Corporate M&A Lawyer

Corporate M&A Lawyer | Advisory support from deal structuring to closing

Summary

Corporate M&A covers a range of transactions — share acquisitions, asset purchases, statutory mergers, and business transfers — each governed by different provisions of the Commercial Act (상법) and, where the target is a public company or the deal is large enough, the Fair Trade Act's merger notification rules (독점규제 및 공정거래에 관한 법률). The right structure depends on tax treatment, liability allocation, and whether shareholder or board approval thresholds can be met. Legal advisory work centers on due diligence findings, contract terms that allocate risk after signing, and clearing any regulatory approvals before or after closing.

Corporate M&A | Three common ways to structure an acquisition

The same business can change hands through a share deal, an asset deal, or a statutory merger. Each route has different consequences for liability, tax, and required approvals, so the choice should be made early, before due diligence begins.

Share Deal

Buyer acquires shares of the target company directly from existing shareholders

What transfers	Shares; target's liabilities stay with the company
Approval needed	Usually just seller/buyer agreement; board approval
Tax exposure	Seller pays capital gains tax on share transfer
Typical use	Clean handover of an entire ongoing business

Because the target company itself does not change, existing contracts, licenses and liabilities generally carry over automatically.

Asset Deal

Buyer purchases specific assets and selected liabilities, not the corporate entity

What transfers	Named assets/contracts only, by individual assignment
Approval needed	Board approval; shareholder approval if it is a transfer of substantially all business (상법 제374조)
Tax exposure	Corporate entity pays tax on asset sale; VAT may apply
Typical use	Carve-outs, buying part of a business, avoiding unwanted liabilities

Because liabilities do not transfer automatically, buyers can exclude specific risks, but each contract and permit may need individual consent to assign (민법 제449조 principles apply to contract assignment).

Statutory Merger

Two companies combine into one under the merger procedure in the Commercial Act

What transfers	Entire business, assets and liabilities by operation of law
Approval needed	Special resolution of shareholders' meeting (상법 제522조, 제434조)
Tax exposure	Can qualify for tax-deferred treatment if statutory requirements are met
Typical use	Combining group affiliates, larger strategic combinations

A merger requires creditor protection procedures, including public notice to creditors, before it becomes effective (상법 제527조의5).

Corporate M&A | Legal due diligence and what it actually changes in a deal

Due diligence is not a formality — findings routinely change the purchase price, the warranty package, or whether the deal closes at all. The scope should match the deal structure chosen.

What legal due diligence typically covers

A legal review generally covers corporate authority to sell, material contracts (change-of-control clauses in particular), litigation and regulatory history, employment and pension liabilities, and intellectual property ownership. Undisclosed contingent liabilities found late in the process are a common reason deals are repriced or restructured.

Red flags that affect deal terms

Change-of-control clauses in the target's key contracts can let counterparties terminate upon a share transfer, which may require pre-closing consents. Pending litigation, unresolved tax assessments, or labor disputes are usually addressed through price adjustment, escrow, or specific indemnities in the contract rather than being ignored.

Confidentiality and exclusivity before due diligence starts

Before sharing sensitive information, parties typically sign a non-disclosure agreement and, if a period of exclusive negotiation is needed, a letter of intent with a no-shop clause. These preliminary documents are usually non-binding as to the deal itself but binding as to confidentiality and exclusivity terms.

Corporate M&A | Structuring the share purchase or asset purchase agreement

The definitive agreement is where due diligence findings get translated into enforceable protections. Poorly drafted warranty and indemnity clauses are a frequent source of post-closing disputes.

Representations, warranties and indemnities

Sellers typically make representations about the accuracy of financial statements, absence of undisclosed liabilities, and title to the shares or assets. If a warranty turns out to be false, the buyer's remedy is usually contractual indemnification rather than automatically rescinding the deal, so the survival period and cap on liability negotiated in the contract matter significantly.

