What Should Foreign Investors Know Before Buying Shares in a Korean Company?

Short Answer

Before buying shares in a Korean company, foreign investors should review the transaction structure, target company records, share ownership, share transfer restrictions, foreign investment filing requirements, tax issues, and whether a shareholders’ agreement is needed.

A Korean share acquisition is not only a payment issue. The investor should confirm who legally owns the shares, whether the shares can be transferred, whether corporate approvals are required, and whether the investor will have meaningful rights after closing.

In practice, the safest approach is to conduct due diligence, prepare a clear share purchase agreement or share subscription agreement, complete foreign investment and remittance procedures properly, and secure governance and exit rights before closing.

Why Foreign Investors Buy Shares in Korean Companies

Foreign investors may buy shares in a Korean company to enter the Korean market, acquire a strategic stake, invest in a startup, work with a Korean partner, or participate in management.

A share acquisition may involve:

• purchasing existing shares from a shareholder;
• subscribing for newly issued shares;
• acquiring a minority stake;
• acquiring control of the company; or
• making a strategic investment with business cooperation.

Each structure has different legal, tax, corporate, and foreign investment implications.

Existing Shares vs. New Shares

The first issue is whether the investor is buying existing shares or subscribing for new shares.

If the investor buys existing shares, the purchase price is usually paid to the selling shareholder. The company itself does not receive the investment money.

If the investor subscribes for new shares, the money is paid into the company as capital, and existing shareholders may be diluted.

This distinction affects:

• who receives the money;
• what agreement is needed;
• corporate approvals;
• foreign investment filing;
• tax treatment; and
• post-closing shareholder rights.

Foreign investors should clearly distinguish between a share purchase agreement and a share subscription agreement.

What Due Diligence Should Be Done?

Before buying shares, the investor should conduct legal and financial due diligence.

At minimum, the investor should check:

• corporate registry records;
• articles of incorporation;
• shareholder register;
• board and shareholder resolutions;
• financial statements;
• tax issues;
• major contracts;
• licenses and permits;
• litigation or disputes;
• debts or guarantees;
• pledges or security interests over shares; and
• intellectual property.

The investor should confirm not only whether the company is commercially attractive, but also whether the shares can be legally transferred and whether there are hidden liabilities.

---

Who Owns the Shares?

The investor should confirm who legally owns the shares.

In Korea, the shareholder register is especially important. Even if shares are transferred between the parties, the buyer may not be able to assert shareholder rights against the company unless the shareholder register is properly updated.

The investor should also check whether share certificates have been issued. If share certificates exist, possession and delivery of the certificates may become important. If the company has not issued share certificates, the transfer process and shareholder register update should be reviewed carefully.

Key items to check include:

• current shareholder register;
• prior share transfer documents;
• share certificates, if issued;
• whether shares are certificated or uncertificated;
• board or shareholder approvals;
• nominee or beneficial ownership issues;
• pledges, security interests, or attachments over shares; and
• whether the seller has authority to sell.

If the seller does not have clear ownership or authority, the foreign investor may face serious problems after closing.

---

Are There Share Transfer Restrictions?

Yes, there may be.

Share transfers may be restricted by the company’s articles of incorporation, board approval requirements, existing shareholders’ agreements, investment agreements, or industry-specific regulations.

Common restrictions include:

• board approval;
• right of first refusal;
• consent rights;
• lock-up periods;
• tag-along or drag-along rights;
• put or call options; and
• foreign ownership restrictions.

If the articles of incorporation require board approval for a share transfer, the investor should confirm whether that approval is obtained before or at closing.

Before signing, the investor should review both the company’s corporate documents and any agreement affecting the shares.

---

Is Foreign Investment Filing Required?

Potentially, yes.

If the share acquisition qualifies as foreign investment, the investor may need to complete foreign investment notification or related reporting.

This may depend on:

• investment amount;
• shareholding percentage;
• voting rights;
• whether the investor appoints or dispatches officers;
• whether the shares are existing or newly issued;
• whether the target is already foreign-invested; and
• whether the business sector is restricted or regulated.

In many cases, foreign investment notification is generally handled before the investment, although certain transactions may allow post-acquisition reporting within a statutory period. Foreign investors should confirm the filing requirements before remitting funds or closing the transaction.

Proper foreign investment records may later affect bank remittance, dividends, share sale proceeds, foreign-invested company registration, and visa-related planning.

---

Does the Business Sector Matter?

Yes.

Some industries in Korea may be restricted, regulated, or subject to licensing requirements. Even if the foreign investor can acquire shares, the company’s actual business may require licenses, permits, registrations, or government approvals.

