Why Lawstronaut for Spanish legal research
Spanish legal information is spread across the state gazette, consolidated legislation, parliament, ministries, regulators, the courts, the Constitutional Court, and the legal frameworks of the autonomous communities. For humans, that means slow research. For AI systems, it's a bigger problem: fragmented source access, inconsistent formats, missing provenance, and weak citation trails.
Lawstronaut turns those sources into one structured legal data layer — source links, metadata, full text, versioning, and API/MCP access. Your product or agent retrieves the legal source directly instead of relying on generic web search or unverified model memory. Every answer carries a citation, a timestamp, and a link to the official document — the provenance that makes a legal research platform defensible to auditors and regulators.
About Spain legal coverage
Spain is a civil-law jurisdiction. State legislation is published in the Boletín Oficial del Estado (boe.es), which also maintains consolidated texts, while laws are debated and adopted by the Cortes Generales — the Congreso de los Diputados and the Senado. Case law is published through the Poder Judicial and the CENDOJ database, with constitutional rulings issued by the Tribunal Constitucional and leading decisions from the Tribunal Supremo. Regulatory guidance sits with bodies such as the Agencia Española de Protección de Datos and the Agencia Tributaria, with budgetary oversight by the Tribunal de Cuentas. Records are published in Spanish (Castilian), alongside co-official languages in several autonomous communities.
Spanish law moves quickly: the BOE publishes daily, reales decretos-leyes and reforms arrive on short timelines, EU-derived rules — the GDPR alongside the Ley Orgánica 3/2018 (LOPDGDD) — keep evolving, and the autonomous communities legislate in parallel across many fields. Point-in-time data straight from the source is what keeps a Spanish legal research answer correct today.
