What to expect
What you can find for free
- Registrations, officers and registered agents across states
- Public-company filings with the SEC
- Nonprofit tax returns (990s), including officer pay
- Trademark filings with owner names and addresses
- Federal lawsuits naming the business, and BBB complaints
Where free tools stop
LLCs can hide their owners behind a registered agent, and many states don't list members. Finding out who's really behind a company, plus its liens, judgments and reputation, is a due diligence report from a licensed investigator.
Tips
- Search the registered agent's address too. Shell companies often share one.
- For the most current filing, check the Secretary of State's site in the state where the company was formed.
