Buying property in London requires assembling a specific set of documents before and during the transaction. The documentation falls into three categories: identity and anti-money laundering (AML) evidence required by your solicitor before the transaction can begin, financial documents demonstrating your ability to fund the purchase and the legitimate source of those funds, and the legal and property-specific documents your solicitor needs to complete the conveyancing process.
For international buyers, the documentation requirements are more extensive than for UK-based buyers — particularly around source of funds and identity verification. Assembling everything in advance, before an offer is made, eliminates the most common cause of transaction delay at the critical early stages.
Identity and Anti-Money Laundering Documents
UK solicitors are legally required to verify the identity of every client and the source of all funds used in a property transaction. This is a legal obligation under the Money Laundering, Terrorist Financing and Transfer of Funds Regulations 2017 — not a discretionary request.
Proof of identity (one of the following):
- Valid passport — the preferred and most straightforward document for all buyers, and the only universally accepted identity document for international buyers
- UK driving licence (photo card) — accepted for UK-resident buyers
- National identity card — accepted for EEA nationals
The identity document must be current and undamaged. Expired passports are not accepted even if the holder’s identity has not changed.
Proof of address (one of the following, dated within three months):
- Recent utility bill (gas, electricity, water, landline telephone) — mobile phone bills are not accepted by most solicitors
- Bank statement from a UK-regulated bank showing your name and current address
- Council tax statement dated within the relevant period
- Official government or HMRC correspondence
For international buyers who do not have UK address documentation, a bank statement from an overseas bank, a foreign utility bill, or official correspondence from a government authority in the country of residence is typically accepted — ask your solicitor what they require for your specific jurisdiction before sending documents.
Source of Funds Documentation
Source of funds documentation is the area that most commonly delays London property transactions, particularly for international buyers. Your solicitor must satisfy themselves not only that you have the funds to complete the purchase but that those funds are legitimately sourced.
For funds from employment income:
- Bank statements for 12 to 24 months showing accumulated savings from regular salary deposits
- If using a bonus payment: evidence that the bonus relates to your employment (employer letter confirming the bonus amount and reason)
For funds from a property sale:
- Completion statement from the sale of the previous property confirming the net proceeds
- Evidence that these proceeds have been deposited into the account from which the purchase funds will be drawn
For funds from business income or profits:
- Certified company accounts for the most recent two to three years
- Evidence of the dividend or profit distribution into personal accounts
- Accountant’s letter confirming the business relationship and the payment
For funds from inheritance:
- Grant of probate and evidence of the inheritance payment
- Estate accounts if available
For funds held in offshore accounts or international banks:
- Bank statements from the overseas account for 12 to 24 months
- These statements must typically be accompanied by a certified translation if not in English
- Your solicitor may require additional evidence of the original source of these funds
The most common delay in London property transactions is a buyer providing incomplete source of funds documentation after an offer is accepted, when time pressure is high. Providing complete documentation at the outset — before making an offer — eliminates this bottleneck.

Financial Documents for the Mortgage (If Applicable)
If purchasing with a mortgage, the lender requires its own documentation package alongside the solicitor’s AML requirements.
For UK-employed buyers:
- Three to six months’ payslips
- Current employment contract or employer reference letter
- Three months’ bank statements
- Most recent P60
For self-employed buyers:
- Two to three years’ certified accounts
- SA302 self-assessment tax return summaries
- Bank statements for three to six months
For non-resident buyers:
- Overseas equivalent of payslips and employment contract — with certified translations if not in English
- Overseas bank statements for three to six months
- Additional identity and residency documentation as required by the specialist lender
If purchasing in cash — without a mortgage — the lender documentation is not required, but the solicitor’s AML documentation must be more thorough, as there is no lender performing a parallel verification process.

The Legal and Property Documents
Your solicitor handles the legal documentation — this does not require you to assemble it yourself. However, understanding what your solicitor will receive and review helps you track progress and ask the right questions.
Documents received from the seller’s solicitor:
- Draft contract and title documents confirming the seller’s ownership and any encumbrances on the property
- Completed Property Information Form (TA6) — the seller’s disclosure of the property’s history, planning, disputes, and any known issues
- Fittings and Contents Form (TA10) — specifying what is included in the sale
- Leasehold Information Form (TA7) — for leasehold properties, confirming lease length, service charges, and ground rent
Documents your solicitor obtains:
- Local authority search — planning history, road proposals, enforcement notices
- Water and drainage search
- Environmental search
- Land Registry title register and title plan
Documents you sign:
- The contract of sale — signed by both buyer and seller at exchange
- Transfer deed (TR1 or TP1) — the legal document that transfers title into your name at completion
- Mortgage deed — if purchasing with a mortgage
- SDLT return — the stamp duty return filed by your solicitor within 14 days of completion
For International Buyers: Additional Considerations
Certified translations. Any document not in English — bank statements, employment contracts, identity documents from non-English-speaking jurisdictions — must be accompanied by a certified translation. Machine translations and informal translations are not accepted. Allow two to four working days for certified translation of any required document.
Power of Attorney. If you will not be in the UK for exchange and completion, a Power of Attorney must be prepared in advance, executed in your country of residence with appropriate notarisation and apostille, and provided to your UK solicitor. Prepare this well before it is needed — the notarisation and apostille process takes time and varies by jurisdiction.
SDLT non-resident surcharge. Non-UK residents pay an additional 2% SDLT surcharge. Your solicitor handles the calculation and filing — you do not prepare this document yourself, but you need to understand the calculation in advance so the correct funds are available at completion.

Conclusion
The documents needed to buy property in London divide into three categories: AML identity and source of funds documentation required by your solicitor; financial documents required by your mortgage lender if applicable; and the legal and property-specific documents your solicitor obtains and manages on your behalf. For international buyers, assembling identity, source of funds, and certified translation documents in advance — before any offer is made — eliminates the most common cause of early-stage transaction delays.
Frequently Asked Questions
Do I need to provide documents before making an offer on a London property?
You do not legally need to before making an offer — but assembling them in advance is strongly advisable. Providing complete AML and source of funds documentation to your solicitor before your offer is accepted means the legal process can begin immediately, avoiding the 1 to 3 week delay that typically occurs when buyers assemble documents reactively after an offer is agreed.
What source of funds documents does a London solicitor require?
Your solicitor requires evidence that the purchase funds are legitimately sourced — typically 12 to 24 months of bank statements showing the accumulation of funds, plus supporting documents for any specific source (sale completion statement for property sale proceeds, certified accounts for business funds, grant of probate for inherited funds). Overseas funds require the same evidence with certified translations where necessary.
Are there extra documents required for international buyers in London?
Yes — certified translations of any non-English documents, potentially a Power of Attorney if you will not be present in the UK for exchange and completion, and additional source of funds evidence for internationally held funds. The SDLT calculation will include the 2% non-resident surcharge, which your solicitor handles on your behalf.
