The Oligopoly Structure: How the "Big Four" Operated

Between 1953 and the early 2010s, an estimated 160,000 to 200,000 children were sent from South Korea abroad. This system did not develop as an informal network of charities; it was an exclusive, state-licensed oligopoly managed by the Ministry of Health and Social Affairs (now the Ministry of Health and Welfare) and executed through four private social welfare foundations:

1. Holt Children’s Services (홀트아동복지회)

2. Social Welfare Society / Korea Welfare Services (대한사회복지회 - SWS / KWS)

3. Korea Social Service (한국사회봉사회 - KSS)

4. Eastern Social Welfare Society (동방사회복지회 - ESWS)

Institutional Mechanisms & Collaboration

• The Special Adoption Act of 1976 and the Quota System: Under President Park Chung-hee’s authoritarian regime, the 1976 law codified intercountry adoption into formal state policy. The government issued exclusive operating licenses to these four agencies, explicitly barring other non-governmental organizations from processing international adoptions. The Ministry of Health and Social Affairs established annual adoption quotas and geographical allocations, assigning specific receiving nations and Western agency partners to each of the four agencies to prevent unmanaged competition.

• The "Orphanization" Protocol (Gi-a / 기아): To expedite emigration and satisfy foreign visa statutes (specifically U.S. Immigration and Nationality Act orphan definitions under IR-3 and IR-4 visas), agencies and municipal ward offices systematically bypassed standard parental consent tracking. Children with known living relatives, impoverished biological parents, or unwed mothers were legally erased from their families of origin and entered onto newly fabricated, solo family registries (hojeok) as abandoned foundlings (gi-a). This administrative erasure stripped the child of legal lineage, creating "clean paper orphans" cleared for expedited placement.

• Child Intake Pipelines: The agencies maintained formal intake networks across South Korea:

  • Maternity Shelters & Clinics: Facilities for unwed mothers (such as Ae Ran Won) were closely tied to adoption agencies, which funded or subsidized maternal care in exchange for infant relinquishment agreements signed under intense social and financial distress.

  • Social Cleansing Institutions: Investigative records and historical state archives confirm that during the 1970s and 1980s, agencies (notably ESWS and Holt) accepted children transferred from municipal holding facilities and forced-confinement camps, such as the Brothers Home (Hyeongje Bokjiwon) in Busan and Namkwang Orphanage, often paying per-child subsidies or intake fees.

• Economic and Social Substitution: Under both the Park Chung-hee and Chun Doo-hwan administrations, transnational adoption was wielded as a multi-purpose apparatus: it served as population control, reduced state fiscal burdens by substituting private foreign placement for domestic welfare infrastructure, and generated foreign currency reserves through substantial processing fees and mandatory foreign donations paid by Western agencies and adoptive parents.

In-Depth Profiles of the Big Four Agencies

1. Holt Children’s Services (홀트아동복지회)

• Founders & Key Figures:

  • Founded by Harry Holt (an evangelical farmer from Creswell, Oregon) and his wife, Bertha Holt.

  • Following Harry Holt’s death in 1964, Bertha Holt oversaw operations alongside their daughter, Molly Holt, who served as a longtime nurse, director, and chairperson of the board, heavily directing the Ilsan Center until her death in 2019.

• Establishment & Institutional Evolution:

  • Initiated in 1955 after Harry Holt lobbied the U.S. Congress for the passage of the "Holt Bill" (a Special Act allowing him to adopt eight mixed-race Korean War orphans simultaneously).

  • Formalized in Korea in 1956 as the Holt Adoption Program.

  • Pioneered proxy adoption, allowing prospective Western parents to be granted legal custody in Korean courts via an agency power of attorney without traveling to South Korea.

