Spain's Supreme Court has changed how inheritances are handled when an heir dies before accepting or rejecting a share. In judgment 849/2026, issued on 3 June 2026, the Civil Chamber abandoned the interpretation it adopted in 2013 and returned to the traditional “double transmission” approach, affecting the calculation of forced shares and heirs' rights.
The case centered on Article 1.006 of the Spanish Civil Code, which provides that when an heir dies without accepting or repudiating an inheritance, “the same right” passes to that heir's successors. The dispute is whether those successors inherit directly from the first deceased or through the estate of the intermediary heir. Under the Court's judgment of 11 September 2013, case reference 397/2011, the successors could inherit directly from the first deceased, bypassing the intermediary heir's estate. In practical terms, a grandchild could inherit from a grandmother without the relevant assets passing through the estate of the deceased parent.
The 2026 ruling restores the classic doctrine: when the intermediary heir dies without exercising the right to accept or reject the first inheritance, that right forms part of the intermediary's estate and passes to the intermediary's successors as universal heirs. The assets attributable to the intermediary in the first inheritance must so be counted in that estate before the succession is distributed to the next heirs. In its analysis of the judgment, Gómez-Acebo & Pombo described the result as successors inheriting from the first deceased “through the inheritance of the intermediary heir,” rather than through a direct transfer that skips the intermediary.
The practical effect of the change emerged in a family dispute. After a mother died, her son Justo passed away before accepting or rejecting her inheritance. Justo's widow, Eugenia, claimed rights connected to the mother's estate as Justo's surviving spouse and forced heir. The registrar initially denied her claim, relying on the 2013 doctrine, which would have excluded her from the inheritance. Under the Supreme Court's restored approach, the assets attributable to Justo in his mother's estate are included in his estate, supporting Eugenia's claim to a share. The ruling also affects who must participate in inheritance partitions and how estate inventories are drawn up.
The ruling reverses the Court's direct-transmission approach after approximately 13 years. The distinction reaches beyond which estate receives the assets: it can affect forced-share calculations and the surviving spouse's legal usufruct, while changing how estates are partitioned and creditors treated. Legal commentary on the judgment says the assets attributable to the intermediary in the first inheritance must be counted when calculating the spouse's legally protected share or usufruct. The change may so matter when pending succession matters involving Article 1.006 are reviewed, including registry applications and partitions.
Spain's inheritance law is based on the Civil Code, which sets rules on forced shares (legítimas) to protect certain heirs. Article 1.006 governs the transfer of an heir's unexercised right to accept or reject an inheritance when that heir dies. The Supreme Court's return to the double-transmission doctrine means the intermediary heir's estate is the legal channel for that right and the associated inheritance, with implications for family members and creditors, as well as for the administration and taxation of inherited assets. The ruling is also relevant to estate planning and the calculation of forced shares in Spain.
