Company Registry Searches: Corporate Ownership Tracing

Most corporate investigations fail at the same step: someone finds a company name in a document, Googles it, pulls up a brochure, and stops. The actual ownership trail sits in registries. This tutorial covers the registries that matter, how to read their filings, and how to pivot across jurisdictions.

Due-diligence analysts, investigative journalists, compliance staff, and academic researchers mapping corporate structures.

What you'll need

  • Free accounts at OpenCorporates and OCCRP Aleph.
  • Browser access to the specific registries you plan to use.
  • A willingness to pay small fees for official filings — UK Companies House is free, but many state and national registries charge per document.

How it works

Every legally incorporated entity is registered somewhere. The registry holds at minimum the legal name, registration number, incorporation date, registered office, and officer list. Some jurisdictions (UK, EU members under the Anti-Money-Laundering directives) require a beneficial-ownership filing. Others (Delaware, most US states, and many offshore jurisdictions) do not. OSINT for corporate structures is largely the work of bridging jurisdictions that reveal ownership with those that do not.

Step-by-step walkthrough

  1. Start with OpenCorporates. Search the exact company name at https://opencorporates.com/. OpenCorporates aggregates over 200 jurisdictions and is often the fastest way to find out where a company is actually registered. Record the jurisdiction and the registry number.

  2. Go to the primary registry. OpenCorporates is a secondary source. For any finding you intend to publish, pull the same record from the primary registry:

    • UK: https://find-and-update.company-information.service.gov.uk/ (Companies House, free filings).
    • US federal securities: https://www.sec.gov/edgar/search/.
    • US state entities: the Secretary of State for the state of formation (Delaware, Nevada, Wyoming, and Texas are the most common for holding companies).
    • EU: https://e-justice.europa.eu/content_business_registers-104-en.do links each member state's registry.
    • Offshore: BVI, Cayman, Panama registries mostly require paid access and expose limited data.

  3. Extract the officer and filing history. On Companies House or SEC EDGAR, read every filing in chronological order. Changes in officers, registered office, or share structure are the ownership story. Exported CSVs of the filing list beat ad-hoc screenshots.

  4. Pivot on officers and addresses. Use OpenCorporates' officer search and the registry's officer links to find every other entity a director is attached to. Pay special attention to:

    • Mass-director addresses (a single flat listed on 400 companies indicates a nominee service).
    • Serial directors who appear across unrelated entities.
    • Dates of appointment and resignation clustered suspiciously.

  5. Check beneficial ownership where it exists. UK PSC filings, the EU beneficial-ownership registers (where still public), and FinCEN's BOI regime (for US entities, subject to evolving access rules) identify the natural person ultimately controlling an entity. Absent filings are themselves a signal.

  6. Bridge to sanctions and enforcement data. Search each identified natural person in:

    • OFAC SDN list (https://sanctions-search.ofac.treas.gov/).
    • UK HMT sanctions list.
    • OpenSanctions (https://www.opensanctions.org/).
    • Court records via PACER (US federal) or state court portals.

  7. Cross-reference with OCCRP Aleph. https://aleph.occrp.org/ indexes leaks (Panama Papers, Pandora Papers, many more) alongside public registry data. A matching record there often reveals the nominee-behind-the-nominee.

  8. Build the structure diagram. For each entity, record: name, jurisdiction, number, incorporation date, current officers, current registered address, latest filing date, beneficial owner (if known). Draw the ownership graph. Note the jurisdictions opaque enough that you cannot resolve a node.

Common pitfalls

  • Trusting brochures and press releases. The company's website and the company's filings often disagree. The filings win.
  • Ignoring "struck off" or "dissolved" status. A dissolved company can still be the layer through which assets moved historically. Pull its last filings.
  • Mistaking registered agent for owner. The registered agent on a Delaware filing is almost always a service provider, not the owner.
  • Confusing trading names with legal names. One legal entity often operates many brands; one brand often spans many entities.
  • Relying only on OpenCorporates. It is a wonderful starting point and a dangerous endpoint. Primary-registry citations are the standard for publication.

Verifying your findings

For any officer-to-entity or entity-to-entity claim, attach: the primary-registry URL, the filing ID, the retrieval timestamp, and a local PDF of the filing with a SHA-256 hash. Build the structure diagram from verified edges only. See the analysis phase guide for documenting complex entity graphs.
