Cross-Border Legal Due Diligence: How FLAI Does It

Foreign Legal Affairs Institute (FLAI) · Joowon Law Firm

Legal due diligence on a cross-border deal usually fails at the seam, not in the substance. Korean counsel delivers a competent Korean-law report; the board in Shanghai, Houston or Tokyo needs an answer to a different question — will this target clear our IPO sponsor's review, our lender's CP list, our CFIUS filing, our sanctions screen? FLAI closes that gap. Joowon's Korean-licensed attorneys perform the Korean-law review; FLAI's foreign counsel scopes the exercise around the foreign decision it must support, adds the U.S.-law and trade-compliance layer, and delivers the result in a form the foreign reader can act on.

1. Inbound: foreign investors acquiring or funding a Korean company

Beyond corporate, contract and litigation review, the items that most often move price or timing:

• Foreign investment reporting — pre-acquisition report under the Foreign Investment Promotion Act (외국인투자촉진법) Art. 5 (new shares) or Art. 6 (existing shares), post-closing registration under Art. 21; capital transactions FIPA does not cover (short-term shareholder loans, guarantees) fall under Foreign Exchange Transactions Act (외국환거래법) Art. 18.

• Merger control — Monopoly Regulation and Fair Trade Act (공정거래법) Art. 11; thresholds of KRW 300 bn / KRW 30 bn in worldwide assets or turnover (Enforcement Decree Art. 18), with Korean turnover of KRW 30 bn each where both parties are foreign; pre-closing notification and waiting period where the acquirer group is a 대규모회사 (KRW 2 tn).

• National core technology — Industrial Technology Protection Act (산업기술보호법) Art. 11-2 requires approval (state-funded R&D) or prior report (otherwise) before a foreign acquisition of a company holding a designated core technology. Semiconductors, displays, batteries and biotech are where this surfaces.

• Real estate held by the target — Real Estate Transaction Reporting Act (부동산거래신고법) Art. 8 (foreign acquisition report) and Art. 9 (permit zones); in a share deal that pushes foreign ownership past 50%, the target itself becomes a "foreigner" and must file a continued-holding report within six months (Art. 8(3)) — routinely missed.

• Employment — ordinary-wage (통상임금) exposure recalculated after 대법원 2024. 12. 19. 선고 2020다247190 전원합의체, which removed the "fixedness" requirement; illegal-dispatch direct-employment liability under 파견법 Art. 6-2; Serious Accidents Punishment Act (중대재해처벌법) Art. 4 duties, which since 27 January 2024 reach every employer with five or more employees.

• Data — Personal Information Protection Act Art. 28-8 governs cross-border transfers, including the acquirer's own post-closing access to Korean personal data from overseas.

One point we state expressly in every inbound report: Korea offers no third-party party-name search of pending litigation. The litigation review rests on the target's certified litigation list, its own court-record extracts, registry entries (provisional attachments, injunctions, mortgages on the 법인·부동산 등기), and credit-bureau data — and the report says so in terms a foreign reader can weigh.

2. Outbound: Korean companies acquiring in the United States

Where the target touches defense, semiconductors, critical infrastructure or sensitive personal data, diligence is a filing-strategy exercise as much as a risk review:

• CFIUS — 50 U.S.C. § 4565, 31 C.F.R. Part 800; mandatory declaration where the target is a TID U.S. business producing critical technologies (§ 800.401). Korea is not an excepted foreign state; no exemption applies.

• Export controls — EAR (15 C.F.R. Parts 730–774): ECCN classification of the target's products and technology, licensing history, deemed-export exposure for Korean-national employees (§ 734.13(b)). ITAR (22 C.F.R. Parts 120–130): DDTC registration (§ 122.1) and the 60-day advance notice of change to foreign ownership (§ 122.4(b)).

• Sanctions and anti-corruption — OFAC (31 C.F.R. ch. V), including the 50 Percent Rule and successor liability; FCPA (15 U.S.C. §§ 78dd-1 to -3, 78m(b)), where the DOJ/SEC Resource Guide treats pre-acquisition diligence as the test for successor exposure.

• Environmental — CERCLA § 107(a) (42 U.S.C. § 9607(a)) strict, joint and several owner/operator liability; bona fide prospective purchaser protection under § 9601(40) requires "all appropriate inquiries" (ASTM E1527-21 Phase I) completed before closing.

• Corporate and employment — DGCL §§ 251, 271; WARN Act (29 U.S.C. § 2101 et seq.) 60-day notice; state overlays such as California's non-compete bar (Bus. & Prof. Code § 16600).

• Korean-side filings — overseas direct investment report under 외국환거래법 Art. 18 and Chapter 9 of the FX Transactions Regulations before remittance; 산업기술보호법 Art. 11 where core technology moves outbound.

3. Listing and lender diligence on Korean subsidiaries

When a parent listing in Shanghai, Hong Kong, Tokyo or New York — or a syndicate lender — needs a legal opinion on its Korean subsidiary, the receiving counsel expects it in its own idiom: due incorporation and valid existence, verified paid-in capital, licenses and permits, material contracts and encumbrances, litigation, compliance, and the assumptions, qualifications and reliance language opinion practice requires. Joowon's Korean attorneys issue under Korean law; FLAI conforms scope, form and translation to what sponsor counsel and exchange review require, and handles sponsor Q&A directly. KYC and sanctions screening at intake — increasingly a client-side condition precedent — is built in.

How we scope and deliver

• Red-flag report (issue-only, materiality threshold agreed at kickoff) or full-scope report with executive summary. Most inbound mid-market deals want the former; listing opinions require the latter.

• Every material finding is mapped to a transaction mechanism — specific indemnity, condition precedent, closing deliverable, price adjustment, escrow or holdback, or W&I exclusion — rather than left as a risk description.

  FLAI's foreign-counsel practice has supported multi-billion-dollar semiconductor, hydrogen, battery and pharmaceutical projects, and its director serves as UNCITRAL's CLOUT contributor for the Republic of Korea and in ABA International Law Section committee leadership. That combination is the point: diligence written by people who also draft the SPA, run the arbitration when it goes wrong, and report the case law afterward.
