Proving the Source of Funds
Showing that money arrived from a particular account answers almost nothing at all. The question is where it was generated in the first place, and the distance between that point and the account it now sits in is where nearly all of the work turns out to be.
The rule in short
A source of funds inquiry asks how money came into existence rather than which account it last sat in. The answer requires evidence of the generating event, a documented path from there to the present holding, and consistency with everything else known about the person's finances. How far back the inquiry runs is set by the requirement rather than by preference.
Files answer this question by producing a statement showing the money in an account. That establishes possession. The inquiry is about generation: what event brought this money into the person's hands, and what happened to it since.
What the question actually asks
Where the money was generated. The event that created it: a sale, employment, a business distribution, an inheritance, a settlement or an investment return.
Not which account it came from. The immediately preceding account is a step in the path rather than an answer, and files routinely stop there.
Whether it is consistent with the person. Money substantially exceeding what somebody's known circumstances would generate prompts the question in the first place.
Whether the path is documented. The route from the generating event to the present holding needs records, which is the exercise in tracing a transfer.
Whether it is lawful. Some requirements ask specifically whether funds were lawfully obtained, which is a further question beyond origin.
How much of it is in issue. Requirements sometimes concern a specific sum and sometimes overall wealth, and the difference changes the scope entirely.
Evidencing the generating event
Sale of property. The contract, the completion statement and the receipt of proceeds into an identified account, together establishing both the event and the amount.
Employment income accumulated. Pay records and tax filings across the period, showing that savings of that size were possible, per pay records and what they show.
Business proceeds. Accounts, distribution records and the underlying business documentation, addressed in business income and its records.
Inheritance. The will or succession document, the estate accounts and evidence of the distribution reaching the person.
A gift. A declaration from the donor plus evidence of the donor's own source, because the question follows the money backwards through them.
Investment returns. Purchase records, holding statements and disposal documents establishing the gain and when it was realized.
Compensation or settlement. The award or agreement, together with the payment record showing the sum arriving.
| Origin | Primary document | Supporting |
|---|---|---|
| Property sale | Contract and completion statement | Receipt of proceeds |
| Employment savings | Pay records and tax filings | Statement history |
| Inheritance | Succession document | Estate distribution record |
| Business proceeds | Accounts and distributions | Corporate records |
| Gift | Donor declaration | Donor's own source |
How far back the inquiry runs
The requirement decides. Some ask only about the immediate origin of a specific sum, and others about the accumulation of wealth over many years.
Read it before gathering. The difference between those two scopes is enormous, and assembling for the wrong one wastes considerable effort.
Gifts extend the inquiry. Where money came from another person, that person's source frequently becomes relevant, and the chain lengthens accordingly.
Older events are harder. Records from decades ago may not exist, and the evidence available becomes secondary rather than primary.
Proportionality applies in practice. Modest sums attract less scrutiny than substantial ones, and the depth expected reflects the amount in issue.
Say where the account starts. A file that explains which period it covers, and why it starts there, is far easier to assess than one that simply begins somewhere.
Lawfulness is sometimes separate. Establishing where money came from does not always establish that it was lawfully obtained, and some requirements ask both questions.
Files answer this question with a statement showing the money in a bank. That establishes it was held, which nobody doubted. The answer required is the event that generated it, plus the documented path from that event to here.
What weakens a source of funds account
Money appearing without explanation. A large credit with nothing behind it is the entry that generates the inquiry and the one that has to be answered.
Inconsistency with declared income. Accumulated wealth substantially exceeding declared earnings requires an explanation that the file should already contain.
Cash deposits. Sums deposited in cash cannot be traced back beyond the deposit, which limits how far any account can go.
Circular transfers. Money moving between a person's own accounts and returning inflates apparent activity and is noticed.
Explanations without documents. A narrative describing where money came from, unsupported by records, is an assertion rather than an answer.
Recently assembled evidence. Documents obtained after the question was asked are acceptable, and documents created after it was asked are not.
