What Documents Do Overseas Buyers Need to Purchase UK Property?

You’ll be asked for four things: proof of who you are, proof of where you live, proof of where the money came from, and if you’re buying through a company, proof of what that company is and who controls it. Everything else is a variation on those four.

Nobody is being suspicious of you personally. UK solicitors, estate agents, sourcers and lenders are all supervised under the Money Laundering Regulations, and they can’t complete a transaction without this file being complete. The delays happen when a document arrives late, in the wrong format, or in a language nobody has had translated.

Get the pack together before you find a property, not after. Deals move on days, and a certified passport copy takes longer to obtain from abroad than most people expect.

1. Proof of identity

Document	What is accepted	Notes
Passport	Current, unexpired, photo page	The default. A national ID card is often accepted alongside it, rarely instead of it.
Driving licence	Photocard, current address	Usually treated as secondary, not primary
Second photo ID	Residence permit, national ID card	Some firms ask for two forms if you aren’t physically present

If you can’t attend an office in person, the firm is required to apply extra checks precisely because you’re remote. That’s normal and it isn’t a judgement on you. In practice it means a certified copy rather than a scan, and sometimes a live video verification call.

2. Proof of address

One document, in your name, showing your residential address. A PO box or a company address won’t do.

Utility bill (electricity, gas, water, landline)
Bank or credit card statement
Council tax or its local equivalent
Government correspondence, for example a tax notice

Dated within the last three months. That three month rule is convention rather than statute: the regulations don’t publish a document list, so each firm sets its own policy and almost all of them land on three months. Assume three, and if your bill cycle is quarterly, ask for the most recent one now rather than in six weeks.

If your address documents are in a language other than English, you’ll need a translation. Some firms want it certified by the translator, some will accept a plain one. Ask before you pay for it.

3. Source of funds, and source of wealth

This is where transactions actually stall. “Source of funds” means where this specific money came from. “Source of wealth” means how you came to have money at all. You may be asked for both, and they’re answered with different documents.

What satisfies it:

Salary or bonus: six months of payslips plus the matching bank statements showing the credits landing
Business income or dividends: company accounts, dividend vouchers, and a statement from your accountant
Sale of a property: the completion statement from the sale, plus the bank statement showing the proceeds arriving
Sale of a business or shares: the sale agreement or contract note, plus the receiving statement
Inheritance: the grant of probate or its local equivalent, plus a solicitor’s letter confirming the distribution
Gift: a signed letter from the person giving it, their ID and proof of address, and evidence of where their money came from. A gift doesn’t remove the question, it moves it one person along.
Savings accumulated over time: the hardest one to evidence. Bank statements going back far enough to show the balance building, not a single statement showing a large balance appearing.

Two practical rules. Show the money’s whole journey: statements need to connect, so if funds moved between three accounts, supply all three. And expect a query on any single credit you can’t explain, however small it looks next to the purchase price.

Money coming from a jurisdiction on the UK’s high risk list will attract additional checks. So will being, or being related to, a politically exposed person, meaning a senior public official, minister, head of state or their immediate family. Neither of these blocks a purchase. Both add time, so declare them early rather than letting the firm discover them.

4. If you are buying through a company

Buying in a corporate name adds a whole second file, because the firm has to identify the company and then identify the humans behind it.

Certificate of incorporation
Memorandum and articles of association
Register of shareholders and directors
Proof of the registered office address
ID and proof of address for every director, and for every beneficial owner holding more than 25 percent
A structure chart if there are holding companies in between, going up to the ultimate individual owners

If the company is registered outside the UK, it must also be on the Register of Overseas Entities before it can be registered as the owner of UK land. This is not optional and there is no way around it. The registration fee is £250, the entity must give details of its beneficial owners, and the checks must be carried out by a UK regulated agent within the three months before you register. You receive an Overseas Entity ID which the Land Registry requires. Registration then has to be updated annually, within 14 days of the anniversary. An unregistered overseas entity cannot properly complete a purchase, so start this early. Details are on GOV.UK (checked 25 August 2026).

Whether a company is the right structure at all is a separate question, and it’s one for your accountant. I’ve written up the trade-offs in UK company vs personal ownership.

Certified and apostilled: what they actually mean

These two words get used interchangeably. They aren’t the same thing.

Certified means a person authorised to do so has seen your original document, taken a photocopy, and written on the copy that it’s a true likeness of the original, then signed and dated it with their name, position and contact details. In the UK that’s usually a solicitor or a notary. Abroad it’s usually a notary public. A scan you made yourself isn’t certified, no matter how clear it is.

Apostilled means the certification itself has been verified by the issuing country’s government, so that a foreign authority can trust the notary’s signature. In the UK this is done by the Legalisation Office, which attaches a stamped certificate to the document. An apostille costs £45 for the standard paper service, or £35 for an e-Apostille, and the standard service takes up to 25 working days plus postage. Fees and timings are published on GOV.UK (checked 25 August 2026). Other countries have their own apostille authority and their own fees.

You won’t always need an apostille. It tends to come up with corporate documents issued abroad, powers of attorney, and documents from countries where the receiving firm has no way to check the notary. Ask which of your documents need it before you send anything off, because 25 working days is a long time to discover you needed it.

Who asks for what

The same documents get requested several times by different parties, because each is separately supervised and each has to hold its own file. It’s duplication, and it’s unavoidable.

Your sourcer or buying agent takes an identity and address check before starting work, and asks about funds
Your conveyancing solicitor takes the full pack, including source of funds, and won’t release completion funds without it
Your lender, if you’re borrowing, takes its own version plus income evidence and often a larger deposit than a UK resident would need
Your UK bank or currency provider takes its own, and may query the transfer separately when the money moves

Every one of them must keep these records for five years after the transaction completes. That’s a legal retention period, not a filing preference.

Two things overseas landlords often miss

If you’ll be letting the property and living abroad, your letting agent or tenant is required to deduct basic rate tax from the rent before paying you, unless HMRC has approved you to receive it gross. The application is form NRL1i, and HMRC will refuse it if your UK tax filings aren’t up to date. Apply before the first tenancy starts, not after the first deduction surprises you.

Separately, when you eventually sell, a non-resident must report the disposal and pay any Capital Gains Tax due within 60 days of completion, even if there is no tax to pay. Both points are set out on GOV.UK (checked 25 August 2026). How either applies to you depends on your circumstances and your country’s treaty with the UK, so take this to an accountant rather than treating it as advice.

What to do next

Build the pack now, in one folder, in this order: passport, proof of address, source of funds evidence, company papers if applicable. Get the certifications done while you’re still searching. Ask each firm, in writing, exactly which documents they need certified and which need an apostille, because their answers will differ.

When I take on a client I tell you the full list at the start rather than drip-feeding requests, and I flag anything likely to need an apostille while there’s still time to get one. You can see how the rest of the purchase runs in the legal process step by step, and what I do at each stage on how it works.
