Croatian law, in a form software can actually use
Statutes, consolidated law and court decisions are published across three separate portals, in formats built for reading rather than querying. ProIure ingests all three continuously and serves them as one searchable corpus, with the statutory date arithmetic that legal work actually turns on. It is the data layer under lawyer.ai.
The law is public. That is not the same as being usable.
Gazette statutes, consolidated laws and court decisions from three separate portals, served as one searchable corpus.
Running continuously, refreshed by scheduled ingest jobs. Available as a licensed API and as an MCP server.
The problem
Three portals, three formats, and none of them answer a question.
Croatian legal sources are public, which is not the same as usable. The official gazette publishes statutes as issues, not as law you can query. Consolidated texts live somewhere else again, and case law sits in a separate search portal. A lawyer checking whether a rule still applies, and what the courts have done with it, is reading three systems and reconciling them by hand.
- Statutes arrive as gazette issues, so "what does this article say today" is a reading exercise, not a lookup.
- Consolidated texts are convenient but unofficial, so authoritative work still has to go back to the gazette.
- Case law is searchable only one decision at a time, with no way to ask what cites what.
What it does
One corpus, kept current, with the maths that matters.
ProIure ingests all three sources on a schedule and normalises them into a single full-text-searchable corpus with document history, so you can ask what changed and when. On top of the corpus sit pure-compute tools: statutory deadline calculation under the Civil Procedure Act, which has to respect non-working days, and citation formatting and checking, which catches references to provisions that no longer exist.
- Over half a million legal documents in one place: gazette statutes, consolidated laws and court decisions.
- Full-text search across the whole corpus, plus document history and change comparison.
- Statutory deadline calculation that accounts for non-working days, rather than counting calendar days.
- Citation formatting and checking against the live corpus, so a dead reference is caught before filing.
- Watchlists on specific regulations, so a change to a rule you rely on surfaces on its own.
Why it exists
An assistant that cannot cite is worse than no assistant.
A general-purpose model asked about Croatian law will produce something confident and frequently wrong, because the law it needs was never reliably in its training data and it has no way to check itself. ProIure exists so the answer comes from the actual published text, with the source named. It is served as an MCP server as well as an API, so Claude and other assistants read the real corpus rather than recalling an approximation of it.
- 19 MCP tools: regulation lookup and history, court-decision search, and the legal compute tools.
- Every result carries its source, because the source portals require attribution on reuse.
- Authoritative text traces to the official gazette; consolidated texts are labelled as the convenience they are.

Sources
ProIure aggregates public Croatian legal sources and names them on every result, because their terms require it and because a legal answer without a source is not an answer.
- Narodne novine — the official gazette, and the authoritative text
- Zakon.hr — consolidated texts, a convenience and not authoritative
- odluke.sudovi.hr — the court-decisions portal
