Legal Data Hunter

Open-source collection scripts for open legal data from 110+ countries.

Every country publishes its laws, court decisions, and regulations online -- but in different formats, behind different APIs, with different access rules. World Wide Law is building the open infrastructure to collect, normalize, and make all of it searchable.

All sources in this repository are open data -- publicly available legal information from official government portals, APIs, and bulk download endpoints. We always prefer API and bulk access over web extraction.

Live Dashboard & API

• Dashboard: legaldatahunter.com -- track coverage, explore sources, submit feedback
• Search API: Available at legaldatahunter.com -- search across 16M+ indexed legal documents

What's Here

This repository contains 960+ collection scripts across 110+ countries that download and normalize open legal data from government portals worldwide. Each script follows a standard interface so that any developer can run, test, or improve it. Some sources are marked as blocked (CAPTCHA, IP restrictions, etc.) -- their scripts are included so developers can review and potentially contribute fixes.

Quick Start

# Clone the repo
git clone https://github.com/worldwidelaw/legal-sources.git
cd legal-sources

# Install dependencies
pip install -r requirements.txt

# Check project status
python runner.py status

# Test a specific source
python runner.py sample FR/LegifranceCodes

# See what needs work
python runner.py next

How It Works

Per-Source Structure

Every source lives in sources/{COUNTRY_CODE}/{SourceName}/ and contains:

File	Purpose
bootstrap.py	Collection script -- implements fetch_all(), fetch_updates(), normalize()
config.yaml	Source metadata, access method, rate limits, schema
sample/	10+ sample documents for validation
README.md	Documentation about the data source
.env.template	Required API keys or credentials (if any)
retrieve.py	Reference resolver (e.g., "article 1240 code civil" -> document)

Two Data Models

Legislation (mutable): Laws get amended. Same ID, new content. Strategy: upsert with version tracking.

Case law (immutable): Court decisions don't change after publication. Strategy: append-only with dedup.

Standard Output Schema

Every script normalizes documents to a common schema:

• _id -- Unique identifier
• _source -- Source identifier (e.g., FR/LegifranceCodes)
• _type -- legislation or case_law
• title -- Document title
• text -- Full text content
• date -- Publication or decision date
• url -- Link to the original source

    rate_limiter.py        Token bucket rate limiter
    storage.py             JSONL storage with deduplication

Contributing

We welcome contributions from developers, legal researchers, and especially governments who want their open legal data included.

Who can contribute?

You are...	How you can help
Developer	Build or fix collection scripts, add retrieve scripts, improve tooling
Government official / jurisdiction lead	Tell us about your country's legal data portals — no coding needed
Lawyer / legal researcher	Validate data quality, improve legal reference resolution, flag coverage gaps
Anyone	Report data quality issues, broken sources, or coverage gaps

Submit a data source (no coding required):

• Open a "New Source" issue and tell us about your country's legal data portal

Fix or improve a collection script:

• See CONTRIBUTING.md for the full guide

Report a problem:

• Data quality issue -- missing or incorrect data
• Bug report -- broken script
