Why Your Solicitor Needs Your ID
The ID and source-of-funds checks are a legal duty, not red tape. Here is what the rules require, why property is a target, and what to do if you cannot evidence something.
The Short Version
- Identity and source-of-funds checks are a legal requirement, not firm preference
- Property is a laundering target because it converts money into a stable asset
- Source of funds = where this money came from; source of wealth = your assets overall
- Gifts, inheritance and older savings often need extra evidence
- Each firm must do its own checks: it cannot rely on another's
- The rules apply UK-wide, in Scotland, England, Wales and Northern Ireland
The short answer
Solicitors and licensed conveyancers are legally required to verify your identity and the source of your money before acting for you. This is not bureaucracy for its own sake, and it is not the firm being difficult. It is a legal obligation under money-laundering regulations, and a firm that skipped it would be breaking the law and risking its ability to practise.
Why property is a target
Property transactions move large sums of money and convert it into a stable, valuable asset. That makes conveyancing an attractive route for laundering the proceeds of crime, which is why law firms handling property are designated as gatekeepers and held to strict checking duties. The checks protect the wider financial system, and they also protect you: robust identity verification is part of what guards against transaction fraud.
What "know your client" means in practice
The firm has to be satisfied of two things: that you are who you say you are, and that your money comes from a legitimate source. In practice that means:
- Identity: verified from a passport or driving licence, increasingly through an electronic ID check or an app that scans your document and matches it to a live photo of you
- Address: confirmed from a recent utility bill or bank statement
- Source of funds: evidence of where the money for the purchase came from
Source of funds versus source of wealth
These sound similar but differ. Source of funds is where the specific money for this purchase is coming from, the account it sits in and how it got there. Source of wealth is the bigger picture of how you accumulated your assets overall. Most straightforward purchases only engage source of funds, but larger or less usual transactions may prompt questions about source of wealth too.
Common sources and what tends to be asked for:
- Savings: statements showing the balance building up over time
- Sale of a property: the completion statement from that sale
- A gift: a signed letter, plus the giver's ID and evidence of their funds
- Inheritance: documentation from the estate or the executor
- A bonus or investment: payslips, dividend statements or sale contract notes
Why the checks sometimes feel heavy
If you have supplied ID many times before, being asked again can feel excessive. But each firm must carry out its own checks, it cannot simply rely on another firm having done them, and the rules have tightened over the years. A firm asking thorough questions is a firm doing its job properly, not one being obstructive.
What happens if you cannot evidence something
If a source of funds cannot be evidenced, the firm cannot proceed with that money. This is occasionally an issue with cash gifts, older undocumented savings or money held abroad. The solution is usually to build the paper trail (bank statements, transfer records, letters) rather than to abandon the transaction. Raising anything unusual with your solicitor early, honestly, is far better than it surfacing late.
Is it the same across the UK?
Yes. Anti-money-laundering obligations apply to solicitors and conveyancers throughout the UK, whether the property is in Scotland, England, Wales or Northern Ireland. The identity and source-of-funds requirements are essentially the same wherever you buy.
Common Questions
Frequently Asked Questions
Why does my solicitor need to check my ID?
Because money-laundering regulations legally require it. Solicitors handling property transactions are designated gatekeepers against the laundering of criminal proceeds, and must verify both your identity and the source of your funds before acting. A firm that skipped these checks would be breaking the law. The checks also help protect you against transaction fraud.
What is the difference between source of funds and source of wealth?
Source of funds is where the specific money for this purchase comes from, the account and how the money got there. Source of wealth is the broader picture of how you built up your assets overall. Most ordinary purchases only require source of funds; larger or less typical transactions may also prompt source-of-wealth questions.
Why do I have to prove my ID again when I have done it before?
Each firm must carry out its own checks and generally cannot rely on verification done by another firm. The rules have also tightened over time. Being asked again is not a sign the firm is being awkward; it is a sign it is meeting its legal obligations properly. Electronic ID checks have at least made the process quicker than it used to be.
What if I cannot evidence where my money came from?
If a source cannot be evidenced, the firm cannot use that money in the transaction. This sometimes affects cash gifts, older undocumented savings or funds held overseas. The usual answer is to build a paper trail with statements, transfer records and letters rather than to abandon the purchase. Flag anything unusual to your solicitor early and honestly.