Price adjustment mechanisms

Purchase price is often set at signing but adjusted at closing based on a closing balance sheet, working capital targets, or an earn-out tied to future performance. Disputes over these mechanisms are common and are usually resolved through an independent accountant provision written into the agreement.

Conditions precedent to closing

Typical closing conditions include obtaining required regulatory clearances, third-party consents to assign key contracts, and confirmation that no material adverse change has occurred between signing and closing. Each condition should be drafted with a clear standard, since vague conditions create room for either party to walk away or delay closing.

Corporate M&A | Regulatory clearance and merger filings

Certain deals cannot close, or must be reported, until competition authorities and sector regulators sign off. Missing a filing deadline can expose the parties to corrective orders or fines.

Merger notification to the Fair Trade Commission

If the parties' combined assets or sales exceed the thresholds set by the Fair Trade Act, the transaction must be reported to the Korea Fair Trade Commission before or shortly after closing, and in some cases closing must wait until clearance is obtained (독점규제 및 공정거래에 관한 법률 제11조). Failing to file, or closing before clearance when a standstill applies, can result in corrective measures or fines.

Sector-specific approvals

Deals involving regulated industries — financial institutions, telecommunications, defense, or businesses handling personal data at scale — often require approval from the relevant sector regulator in addition to the general merger filing. These approvals can take longer than the deal timeline anticipates, so they should be scoped during early due diligence.

Foreign investment and inbound deal considerations

Where the buyer is a foreign entity, the acquisition may need to be reported under the Foreign Investment Promotion Act, and certain strategic sectors carry additional restrictions. These filings are usually administrative rather than discretionary approvals, but timing them correctly avoids delays at closing.

Corporate M&A | From initial consultation to post-closing integration

Initial consultation and structuring advice
We review the commercial objective and recommend whether a share deal, asset deal, or merger best fits the tax and liability profile involved.

Preliminary documentation
Drafting or reviewing the NDA and letter of intent, including exclusivity and deal-protection terms, before sensitive information is exchanged.

Due diligence
Legal review of corporate, contractual, labor, litigation and IP matters, coordinated with financial and tax advisors, producing a findings report that feeds into pricing and contract terms.

Negotiation and drafting of the definitive agreement
Negotiating representations, warranties, indemnities, price adjustment mechanisms and closing conditions on behalf of the client.

Regulatory filings and closing
Preparing and submitting any required merger notification or sector approval applications, satisfying closing conditions, and coordinating simultaneous closing deliverables.

Post-closing integration and dispute support
Advising on post-closing adjustments, warranty claims, and integration matters such as employment transfers or contract novation.

Corporate M&A | How advisory fees are typically calculated

Retainer for due diligence
Generally scoped based on the number of contracts, entities and jurisdictions to be reviewed, and the time required to produce a findings report.

Transaction fee for drafting/negotiation
Often calculated by deal complexity and expected negotiation hours rather than a flat percentage of deal value, though some engagements use a value-based fee for larger transactions.

Regulatory filing fee
Covers preparation of merger notifications or sector approval applications; complexity depends on the number of regulators involved.

Success-linked component
Where agreed, part of the fee may be tied to successful closing, structured within the bounds permitted for corporate advisory engagements.

Disbursements
Translation, notarization, and government filing fees are billed separately based on actual cost.

※ Costs vary depending on case complexity and specific circumstances; exact fees will be provided during consultation. No specific outcome is guaranteed.

Corporate M&A | Self-Check Before You Reach Out

1️⃣ For Buyers

Have you identified whether a share deal or asset deal better fits your liability appetite?
Do you know which of the target's contracts contain change-of-control termination rights?
Have you budgeted for merger notification filings if the deal size crosses the threshold?
Is your financing conditional on due diligence results?

2️⃣ For Sellers

Have you organized corporate records, material contracts, and litigation files for a data room?
Do you understand what representations and warranties you will realistically be able to make?
Have you considered the tax treatment of a share sale versus an asset sale?
Do any shareholders' agreements or bylaws require special approval for this sale?