  • The 1976/1977 Corporate Split: In response to Park Chung-hee’s directives mandating that foreign social welfare agencies operating in Korea register as independent Korean foundations headed by Korean nationals, the organization split into two legally distinct entities:

    • Holt Children’s Services, Inc. (Holt Korea): The domestic Korean social welfare foundation controlling in-country intake, foster networks, and legal surrenders.

    • Holt International Children’s Services: The U.S.-based placement agency based in Eugene, Oregon.

• Historical Placement Footprint: The largest sender of Korean children globally, primarily placing children in the United States, Norway, Denmark, France, and Germany.

• Historical Services: Mass overseas adoption processing, operation of reception nurseries, temporary foster care networks, and the Ilsan Center (a permanent residential asylum for disabled children and adults).

• Current Operations & Status: Active. It operates as one of South Korea's largest social welfare NGOs. Its primary activities have shifted toward domestic adoption processing, residential and vocational facilities for people with developmental disabilities, single-mother shelters (e.g., Morning Garden), elderly welfare centers, and post-adoption search coordination for adult adoptees.

2. Social Welfare Society / Korea Welfare Services (대한사회복지회 - SWS / KWS)

• Founders & Key Figures:

  • Originated from the Child Placement Service (CPS / 대한양연회 - Daehan Placement Service), established in 1954 under direct guidance from the South Korean Ministry of Health and Social Affairs to manage post-war relief.

  • Transitioned into a private foundation under Korean civic leaders and medical professionals.

  • Longtime medical director Dr. Cho Byung-kook served as chief pediatrician at the SWS central nursery in Seoul for decades, personally conducting intake examinations for tens of thousands of infants bound for overseas transit.

• Establishment & Institutional Evolution:

  • Reorganized from the state-run Child Placement Service into a private entity in 1965, formally adopting the name Social Welfare Society (SWS) in the 1970s.

  • Later adopted the English operating name Korea Welfare Services (KWS).

• Historical Placement Footprint: SWS held an effective operational monopoly on placements to Sweden through its exclusive partnership with Adoptionscentrum, while also maintaining large placement corridors to the United States, Canada, and Australia.

• Historical Services: Operating large temporary holding nurseries (predominantly its central facility in Yeoksam-dong, Gangnam-gu, Seoul), managing urban foster families, and processing intercountry adoption dossiers.

• Current Operations & Status: Active. Maintains child and infant shelters, residential homes and vocational training centers for single mothers, rehabilitation clinics for children with severe physical disabilities, senior community centers, domestic adoption services, and post-adoption record retrieval services.

3. Korea Social Service (한국사회봉사회 - KSS)

• Founders & Key Figures:

  • Founded in 1964 by Baek Keun-chil (Kun Chil Paik).

  • Paik was an educated social worker who had studied social administration in the United Kingdom and previously directed the state-affiliated Child Placement Service (CPS) before establishing KSS as an independent agency.

• Establishment & Institutional Evolution:

  • KSS was unique among the Big Four as an entirely secular, indigenous Korean social welfare organization founded without foreign missionary backing or Western directorship.

  • Operated with a smaller administrative infrastructure and a strictly curated network of European partners.

  • Maintained a complex, bifurcated documentation practice: internal Korean-language intake ledgers and foster logs were routinely archived separately from the abbreviated or altered English-language medical and background summaries forwarded to foreign partner agencies.

• Historical Placement Footprint: Handled the vast majority of adoptions to the Netherlands (partnered with Wereldkinderen), Denmark (partnered with Adoption Center), and Switzerland (partnered with Terre des Hommes), alongside select U.S. adoption entities (including Welcome House, Lutheran Social Services, and Family/Foreign Adoption Consultants).

• Historical Services: Intercountry placement, small reception homes, foster care oversight, and local community-based social development.

• Current Operations & Status: Closed to international adoption. KSS ceased overseas adoption operations in 2011–2012. The legal entity remains operational strictly as a general domestic social welfare foundation; it does not process new adoptions. It currently maintains its historical adoption paper archives and processes post-adoption file reviews and background search requests.