This may be relevant in industries such as:

• food, fisheries, agriculture, or cosmetics;
• finance or insurance;
• logistics and transportation;
• telecommunications or media;
• healthcare or medical-related services;
• education;
• real estate-related businesses; and
• other regulated sectors.

If the target company operates in a regulated sector, the investor should review whether the foreign share acquisition affects licenses, approvals, foreign ownership limits, or reporting obligations.

---

What Agreement Should Be Used?

The required agreement depends on the structure.

If the investor buys existing shares, the parties usually use a share purchase agreement. This should cover the shares, purchase price, closing conditions, seller’s ownership, representations and warranties, tax responsibility, foreign investment filing cooperation, and remedies for breach.

If the investor subscribes for new shares, the parties may use a share subscription agreement or investment agreement. This should cover the number and type of new shares, subscription price, payment date, corporate approvals, use of proceeds, foreign investment filing, and post-closing shareholder rights.

If the investor will remain involved after closing, a shareholders’ agreement may also be needed.

---

Should a Shareholders’ Agreement Be Signed?

Often, yes.

A foreign investor, especially a minority or strategic investor, should consider a shareholders’ agreement to protect post-closing rights.

Important provisions may include:

• board seat or observer rights;
• information rights;
• reserved matters;
• dividend policy;
• transfer restrictions;
• right of first refusal;
• tag-along and drag-along rights;
• anti-dilution protection;
• exit rights;
• confidentiality; and
• dispute resolution.

Without a shareholders’ agreement, the investor may own shares but have limited practical control, information rights, or exit leverage.

---

What Tax and Remittance Issues Should Be Reviewed?

Tax and remittance issues should be reviewed before closing.

Depending on the transaction, issues may include capital gains tax, securities transaction tax, withholding tax, tax treaty application, valuation, and future taxation of dividends or exit proceeds.

For foreign sellers or foreign investors, Korean tax rules and treaty issues may affect withholding, reporting, and payment procedures. The exact tax treatment should be reviewed with tax professionals before closing.

The remittance structure should also be documented carefully. The investor should preserve clear records showing:

• remitter;
• recipient;
• amount;
• purpose of payment;
• transaction agreement;
• foreign investment filing records, if applicable; and
• tax-related documents.

Poor documentation may create problems later when the investor seeks dividends, share sale proceeds, or other outbound remittance from Korea. Banks may also review whether future remittances are supported by proper transaction documents and tax records.

---

What Happens After Closing?

After closing, the parties should complete necessary updates and filings.

Post-closing steps may include:

• updating the shareholder register;
• issuing or updating share certificates, if applicable;
• completing foreign investment reporting or registration;
• updating tax and accounting records;
• implementing the shareholders’ agreement; and
• maintaining closing documents.

In Korea, a simple shareholder change does not always require commercial registry update. However, if the transaction involves new share issuance, capital increase, director change, or other registered matters, additional corporate registry filings may be required.

Signing and payment are not the end of the process. Proper post-closing documentation is important for future dividends, exit, audits, and remittance.

---

What If the Seller or Company Refuses to Cooperate After Closing?

If the seller, company, or other shareholders refuse to cooperate after closing, the investor’s options depend on the contract and corporate structure.

Possible responses may include:

• reviewing the share purchase agreement or investment agreement;
• enforcing closing obligations;
• requesting shareholder register updates;
• claiming breach of contract;
• seeking damages;
• pursuing litigation or arbitration; or
• considering provisional measures where necessary.

This is why the transaction documents should clearly define closing deliverables, cooperation obligations, post-closing filings, and remedies for breach.

---

What Should Foreign Investors Check Before Signing?

Before buying shares in a Korean company, foreign investors should check:

• whether they are buying existing shares or new shares;
• who legally owns the shares;
• whether share certificates have been issued;
• whether the shareholder register can be updated;
• whether transfer restrictions apply;
• whether corporate approvals are required;
• whether foreign investment filing is required;
• whether the business is regulated;
• whether due diligence has been completed;
• whether tax and remittance issues have been reviewed;
• whether a shareholders’ agreement is needed; and
• whether exit rights are properly addressed.

This checklist should be completed before funds are remitted or closing occurs.

---

Conclusion

Before buying shares in a Korean company, foreign investors should carefully review the transaction structure, target company records, share ownership, share transfer restrictions, foreign investment filing, tax issues, and post-closing documents.

A properly drafted share purchase agreement, share subscription agreement, investment agreement, or shareholders’ agreement can help protect the investor’s rights and reduce future disputes.

For foreign investors, the safest approach is to conduct due diligence first, confirm share ownership and transfer requirements, document the transaction clearly, handle foreign investment and remittance procedures properly, and secure governance and exit rights before closing.
