have occurred anyway due to the patient's previous pathology, there will be no ground for compensation.
4. The lack of informed consent or defect therein: The patient has the right to know the risks of any intervention. If the doctor performs a procedure without the patient signing the consentimiento informado (informed consent), or if this document did not detail the specific risks that eventually materialized, there is negligence due to infringement of the patient's right to self-determination, which is susceptible to compensation even if the surgical technique was impeccable.

Claim avenues and legal deadlines: Watch the clock!

The deadline to claim for medical negligence is one of the most critical aspects, as it varies substantially depending on the type of healthcare center where the events occurred.

1. Administrative Avenue (Public Healthcare - SNS Hospitals)

If the negligence occurred in a public healthcare hospital or health center (managed by the Health Service of the respective Autonomous Community), a procedure for Patrimonial Liability of the Administration (Responsabilidad Patrimonial de la Administración) must be initiated.

• Statute of limitations: The deadline is 1 year (Article 67 of Law 39/2015).
• How is the deadline calculated?: The year begins to count from when the negligent event occurs or, in the event that sequelae (long-term effects) exist, from the moment of cure or determination of the definitive scope of the sequelae (when the patient's condition stabilizes and doctors determine that there will be no further improvement). In the event of death, the year is calculated from the date of demise.

2. Civil Avenue (Private Healthcare)

If the negligence occurred in a private hospital, private cosmetic clinic, dentist, or through private medical insurance.

• Statute of limitations: The general deadline to exercise personal actions that do not have a special deadline is 5 years (according to Article 1964 of the Código Civil for contractual relationships). However, for non-contractual liability (Article 1902 CC), the deadline is 1 year (Article 1968.2 of the Código Civil). To avoid risks of expiration, case law advises always acting under the 1-year deadline criterion from the stabilization of the sequelae, interrupting the deadline via burofax (certified registered mail) if necessary.

3. Criminal Avenue

Reserved for the most serious cases, where there is negligent homicide or injuries due to gross professional negligence (Articles 142 and 152 of the Código Penal [Criminal Code]).

• Statute of limitations: Varies between 1 and 5 years depending on the severity of the crime. This avenue is rarely recommended except in cases of extreme gravity, as criminal courts are very restrictive when it comes to convicting healthcare professionals.

Practical step-by-step steps to claim your compensation

If you suspect that you have been the victim of medical negligence, you must scrupulously follow these steps to guarantee the viability of your claim:

Step 1: Request your complete medical history

This is your fundamental right according to Law 41/2002 on patient autonomy. You must request in writing before the Patient Care (Atención al Paciente) service of the hospital or clinic a full copy of your file. This includes: evolution sheets, operating room reports, anesthesia sheets, signed informed consents, diagnostic test results (X-rays, blood tests, MRIs), and the nursing log.

Step 2: Gather complementary evidence

Keep all prescriptions, pharmacy receipts, invoices for private rehabilitation treatments, photographs of the state of the injuries over time, and receipts for transport expenses or home adaptation.

Step 3: Feasibility study by a medical expert

A lawyer specializing in medical negligence will refer your history to a specialist medical expert (perito médico) in the field of the negligence (for example, a gynecologist if the damage occurred during childbirth). The expert will analyze the case and issue a feasibility report determining whether a breach of the lex artis existed and if there is a causal link.

Step 4: Prior extrajudicial claim

Before going to court, it is common practice to send an extrajudicial claim (via burofax with acknowledgment of receipt and certification of text) to the civil liability insurance company of the doctor or health center, proposing an amicable agreement based on the damage assessment carried out by our expert.

Step 5: Lawsuit or administrative claim

If the amicable avenue fails:

• In public healthcare: The patrimonial liability claim is filed before the regional Health Service. If it is dismissed (or there is administrative silence after 6 months), you proceed to the Contentious-Administrative (Contencioso-Administrativo) courts.
• In private healthcare: A civil lawsuit is filed before the Courts of First Instance (Juzgados de Primera Instancia) demanding compensation for damages.

How is compensation calculated? Scales and real examples

To economically quantify the damage suffered due to medical negligence, Spanish courts apply by analogy the Scale for Traffic Accidents (Baremo de Accidentes de Tráfico - Law 35/2015, of September 22), which is updated annually. This scale divides the compensation into three major blocks:

1. Basic Personal Harm (Perjuicio Personal Básico): Compensation for the days of healing or stabilization (days off work).
2. Particular Personal Harm (Perjuicio Personal Particular): Compensation for permanent physical or psychological sequelae (measured in severity points), moral damage, loss of quality of life, and aesthetic harm.
3. Patrimonial Harm (Perjuicio Patrimonial): Includes consequential damage (daño emergente - future medical expenses, prostheses, home adaptation) and loss of earnings (lucro cesante - loss of financial income or future earning capacity of the patient due to the sequelae).