3️⃣ Regulatory Readiness

Does the combined size of the parties trigger a Fair Trade Commission merger notification?
Is either party in a regulated sector requiring separate approval?
If the buyer is foreign, has foreign investment reporting been considered?
Is there a standstill period before closing that your timeline needs to account for?

4️⃣ Post-Signing

Are the conditions precedent in the agreement clearly measurable rather than vague?
Is there a mechanism to resolve disputes over closing price adjustments?
Does the indemnification cap and survival period reflect the risks found in due diligence?
Have employment and benefit obligations for transferring staff been addressed?

Frequently Asked Questions

Q. What is the difference between a share deal and an asset deal?

A. In a share deal, the buyer acquires the target company's shares, so the company continues to hold all of its existing assets and liabilities. In an asset deal, the buyer purchases specified assets and liabilities individually, which lets the buyer exclude unwanted liabilities but usually requires separate consent to assign contracts and permits.

Q. Do we need approval from the Fair Trade Commission for our deal?

A. A merger notification is required if the combined assets or sales of the parties exceed the thresholds set under the Fair Trade Act (독점규제 및 공정거래에 관한 법률 제11조). Whether the deal must wait for clearance before closing depends on which party is the larger of the two and the specific thresholds involved, so this should be checked early in the deal timeline.

Q. How long does legal due diligence usually take?

A. The timeline depends on the number of entities, contracts, and jurisdictions involved, as well as how organized the target's records are. Straightforward domestic share deals can be reviewed in a few weeks, while deals involving multiple subsidiaries or regulated industries typically take longer.

Q. What happens if a seller's representation turns out to be false after closing?

A. The buyer's typical remedy is an indemnification claim under the purchase agreement, not automatic rescission of the deal. The amount recoverable is usually limited by the cap and survival period the parties negotiated into the contract, so these terms should be reviewed carefully before signing.

Q. Is shareholder approval always required to sell a business?

A. It depends on the structure. A statutory merger requires a special shareholders' resolution (상법 제522조, 제434조), and an asset sale that amounts to a transfer of substantially all of the business also requires shareholder approval (상법 제374조). A sale of shares by individual shareholders generally does not require the target company's own shareholder approval.

Q. Can a deal be structured to defer taxes?

A. Certain statutory mergers and qualifying spin-offs can receive tax-deferred treatment if specific statutory requirements are met, but this depends heavily on the facts and should be reviewed together with tax advisors rather than assumed.

Q. What is an earn-out and why do disputes arise over it?

A. An earn-out ties part of the purchase price to the target's future performance after closing, often used when the buyer and seller disagree on valuation. Disputes commonly arise over how the relevant financial metrics are calculated post-closing, which is why the calculation method and any independent accountant mechanism should be defined precisely in the agreement.

Q. Does a letter of intent legally bind us to complete the deal?

A. Most letters of intent are non-binding as to the ultimate transaction, but binding as to specific clauses such as confidentiality, exclusivity, and allocation of due diligence costs. Whether a particular clause binds the parties depends on how it is drafted, so this should not be assumed from the document's title alone.

Q. What happens to employees when a business is sold in an asset deal?

A. In an asset deal, employees generally do not transfer automatically and their employment relationship with the target continues unless individually transferred with consent, whereas in a share deal employment relationships are unaffected because the employer entity does not change. Labor law treatment can vary depending on how the transaction is characterized, so this is typically reviewed as part of due diligence.

Q. Do we need a local M&A lawyer if the buyer or seller is a foreign company?

A. Cross-border deals often require coordinating Korean corporate, tax and regulatory filings with foreign counsel handling the other jurisdiction's requirements. A corporate M&A lawyer in Korea is generally engaged to handle the domestic due diligence, contract drafting under Korean law, and any Fair Trade Commission or foreign investment filings.
