Spanish Supreme Court recognises the partner's own moral damages after a failed vasectomy without risk disclosure: 35,000 euros each

The Third Chamber (Fifth Section) of the Spanish Supreme Court has delivered judgment 1174/2026 of 21 October, recognising with unprecedented clarity the spouse or partner's own moral damages where a patient underwent a failed vasectomy without being informed of the risk of spontaneous recanalisation. The Chamber upholds the appeal, quashes the Madrid High Court's ruling and sets compensation at 35,000 euros for each of the two appellants, plus statutory interest.

Informed consent: strictly personal ownership, extensible consequences

The central doctrinal piece of the judgment is a fine distinction. The right to healthcare information and to informed consent belongs exclusively to the patient: it is a strictly personal right tied to their autonomy and to their fundamental right to physical and moral integrity. Nobody can consent on their behalf or demand to be informed in their place. But the fact that the right is strictly personal does not mean its harmful effects are exhausted in its holder.

When the lack of information about the risks of the procedure frustrates the life project of both members of the couple, in this case their shared decision not to have more children, the breach of the duty to inform can generate an autonomous, compensable moral damage in the partner as well. It is the application to the healthcare sphere of the category of reflected or derived moral damage, with which Spanish case law already worked in other contexts.

The case: a vasectomy, an unwanted pregnancy and an undisclosed risk

The couple turned to the courts after a vasectomy which, although technically performed correctly, ended in spontaneous recanalisation and pregnancy. The couple did not claim over the outcome itself but over not having been informed that such an outcome was possible: had they known the risk, they argued, they would have adopted complementary contraceptive measures. The Madrid High Court rejected the wife's claim, considering that the duty to inform bound only towards the patient. The Supreme Court now corrects that point: exclusive ownership of the right does not exclude compensation for the own damage suffered by third parties intimately linked to the affected life project.

The amount, 35,000 euros per person, is justified by the intensity of the moral damage suffered by both during the unplanned pregnancy and its consequences. It is not an automatic tariff: the judgment anchors it in the circumstances of the case, leaving room for quantitative defence in future files.

A doctrine with partial precedents

Reflected moral damage is not an invention of this judgment: Spanish case law had been admitting it in scenarios such as the death or serious injury of a relative. The novelty is its clear transfer to the healthcare field and, specifically, to the lack of informed consent. The Chamber stresses that the partner is not compensated for being a partner, but because the omitted duty also protected, in truth, their shared life project. That reasoning matters because it delimits the perimeter: not everyone affected by malpractice will have a right of their own, only those who prove an intimate link with the frustrated life project and actual moral damage.

Practical keys for law firms

Three notes for practice. First, the judgment does not relax informed consent but strengthens it: the safest route for clinics and insurers remains documenting specifically the risks communicated, including the risk of technique failure. Second, in the claim it is advisable to individualise the patient's moral damage and the partner's as separate concepts, each with its own evidentiary basis. Third, the route is judicial review of administrative action where the service is public, as here, but the doctrine on derived damage is transferable to civil jurisdiction for private healthcare.

The judgment fits within a line of controlled expansion of reflected moral damages that we have been following in our news section. For designing intake and consent processes in the firm, we recommend our matter-opening checklist and the analysis of lawyers' liability and ethics.
