How to verify a Cambodian company or partner

Short answer

Verification of a Cambodian counterparty is a short list of concrete checks: confirm the company on the Ministry of Commerce register, confirm its patent tax is paid, ask for tax clearance, check any land against the land title, and run the anti-corruption questions before money moves. Each takes a day and prevents the disputes that take a year.

Start with the register

The Ministry of Commerce business registration system is the place to start, and access now runs through CamDigiKey. For an entity registered before 31 July 2026, the account ownership claim has to be completed for filings to be made, which is itself a useful test: a counterparty who cannot produce a working CamDigiKey access is telling you something.

What to establish from the register, and to keep on file:

Legal name, registration number, registered address and registered business activity.
Shareholders and directors, and whether the shareholding matches what you were told.
Registration date, and whether the annual declaration has been filed for each anniversary since.
Any change of name or activity, and the date it took effect.

The annual declaration is the quiet indicator. It is due in the three months before the registration anniversary with a 15-day grace period, and three consecutive missed filings move a company to inactive status and place its directors and shareholders on a watch list. A company that has been filing on time is a company with a working bookkeeper.

Tax status and the paper trail

Two checks, both quick.

The patent tax. The annual business licence tax per activity, due 31 March. Ask for the most recent payment receipt and the registration certificate that shows the activities on which the tax is paid. A company trading in two activities but paying one patent tax is telling you that part of the business is undeclared.
Tax clearance. A current tax clearance certificate, or a confirmation that the company is up to date with the General Department of Taxation, tells you whether there is a dispute on the other side of the Ministry of Economy and Finance.

For a distributor, also ask for the import and export licence, the customs registration details, and the last three customs declarations. A partner who will not show you their declarations has no track record to show.

Land, and the premises actually used

If the counterparty occupies or leases land, the chain has to hold.

For a lease: is it registered, with what term, and does the landlord hold clean title?
For owned land: is the title in the company’s name, unencumbered, and consistent with the premises being used?
For a factory: does the operating licence match the activity, and does the site sit inside the right zone?

The integrity questions, before money moves

These are the questions that protect the transaction rather than the balance sheet, and they are asked of the people, not only the paperwork.

Who signs, and under what authority? The signatory should be named in the register, and the contract should be signed by someone with authority to bind the company.
How is the counterparty paid? A fee that is unusually high, a payment to a third country, a request for cash or for a crypto wallet, or an insistence on advance payment without any credit history are all reasons to stop and ask questions.
Is anyone paying a commission? If a third party is facilitating the deal, ask what they are paid and by whom. That answer belongs in the file.
Does the counterparty answer commercial questions? A prospective distributor who cannot answer basic questions about their own market, their customers or their landed cost is not going to manage your business.

The 2026 Investment Climate Statement for Cambodia records corruption as an investor concern and the 2025 statement described the anti-corruption framework, including the role of the Anti-Corruption Commission. A written, referenced, proportionate integrity check is not paranoia; it is the part of the file that survives an audit.

Disputes and the limits of the register

Two limits are worth stating plainly. The business register shows existence and particulars, not solvency, not trading history and not whether a company is involved in litigation. And because Cambodia has no commercial court, checking for a commercial dispute history is harder than in some markets: the practical route is the Ministry of Commerce, the Cambodian Chamber of Commerce and a search of published judgments, and a reference from a previous counterparty who has worked with them.

Which is why the strongest check is usually not documentary. A supplier or distributor that has been trading for years with local customers will have a reference you can call, and that reference is worth more than a certificate.

Questions investors ask

How do I check whether a Cambodian company is real?

Start with the Ministry of Commerce register: legal name, registration number, address, activity, shareholders and directors. Then check that the annual declaration has been filed for each anniversary since registration, and that the patent tax has been paid for the activity you are being asked to buy. A company that cannot produce a working CamDigiKey access is telling you something.

What is the patent tax and why does it matter in due diligence?

It is the annual business licence tax per activity, due 31 March. It matters because a company trading in two activities but paying one patent tax is operating partly outside the system, and because payment evidence tells you the company has been filing and accounting on time.

What is a tax clearance certificate in Cambodia?

It is confirmation from the General Department of Taxation that a company is up to date with its obligations. Requesting one is a normal part of onboarding a partner and it is quick; a refusal to provide it is informative.

Can I check whether a company is in litigation?

Only to a degree. The business register shows existence and particulars, not litigation history, and Cambodia has no commercial court, so there is no single searchable commercial judgment database. Use published judgments, Ministry of Commerce and Chamber of Commerce channels, and a reference from a previous counterparty.

Should I use a third-party facilitator or agent?

Often, because they know the market. Ask what they are paid and by whom, and put the answer in the file. An agent who is paid by both sides, or who asks for payment outside the contract, is a risk you do not need to carry.

How long does a proper check take?

The documentary checks are a few days: register particulars, patent tax evidence, tax clearance, and the land position if property is involved. The interviews and reference calls take longer because they depend on other people’s calendars, and they are usually the part that finds the problem.

Is a nominee director acceptable?

We would not recommend it. A nominee who appears on the register takes on the legal exposure of a director while carrying none of the decision-making, and it complicates every later transaction, audit and tax position. If you need local presence, use a genuine local director or a local entity with a real shareholder.

What should I do if a check raises a concern?

Do not proceed and do not accuse. Write down what you found, ask the counterparty to explain it, and take advice from Cambodian counsel before you take any step. Most concerns have an innocent explanation; the ones that do not are cheaper to walk away from now than to unwind later.