Example 1: Negligence in cosmetic surgery (Private Sector)

• Case: Lucía, aged 34, undergoes an breast augmentation mammoplasty in a private clinic for an amount of €6,000. Due to poor surgical technique and lack of asepsis, she suffers a serious infection that leads to tissue loss and severe asymmetry (significant aesthetic harm). She remains on medical leave for 90 days (of which 10 days require hospitalization) and is left with physical and psychological sequelae evaluated at 15 points of sequelae and 12 points of aesthetic harm.
• Approximate calculation of the compensation (according to the updated scale):
• For the healing days (10 days of very serious harm at €120/day + 80 days of moderate harm at €65/day): €6,400.
• For physical and psychological sequelae (15 sequelae points for a 34-year-old woman): €18,500.
• For aesthetic harm (12 points): €11,200.
• Moral damage for loss of quality of life: €10,000.
• Refund of the expenses of the negligent operation and future reconstructive surgeries: €12,000.
• Total Compensation: €58,100.

Example 2: Diagnostic delay resulting in death (Public Healthcare)

• Case: Carlos, aged 48, visits the emergency room of a public hospital on three occasions with severe chest pain. He is sent home diagnosed with "anxiety". On the fourth day, he dies of an acute myocardial infarction. He was married and had two children aged 12 and 16. The medical expert proves that a simple electrocardiogram on the first visit would have avoided the outcome (loss of therapeutic opportunity).
• Approximate calculation of the compensation for the family:
• Compensation for the widow (for basic personal harm and loss of the spouse's income): €140,000.
• Compensation for the 12-year-old child (personal harm and orphanhood): €90,000.
• Compensation for the 16-year-old child: €80,000.
• Total Compensation for the family: €310,000.

Mistakes you must avoid when claiming for medical negligence

Making a mistake during the early stages of the claim can completely ruin your chances of obtaining justice. Avoid the following:

• Letting time pass without interrupting the deadlines: The 1-year deadline flies by. If you are waiting for the hospital to respond to an internal complaint, the deadline to sue keeps running. You must send a formal burofax to interrupt the statute of limitations before the year expires.
• Claiming without a medical expert feasibility report: Filing a lawsuit based solely on your opinion or internet searches is a guarantee of absolute failure and being ordered to pay court costs (condena en costas), which will force you to pay thousands of euros of the opposing lawyers' fees.
• Accepting the first offer from the hospital's insurer: Insurance companies usually offer very low compensation quickly to prevent the patient from going to a specialist lawyer who will calculate the real damage according to the legal scale.
• Hiding medical history from the expert or your lawyer: If you had prior pathologies that influenced the final result of the operation and you do not mention them, the hospital's defense will use them in the trial to break the causal link and win the case.

Frequently Asked Questions (FAQ)

Can I claim if I signed the informed consent before the operation?

Yes, absolutely. Signing the informed consent means that you assume the typical and unavoidable risks of the intervention, but you never authorize the doctor to commit negligence or to act with a lack of care. Furthermore, if the consent was generic and did not specify the specific risk you suffered, you can claim compensation for lack of information.

What is "loss of opportunity" in medical negligence?

This is a legal concept (pérdida de oportunidad) applied when the medical error (usually a diagnostic delay or failure to perform a test) is not the direct cause of death or injury, but it did deprive the patient of the opportunity to be cured or to have a longer survival rate. The compensation in these cases is reduced proportionally according to the percentage of probability of cure that has been lost.

How much does it cost to initiate a lawsuit for medical negligence?

Initiating this process requires hiring a specialist lawyer, a court procurator or procurador (mandatory in most judicial processes), and a medical expert. Some law firms work on a "no win, no fee" (cuota litis) basis (charging a percentage of the compensation obtained, usually between 15% and 25%), but the costs of the medical expert (which usually range between €1,500 and €3,500 for the study and attendance at trial) are usually borne by the client.

Can I claim for negligence that occurred during childbirth if my child is already several years old?

Yes. The statute of limitations to claim damages suffered by a minor during childbirth does not begin to run until the minor reaches the age of majority or, in cases of severe sequelae such as infantile cerebral palsy, until the definitive scope and stabilization of the child's sequelae are determined, which is usually delayed several years during their development.

In summary

• Medical negligence requires proving that the healthcare professional breached the lex artis ad hoc (the required medical protocols).
• The general deadline to claim in public healthcare is 1 year from the death or stabilization of the sequelae, while in private healthcare it is advisable to act under the same 1-year deadline to avoid expiration.
• The complete medical history is the fundamental document that you have the right to request to initiate any legal action.
• The medical expert report is mandatory and constitutes the main evidence to prove malpractice and the causal link in court.
• Compensation is calculated using the Traffic Accident Scale as a guideline, evaluating physical, moral, aesthetic, and financial harm.
