Name and passport: one spelling across every deal document

A cross-border property purchase rests on one assumption: the person on the reservation, the person in the contract, the sender of the payment and the owner in the register are the same human being. The proof is the spelling of a name and a set of passport details. While they match letter for letter, nobody asks. The moment they diverge, somebody in the chain — a bank, a developer, a lawyer, a registry clerk — is obliged to look into it, and the deal pauses. This page explains where mismatches come from, where they surface, and how to check everything before the first payment leaves your account.

The single source of truth is your current passport

The rule is simple: the reference spelling is the Latin script in the machine-readable zone of your current passport — the two lines at the bottom of the data page. Not the way you usually write your name in emails. Not what is embossed on your bank card. Not what an agent typed in the first message.

The reason is verifiability. Every other party holds only a copy of your passport, and that copy is what they check against. If the contract says something different, the reviewer has no way to tell a typo from a different person — so they have to ask.

Which leads to the practical rule: do not bend the passport to fit the documents. Bend the documents to fit the passport, even if the passport spelling looks wrong to you.

Where mismatches come from

Almost never from carelessness. Usually from how documents are made.

Where the mismatch surfaces

It almost never surfaces where it was created. It surfaces at the next step, usually once money is already moving.

1. The reservation. The first document carrying your name, and typically the one filled in fastest — an error here propagates through the whole chain.
2. The SPA. Buyer details are usually copied over from the reservation. If the error came from there, it is now baked into the main contract of the deal.
3. The power of attorney, if you are buying remotely. A document giving someone the right to act for you gets read carefully: it must point to exactly the same person as the SPA.
4. The bank transfer. The most common place where everything stops. The sender name on the payment is checked against the buyer name on the invoice and the contract. A transfer may be delayed, returned or queried — which of those happens depends on the bank.
5. Title registration. The final point. Here the name enters the ownership record and stays there for years. An error that reaches this stage will come back at resale, at inheritance or whenever you need a certificate.

The logic is straightforward: the later a mismatch is found, the more documents have to be redone, and the more often that requires signatures from people who are now hard to gather.

A pre-payment consistency check

This is the kind of task where twenty minutes saves weeks. Open the passport data page next to every draft you have and work through the list.

On signatures specifically: the point is recognisability, not graphological precision. Sign every deal document the same way, and the same way as in your passport. If you normally sign inconsistently, pick one version for the whole deal and stay with it.

What to do if a mismatch already exists

First and most important: do not rewrite documents after the fact and do not smooth the details so the difference stops being noticeable. A mismatch is not misconduct — it is a fact of your biography that has to be explained and evidenced.

1. Stop the irreversible steps. Do not send the payment and do not sign the next document until the name question is settled. Money sent under mismatched details is the expensive part of the problem.
2. Pin down exactly what differs. One letter, the passport number, the whole surname, the field order — the fix depends on it.
3. Gather the documents that connect the versions. The old passport, a marriage or name-change certificate, a confirmation from the issuing authority. These are what turn "two names" into "one person".
4. Ask in writing. Ask the developer and the bank what they need for your specific situation. Requirements differ by bank, by developer and by stage of the deal; there is no single universal list.

Do not order an apostille for Cambodia by default

The HCCH status table updated on 30 June 2026 does not list Cambodia as a Contracting Party to the 1961 Apostille Convention. An apostille should therefore not be treated as a universally sufficient treaty route for using a foreign marriage, divorce or name-change record in Cambodia.

Before paying for translation, notarisation or consular legalisation, obtain the actual recipient's written document route. Confirm whether it wants the original or a certified copy, the required translation language, who must certify the translation, and which authentication sequence will be accepted by the bank, developer, lawyer and cadastral office.

5. Correct things transparently. Changing details in a signed document is done by an addendum or another written instrument, not by swapping a page. Your deal lawyer will name the right form.
6. Walk the whole chain. Having fixed the SPA, revisit the reservation, the power of attorney, the payment details and everything heading to registration. A single isolated correction usually creates a new mismatch somewhere else.

Keep a correction log until the last downstream record is closed

For every discrepancy, record the incorrect value, the accepted value, all affected documents, the person responsible for the correction, the date of written approval and the current signed version. Attach the email, addendum or other instrument by which the relevant participant accepted the change.

Do not close the item merely because the SPA was amended. Recheck the reservation, addenda, power of attorney, invoices, receipts, bank customer profile and the registration filing. The issue is closed only when the old value no longer travels downstream without an explanatory document.

A special case: the passport changes mid-installments

Buying off-plan stretches over years, so replacing a passport in the middle of a payment schedule is ordinary rather than rare. The mistake is always the same: the buyer renews the passport and simply keeps paying without telling anyone.

The right sequence is to notify the developer and the lawyer as soon as the new document is in hand and before the next payment, and to keep a copy of the old passport — it is the link between the already-signed documents and you. If the deal runs on a power of attorney, check whether that document is tied to the old passport number.

After a passport replacement, ask the bank to update its customer file before the next transfer. FATF Recommendation 10, in the October 2025 edition, identifies doubts about the veracity or adequacy of previously obtained identification data as a trigger for customer due diligence. It does not create one document list for every bank, but it explains why notifying the developer does not update the bank automatically: obtain written confirmation that the new passport has been accepted and keep it with the old copy.

We deliberately do not print a ready-made notification form or a list of required papers: that is set by the developer, the bank and the lawyer on your deal, and we cannot confirm a single standard.

Frequently asked questions

Which spelling of my name counts as the correct one?

The one in the machine-readable zone of your current passport, letter for letter. It is the only version every party to the deal can verify: the developer, the bank, the lawyer, the registry. Every other spelling — from an old passport, a driving licence, the way you sign your emails — is secondary. Do not bend the passport to fit the documents; bend the documents to fit the passport.

My passport was replaced in the middle of the deal. What now?

Tell the developer and your lawyer straight away, before the next payment rather than after it. Keep a copy of the old passport: it is what links the already-signed documents to you. If the transliteration or the number changed, the link between the old and new details has to be recorded in writing — the exact form of that confirmation is set by the developer, the bank and the lawyer on your deal, and we cannot confirm a single standard template.

Should I include a patronymic or middle name?

If it does not appear in the Latin-script section of your passport, do not add it to deal documents on your own initiative — you would create a mismatch where there was none. If a form insists on it, show the form to your lawyer and fill it so that the given name and surname match the passport exactly, with the extra name in its own field rather than glued onto the given name.

Does a single-letter difference really matter?

It matters enough to check in advance. One letter can be enough for a bank transfer to be returned, for a payment not to be recognised as yours, or for questions at registration — the actual outcome depends on the bank, the developer and the stage of the deal. Checking the spelling before the first payment is far cheaper than correcting a chain of documents afterwards.
