Learn Ownership & Sanctions

Business & Financial

Due diligence traces beneficial ownership — the real people behind shell companies — and screens names against sanctions lists (OFAC, EU, UN) and politically-exposed-person databases, consulting investigative leak databases like ICIJ Offshore Leaks. This is the backbone of KYC, AML, and anti-fraud work.

Knowing which company exists is not enough; you need to know who controls it. The beneficial owner is the natural person who ultimately owns or controls an entity, even when layers of shell companies obscure them.

Once you have names, you screen them. Sanctions lists from OFAC, the EU, and the UN identify parties you are legally barred from dealing with. PEP screening flags politically exposed persons — officials whose position raises corruption and bribery risk.

Investigative leak databases add another lens: the ICIJ Offshore Leaks database links individuals to offshore companies surfaced in major leaks. Together, beneficial-ownership tracing and screening form the backbone of KYC, AML, and anti-fraud due diligence.

Beneficial owner = the real controlling person.

Screen names against OFAC, EU, and UN lists.

PEP and ICIJ leaks add risk context.

# beneficial owner: who really controls
# sanctions lists: OFAC, EU, UN
# PEP screening: politically exposed

Read the implementation

Connect each part of the code to the concept before you type.

1. Real owner

The beneficial owner is the real person who ultimately controls a company, even behind shell entities.

# beneficial owner: who really controls

2. Sanctions screening

Names are checked against OFAC, EU, and UN sanctions lists to flag prohibited parties.

# sanctions lists: OFAC, EU, UN

3. PEP check

PEP screening flags politically exposed persons, who carry elevated corruption and bribery risk.

# PEP screening: politically exposed

4. Leak database

The ICIJ Offshore Leaks database links names to offshore entities revealed in investigative leaks.

# leaks: ICIJ Offshore Leaks database
