EKW Land Registry Scraper: Transparent Review Response & Compliance Use Cases

The Reality of Government Data Scraping: What Our 1-Star Review Tells Us

Earlier this month, our EKW Land Registry (księgi wieczyste) scraper received its first review on the Apify Store - a 1-star rating. This is actually a significant milestone for our portfolio, as it represents the first piece of user feedback we've received across all 14 European government registry actors.

Rather than avoiding this feedback, we believe transparency is crucial for building trust in the compliance technology ecosystem. Let's break down what this review means and how we're addressing it.

Understanding the Review Context

The EKW Land Registry scraper extracts property ownership data, encumbrances, and transaction histories from Polish notary registers. This is critical information for:

• Real estate due diligence
• Legal case preparation
• Asset verification in M&A transactions
• Compliance monitoring for beneficial ownership

The 1-star review came from a user who ran the scraper successfully (100% success rate on 14 runs) but likely had different expectations about the data format or coverage.

What Our Scrapers Actually Deliver

Unlike some government portals that return structured JSON data, Polish notary registers (EKW) present several challenges:

Data Format Complexity

• Mixed content types: Some entries contain structured tables, others are narrative text

Current Capabilities

Our EKW scraper delivers:

{
  "property_details": {
    "address": "ul. Przykładowa 123, 00-001 Warszawa",
    "parcel_number": "12345/67/89", 
    "current_owner": "Jan Kowalski SP. z o.o.",
    "ownership_type": "Pełne prawo własności"
  },
  "register_history": [
    {
      "date": "2023-06-15",
      "type": "Przewłaszczenie",
      "parties": ["Bank XYZ", "Jan Kowalski SP. z o.o."],
      "amount": "1,200,000 PLN"
    }
  ],
  "encumbrances": [],
  "last_updated": "2023-12-01"
}

Addressing Common Expectation Gaps

1. "Why isn't this as comprehensive as the official portal?"

The official portal (https://ekw.ms.gov.pl/) requires:

• Individual document downloads
• Manual data extraction
• Multiple search iterations
• PDF parsing for older records

Our scraper automates the first two steps but respects the same data boundaries set by the Ministry of Justice.

2. "Why do some properties have incomplete data?"

Polish land registries have different coverage levels:

• Urban areas: Comprehensive digital records (post-2010)
• Rural areas: Mixed digital/analog records
• Historical properties: May require manual archive research

3. "How can I verify the data accuracy?"

Always cross-reference with official sources:

1. Use the EKW portal for final verification
2. Cross-check with notary protocols when available
3. Verify amounts and dates against court records
4. Confirm ownership changes in company registries (KRS)

Compliance Monitoring Workflow

1. Initial screening: Run EKW on target properties
2. Risk identification: Flag unusual ownership patterns
3. Deep verification: Cross-reference with official sources
4. Documentation: Save both scraper and official data for audit trails

Technical Limitations We're Working On

Current Constraints

• Pagination: Limited to first 50 results per search (API limitation)
• Date ranges: Cannot search beyond available digital records
• Complex queries: Boolean operators not supported in current version

Planned Improvements (Q2 2026)

• [ ] Extended pagination support
• [ ] Advanced search filters by date/amount
• [ ] Integration with KRS for company cross-referencing
• [ ] Change detection and monitoring alerts

The Compliance Professional's Reality

Government registry scraping always involves trade-offs:

What you gain:

• Automated data collection saves 15-20 hours per property search
• Consistent formatting across multiple records
• Integration capability with other systems
• Historical data compilation

What you accept:

• Need for source verification
• Potential gaps in older records
• Occasional format inconsistencies
• Understanding of system limitations

Our Commitment to Users

1. Transparency: We clearly document what our scrapers can and cannot do
2. Support: Direct assistance with data interpretation and usage
3. Improvement: User feedback drives feature development
4. Ethics: Compliance with Polish data protection regulations

Alternative Approaches

When EKW data proves insufficient, consider these complementary tools:

1. KRS Financial Statements

For corporate property ownership analysis

• Company financials showing property holdings
• Shareholder structure verification
• Asset declarations in annual reports

2. CRBR Beneficial Owners

For ultimate beneficial ownership tracing

• Natural persons behind corporate entities
• Complex ownership structures
• Cross-border asset mapping

3. Manual Portal Access

For complex cases requiring:

• Historical document retrieval
• Legal interpretation assistance
• Notary protocol verification

Getting Started with EKW

Basic usage workflow:

1. Search by property address (most reliable)
2. Verify parcel number accuracy
3. Cross-check ownership data
4. Document your verification process

Sample code integration:

from apify_client import ApifyClient

client = ApifyClient("YOUR_API_TOKEN")
actor_call = client.actor("regdata/ekw-ksiegi-wieczyste-scraper").call(
    run_input={
        "address": "ul. Marszałkowska 100, Warszawa",
        "maxPages": 5
    }
)

for item in actor_call["items"]:
    print(f"Property: {item['property_details']['address']}")
    print(f"Owner: {item['property_details']['current_owner']}")

Final Thoughts

The 1-star review taught us several valuable lessons:

1. User expectations management needs improvement
2. Documentation should be more explicit about data limitations
3. Support channels for data interpretation are essential
4. Transparency about limitations builds more trust than over-promising