Presenting the answer
Lead with the generating event. A reader wants to know first what created the money, and the path from there is detail supporting that answer.
Provide a chronological schedule. Dates, amounts and documents in order let a reader follow the accumulation rather than reconstruct it.
Attach the primary documents. Contracts, estate accounts and disposal records are what establish the origin, and statements alone do not.
Reconcile with tax filings. Where the origin was declared and taxed, the filing corroborates it, per tax returns offered as evidence.
Explain what cannot be documented. Older or informal parts of an account should be identified as such rather than presented at the same confidence as the rest.
Keep it proportionate to the sum. The depth of the answer should reflect the amount actually in question, and an exhaustive account of a modest figure invites questions of its own.
Answer the follow-up in advance. Where an origin will obviously prompt a further question, such as a gift from a relative, answering it in the same filing saves a round of correspondence.
A source of funds inquiry asks how money came into existence, and a file showing which account it arrived from has answered a different and easier question.
The generating event needs its own document: a sale contract, an estate account, a distribution record, a settlement agreement, or a run of pay records and filings showing that savings of that size were possible.
The path from that event to the present holding has to be documented as well, which is a tracing exercise, and it breaks in the usual places where cash or intermediaries were involved.
How far back the inquiry runs is set by the requirement rather than by preference, and reading it before gathering anything is what prevents an enormous amount of unnecessary or insufficient work.
Investment-based filings put source of funds at the center of the case, and the required depth is greater than in most other contexts. Where a filing turns on the origin and lawful accumulation of invested capital, an EB-5 investment attorney can say what the record has to establish.
Consistency is what makes an account credible. Where the origin reconciles with declared income and with everything else known about the person's finances, the answer stands; where it does not, the discrepancy is the case.
Points to carry away
- Source means where the money was generated, not where it was held.
- The generating event needs its own document.
- The path from origin to present holding must be documented.
- Consistency with declared income matters throughout.
- How far back to go is set by the requirement.
Questions readers ask
What is the difference between source of funds and source of wealth?
Source of funds usually concerns a particular sum: where this specific money came from and how it reached the account it is now in. Source of wealth is broader, asking how a person's overall financial position was built up over time. Requirements vary in which they ask about, and the scope of work differs enormously between them. Reading the requirement carefully before gathering documents is the single most useful step, because assembling material for the wrong one is expensive and does not answer the question.
How far back does an inquiry have to go?
As far as the requirement specifies, and proportionately to the sum in issue. Where money came from a property sale two years ago, the contract, completion statement and receipt of proceeds usually suffice. Where the sum is very large or came through a gift, the inquiry frequently follows the money further back, including into the donor's own source. Where records from the relevant period no longer exist, the honest approach is to identify that limit and explain it rather than to present an account with a silent gap.
Why is a bank statement not enough to show source of funds?
Because it shows possession rather than origin. A statement establishes that money was in an account on a date, and the question is what event brought that money into existence and how it traveled from there. The immediately preceding account is one step in a path, not an answer. What is needed is the primary document creating the money, such as a sale contract, an estate distribution or a run of earnings records, plus records of each movement between that point and the present.

Bank Statements and Their Gaps
Bank statements are persuasive because an institution produced them and because they are internally checkable. Their weakness is that they are supplied selectively. Missing pages, accounts that appear once and vanish, balances that do not carry forward and unexplained large movements are the features a reader notices before anything else in the file.
Undisclosed Assets, and How They Surface
Undisclosed assets are usually revealed by inconsistency rather than by searching. Transfers to accounts that appear nowhere else, spending that exceeds declared income, insurance and tax records filed for other purposes, and public registers all expose holdings. The consequences of non-disclosure are typically worse than the consequences of the asset itself.
Cash, and Why It Is Hard to Prove
Cash defeats the ordinary financial evidence because no third party records the transaction. What remains provable is that money was withdrawn, that a corresponding sum was deposited elsewhere, that circumstances changed consistently with the payment, and whatever contemporaneous notes or receipts the parties made. Building those into a coherent account is the only available route.
