Lovdata

Name: Lovdata
License: NLOD

Search all current Norwegian acts and central regulations via Lovdata's official API (opened in Nov 2025, NLOD 2.0). Open bulk packages (current acts + central regulations, kept up to date with amendments) are freely available without a key; granular full-text search and structured single documents require a free X-API-Key. The foundation for legal analysis, legislation search and RAG/AI services (#1124).

Ready-made tools built on Lovdata data. Use them directly in the browser, or wire the same data into your own analysis via the API below.

Lovdata

Look up current Norwegian acts and regulations: date code, ministry, legal area and entry into force, together with the latest announcements in Norsk Lovtidend and the legislative cases before Stortinget. For full text of the law itself, use Lovsøker.

Legal-document lookup

Look up current Norwegian acts and central regulations by legal citation (LOV/FOR) or title — with dates, legal area and a link to full text via Lovdata's open catalogue.

Legislation catalogue

Bulk catalogue of all current Norwegian acts, central regulations and Norsk Lovtidend — straight from Lovdata's open-data API (NLOD 2.0). Download XML packages with lastModified for incremental delta detection.

Legislation search

The primary search surface for legislation: browse and filter Lovdata's open catalogue of current acts, central regulations and Norsk Lovtidend, and search the law text itself (full text). To download the entire catalogue as XML, use Lovkatalog.
