The Directorate General for Legal Certainty and Public Faith has confirmed that it is not possible to register a preventive seizure against a specific share (e.g. 50%) of a property registered under the community property regime. The land registry assessment establishes that any seizure must apply to the abstract share corresponding to the debtor in the asset, in accordance with Article 18 of the Mortgage Law and Articles 93 et seq. of the Mortgage Regulations.
For the Public Administration (the Social Security General Treasury), this ruling implies that seizure orders must align with the legal nature of the registered ownership. Merely proving the dissolution of the marital partnership due to death is insufficient to seize a specific physical or percentage part if the asset remains registered as community property. For individuals, it ratifies the protection of the abstract ownership share against enforcement actions on common assets.
