Source of funds asks where money used in a particular transaction came from. Source of wealth asks how a person's broader financial position was accumulated. The two questions can overlap, but they are not interchangeable. A balance snapshot might show that money exists without explaining either its immediate origin or its longer history.
Stake's published anti-money-laundering policy describes risk-based financial information, including source-of-funds and source-of-wealth requests. The 888casino UK agreement and Mr Green's general terms also describe additional financial checks. Read the relevant regional account terms rather than assuming one universal trigger or document threshold.
A transaction and a financial history
For an illustrative deposit funded from a salary payment, source-of-funds evidence might connect the salary receipt, the payment account and the deposit. The broader source-of-wealth question could concern income accumulated over time or other legitimate sources contributing to the person's overall financial position.
The specific evidence required depends on the request. A payslip can show an income event but may not show the transfer from one account to another. A bank statement can show a transfer but may not establish what generated the funds in the first place. Ask which link in the chain needs support.
These examples explain evidence categories; they are not advice on disguising activity or avoiding checks. Use accurate information and legitimate records. Do not fabricate a document, relabel transactions or create additional accounts to work around a request.
Ask for the scope before sending files
A useful request identifies the period, transaction or source under review, the categories of information required and the secure way to provide them. If a message says only prove your funds, ask for clarification so you can answer the actual question.
You can ask why a particular document category is relevant without assuming the organisation will reveal all of its internal risk assessment. The practical goal is to understand the evidence needed for a legitimate review and the process for supplying it.
If an account is awaiting that evidence before a withdrawal proceeds, record the request and response dates. The payment evidence guide helps separate a financial review from an already released payment that is delayed at a bank.
Follow the money without losing context
Consider a legitimate transfer between two accounts belonging to the same person. A statement showing the receiving account may show only an incoming transfer. If the operator needs the original source, a corresponding record from the sending account may be necessary to establish the link.
Now consider an asset sale. A sale agreement can explain why money was due, while a payment record can show when it was received. Neither document alone necessarily answers every part of a request. Keep the narrative short and factual: source, date, amount, receiving account and connection to the relevant transaction.
For crypto, a public transaction history can establish transfers between addresses but may not identify the account holder or the economic origin of the assets. A blockchain record is therefore not automatically a complete source-of-funds explanation. Crypto-network checks deal with routing; financial origin is a separate question.
Do not confuse wealth with affordability
A broad financial background and the money available for discretionary spending are different concepts. A person can own assets while lacking cash they can comfortably lose. A verification request should not be read as a suggestion to gamble at a higher amount because a document shows wealth.
Similarly, a completed financial review does not establish that gambling is harmless or suitable. The decision to spend must still respect essentials, commitments and personal limits. Money needed for rent, bills, food or debt payments should not become a gambling balance.
If reviewing your financial documents makes clear that gambling is affecting essential spending or causing stress, use support and account controls. You do not need to finish a promotion or recover losses before seeking help.
Keep the submission secure and limited to the request
Authenticate the channel through the operator's official account or published support service. Do not send financial files in reply to an unsolicited social message claiming to be a payment team. A genuine account enquiry should be traceable through the service you already use.
Ask how to handle unrelated transactions and sensitive fields. Follow verified instructions for acceptable redaction, and avoid obscuring information needed to assess the specific source. Redaction should protect privacy without changing the substance of the record.
Keep a private submission log with the file categories, dates and confirmation references. You usually do not need to circulate a full set of financial records among several informal contacts. A concise timeline can establish that requested material was supplied without exposing it publicly.
A checklist for understanding the request
| Question | What it clarifies |
|---|---|
| Is this source of funds, source of wealth, or both? | The type of evidence being requested |
| Which transaction or period is relevant? | The scope of the financial record |
| Which sources are being examined? | Salary, savings, sale proceeds or another legitimate source |
| Which links need documents? | Origin, transfer, ownership and receipt |
| What format and redaction are accepted? | How to provide readable evidence safely |
| What remains outstanding after submission? | The next actionable requirement |
The checklist does not determine whether a particular request is legally proportionate. That can depend on jurisdiction and circumstances. Its purpose is to make the operator's question and your response clear enough to discuss or review.
If the request expands or remains unclear
Record the original request, your response and the additional request. Ask what new category remains unresolved. There may be a legitimate difference between verifying ownership and verifying origin; repeated messages should identify that difference where possible.
If the account cannot obtain a clear explanation of what is missing, use the formal complaints procedure rather than repeatedly uploading unrelated records. Include the chronology and the specific unresolved issue. Our complaint guide explains how to organise that record.
Do not assume a review has completed simply because an upload tool accepted the file. Upload success, document acceptance and account clearance are separate events. Ask which event has occurred before using it to interpret a withdrawal status.
Answer the category that was actually asked
The most useful financial explanation connects the relevant source to the transaction and supplies the documents requested through a verified channel. A broader wealth question needs broader context; an identity document does not replace either task.
Keeping those categories separate reduces unnecessary disclosure and makes an account enquiry more precise. It also keeps verification from being confused with an endorsement of further gambling or a promise about the timing of a payment.
