A power of attorney is a private document, so notarization comes first.

There is the first thing you need to understand when processing a power of attorney. A power of attorney is a private document written by the company itself.

I previously explained the difference between official and private documents in another article, but a power of attorney is a typical private document. Because it is a document created by a company, not a document issued by a government agency, you cannot receive an Apostille right away. It must be notarized first.

Notarization is the step where the notary public confirms that this power of attorney has been prepared in due process. Only after receiving notarization can you proceed to Apostille from the Ministry of Foreign Affairs or confirmation from the consulate. So, a power of attorney has one more step in the process than an official document, and there is more to prepare.

The power of attorney will be processed after the signature is notarized. (Original power of attorney, company seal certificate, law firm power of attorney, etc.)

Typical situations where a power of attorney is required

The situations in which a power of attorney is needed for overseas transactions are more diverse than you might think. Let's look at some representative cases.

The most common is delegation of sales authority. This means that a Korean company delegates the authority to sell a specific product to a local importer or seller. This serves as the basis for confirming whether the company is qualified to officially sell our products locally. It is often required for export of cosmetics, medical devices, and various consumer goods.

Next, a power of attorney is required during the process of establishing a local corporation or opening a branch. When establishing a local company or appointing or changing a branch manager, documentation is required showing that the headquarters delegates relevant authority to a specific person. This power of attorney must be certified before the local registration process can proceed.

In addition, when entrusting a specific task locally to an agent, a certified power of attorney must be submitted to prove the authority.


Depending on the country of submission, is it Apostille or consular authentication?

Like other documents, the procedures for a power of attorney differ depending on whether the submitting country is a signatory to the convention.

If the submitting country is a signatory to the Apostille Convention, the Apostille will be received after notarization. This includes the United States, China, Russia, and most European countries. If the country is not a member, it must be notarized, confirmed by the consulate, and even certified by the embassy of that country. This includes some countries in the Middle East, such as the UAE.

Therefore, before processing a power of attorney, you must first check which country it is being submitted to in order to accurately follow the procedure.

Points to note unique to power of attorney, renewal cycle

An area that requires special attention in power of attorney is the renewal cycle. This part stands out from other documents.

A power of attorney to sell often must be reissued and certified at certain intervals in accordance with local law. For example, some countries require powers of attorney to be renewed every few years. Just verifying and submitting it once is not the end. When renewal time comes, you must notarize, authenticate, and submit the new power of attorney again to maintain local transactions.

If you miss the renewal deadline, your local selling authority may expire and your transactions may be disrupted. Therefore, if you are a company that continues to deal with clients, it is important to manage the renewal time for each power of attorney.


Frequently Asked Questions

Q. Can’t I just fill out the power of attorney and send it?

In overseas transactions, it must be possible to verify locally whether the power of attorney is an official document.

Usually, a power of attorney written in the language requested by the submitting country will be notarized and Apostilleed (confirmed by the consulate).

Q. Why do I need to get the power of attorney notarized first?

This is because the power of attorney is a private document written by the company itself. Unlike official documents, you cannot receive an Apostille right away, and you must first go through the notarization stage where a notary public confirms the legitimacy of the writing.

Q. In what situations is a power of attorney required?

This is mainly required when delegating sales authority to a local importer or seller, establishing a local corporation, appointing or changing a branch manager, or entrusting work to a local agent. It is often used throughout import/export and overseas expansion.

Q. Once the power of attorney is verified, can I continue to use it?

Q. Are the procedures different depending on the country of submission?

Yes. If you are a country that has signed up to the convention, you will receive an Apostille after notarization.
