Compliance
SOW (Source of Wealth)
Source of Wealth
Definition
The compliance verification of how a player accumulated their overall wealth, applied to higher-risk customers especially in VIP relationships. Distinct from source of funds.
Why it matters
SOW verification is the broader compliance discipline complementary to SOF. While SOF establishes that specific gambling funds came from legitimate sources, SOW establishes that the player's overall wealth has legitimate origin: career income, business ownership and exits, inheritance, investment returns, asset accumulation. For VIP relationships with substantial gambling spend, SOW is essential to establish that the player's economic capacity supports the level of play observed.
The documentation requirements scale with complexity. A salaried professional with verifiable income provides relatively straightforward SOW evidence. A self-employed business owner, inheritor of family wealth, or beneficiary of asset sales requires more complex documentation: business accounts, asset valuations, wealth advisor confirmations, inheritance documentation. The friction is meaningful but the compliance defense for VIP relationships requires documented SOW. Operator-side specialist compliance teams handle VIP SOW work, often involving extended player relationships through the documentation process.
Frequently asked questions
Is SOW always required for VIP players?
Generally yes in regulated markets with mature AML expectations. UKGC and other major regulators have specific expectations around VIP customer due diligence including SOW verification. The threshold for SOW activation varies but VIP-level spending typically triggers the documentation requirement.
What evidence supports SOW?
Multiple sources: tax returns and tax assessments, business accounts and ownership documentation, asset valuations, inheritance documentation, investment portfolio statements. For complex profiles, professional opinions from accountants or wealth advisors may supplement direct documentation. The evidence base must be sufficient to satisfy the operator that overall wealth is legitimately sourced.
