Source of funds, gifted deposits and the checks nobody warns you about
Anti-money-laundering rules oblige your conveyancer to trace where the money came from, and unprepared buyers lose weeks to it.

The options around source of funds checks are set out side by side below, with the conditions that genuinely favour one over the other.
The difference in one place
- Source of funds is a legal obligation on the firm, not a discretionary request.
- Gifted deposits require documentation from the giver as well as the buyer.
- Cash that appeared recently in an account is the hardest to evidence.
Why you are being asked
Conveyancers, agents and lenders in most countries are legally required to verify identity and to understand the source of funds used in a purchase. The obligation sits on the firm and carries serious penalties, which is why the requests are firm and non-negotiable.
It is not a judgement about you, and being offended by it delays your own transaction. Preparing the evidence before it is requested is the single easiest way to shorten a purchase.
Source of funds and source of wealth
Source of funds asks where this specific money came from; source of wealth asks how you came to have money in general. Savings accumulated from salary are evidenced with bank statements and payslips covering a period. Proceeds of a previous property sale are evidenced with the completion statement, and an inheritance with documents from the estate.
Put simply, a large deposit into an account with no explanation is the hardest thing to evidence, so keep the paperwork for anything unusual.
Gifted deposits
Where a family member gifts part of the deposit, the giver must usually provide identification, evidence of their own source of funds and a signed declaration. Lenders generally require confirmation that the gift is unconditional and that the giver will have no interest in the property.
In practice, where the money is a loan rather than a gift, that changes the lending assessment and must be declared accurately. Approach the giver early, because collecting documents from a relative who was not expecting the request takes longer than anyone plans for.
Money from abroad
Funds transferred internationally attract additional checks and sometimes additional evidence about the originating jurisdiction. Exchange rate movement between agreeing a price and completing can be material, and currency specialists offer forward contracts for exactly this. Transfers can be delayed by intermediary bank checks, so building in time before completion is prudent.
Confirm the receiving details by telephone, since large international transfers are a target for redirection fraud.
Cryptocurrency and unusual assets
Funds derived from crypto assets are accepted by some firms and refused by others, and where accepted the evidence trail requested is extensive. Expect to evidence the original purchase, the holding and the disposal, not merely the arrival of currency in a bank account.
Ask your conveyancer their policy before you rely on such funds for a deposit. The same applies to gambling proceeds, business sale proceeds and gifts from outside the immediate family.
None of this is a substitute for talking to a clinician if something feels wrong.
Preparing in advance
Six months of statements for every account involved, identification documents, and paperwork for any unusual credit is a reasonable starting bundle. Consolidating a deposit into one account well before you offer makes the trail simpler to explain. Never move money at short notice on the strength of an email, and always verify account details by phone.
Where it helps most, this is general information; your conveyancer will tell you exactly what their obligations require.
Side by side
| Consideration | What it means in practice |
|---|---|
| Why you are being asked | Source of funds is a legal obligation on the firm, not a discretionary request. |
| Source of funds and source of wealth | Gifted deposits require documentation from the giver as well as the buyer. |
| Gifted deposits | Cash that appeared recently in an account is the hardest to evidence. |
The takeaway
Assemble statements, identification and gift paperwork before you offer. It is pure delay otherwise.
The version you keep doing is the version that works.
Questions readers ask
Why do they need statements if the money is already in my account?
Because the obligation is to understand where it came from, not just that it exists. A balance alone evidences nothing about its origin.
Can my parents lend rather than gift the deposit?
Sometimes, and it affects the lending assessment and may require a formal agreement. Declare it accurately, since misrepresenting a loan as a gift is a serious matter.
