Source of Wealth (SOW) requirement – what is it?
What is a Source of Wealth (SOW) requirement? — a question that bank clients and investors often face when withdrawing large sums or opening accounts. Source of Wealth (SOW) translates as "source of state". Unlike source of funds (SOF), which confirms the origin of specific funds, SOW describes the general origin of the client's capital

What is Source of Wealth (SOW)?
- Definition Source of Wealth is a documented proof of the origin of the client's wealth as a whole.
- Difference from SOF. SOF confirms an individual transfer, while SOW covers the entire capital.
- Regulatory grounds. AMLD5 and AMLD6 require financial institutions in the EU and UK to carry out such checks.
- For those who need it. SOW is most often requested by wealthy clients when making investments and opening corporate accounts.

When is a SOW request legal?
- when opening a bank account with large turnovers;
- when investing in real estate, business or the stock market;
- for transfers over €100,000;
- if the client belongs to the PEP (politically exposed person) category.
What documents confirm the Source of Wealth?
- tax returns for recent years;
- income certificates, employment contracts;
- corporate reporting;
- documents on the sale of a business or shares;
- documents of inheritance or gift;
- court decisions (for example, division of property);
- investment reports and dividend payments.
When do scammers use SOW?
- a broker or pseudo-bank requires payment for a “SOW check”;

- After submitting documents, new fees appear (“AML fee”, “unlock fee”).