4. Eastern Social Welfare Society (동방사회복지회 - ESWS)

• Founders & Key Figures:

  • Founded in 1972 by Dr. Kim Ouk-hyan (Kim Uk-hyun / Kim Duk-whang), a former high-ranking bureaucrat within South Korea's Ministry of Health and Social Affairs.

  • Following his tenure, his daughter, Kim Jin-sook, and direct family members retained executive governance and chair positions on the foundation's board of directors.

• Establishment & Institutional Evolution:

  • Established initially as the Eastern Child Welfare Society (ECWS) / Korea Christian Crusade.

  • Leveraging founder Kim Ouk-hyan’s prior administrative connections within the Ministry of Health and Social Affairs, ESWS rapidly acquired large quota allocations, competing directly with Holt and SWS despite entering the industry nearly two decades later.

• Historical Placement Footprint: Partnered extensively with U.S. placement agencies (such as Wide Horizons for Children, Children’s Home Society, Dillon International, and Adoption Advocates International), alongside government-approved receiving agencies in Australia and Scandinavia.

• Historical Services: Large-scale international placement processing, comprehensive foster mother systems, pediatric holding facilities, and institutional alliances with maternity homes.

• Current Operations & Status: Active. Operates domestic adoption services, maternal welfare institutions (including residential housing and post-natal care facilities for unwed mothers), welfare complexes for adults and children with developmental delays, daycares, elderly care centers, and post-adoption search departments.

Legislative Overhaul and the Truth and Reconciliation Findings

The operating framework of the Big Four has been fundamentally dismantled and reorganized through structural legal changes and state-level investigations:

1. The 2011/2012 Special Adoption Act Revisions

• Judicialization: Stripped private agencies of the legal authority to unilaterally finalize adoptions. All domestic and international adoptions were mandated to undergo formal adjudication and approval in the South Korean Family Court.

• Mandatory Birth Registration: Required that a child's birth be officially registered in civil records before an adoption could proceed, sharply curbing the historic practice of immediate "orphanization" and the creation of fictitious foundling files.

2. Findings of the Truth and Reconciliation Commission (March 2025)

Following legal petitions submitted by adult adoptees from Europe, North America, and Australia, South Korea’s Truth and Reconciliation Commission (진실·화해를위한과거사정리위원회) concluded a multi-year investigation into the agencies and the state:

• State and Agency Complicity: The Commission formally ruled that the South Korean government and the Big Four agencies systematically violated human rights.

• Systemic Malpractice Confirmed: The findings documented state-sanctioned fabrication of hojeok registries, child identity switching (replacing children who fell ill or died prior to departure with other infants to fulfill international contracts), and the aggressive extraction of surrenders from unwed mothers without informed consent.

• Institutional Recommendations: The TRC recommended official state apologies and legislative mechanisms to remedy falsified documentation, while mandating transparent archival access for adoptees.

3. Transition to State Oversight (NCRC)

Under current child welfare policies aligned with the Hague Convention on Protection of Children and Co-operation in Respect of Intercountry Adoption, the South Korean government established the National Center for the Rights of the Child (아동권리보장원 - NCRC). The NCRC is legally tasked with centralizing historically fragmented agency archives, managing birth family search registries, and removing sovereign recordkeeping authority from the Big Four's private control.

4. Historical Paradigm Shift & Modern Context

Evolution of South Korea's Adoption System: What began as an emergency response to post-war devastation and mixed-race war orphans in the 1950s evolved by the 1970s and 1980s into a state-sanctioned social safety valve for handling single motherhood, poverty, and urban displacement.

In recent decades, South Korea implemented significant reforms:

• Special Adoption Act Reforms (2011/2012): Enacted strict judicial oversight for adoptions, required court approval for all placements, and prioritized domestic placement over international adoption.

• Hague Convention Alignment: South Korea signed the Hague Convention on Protection of Children and Co-operation in Respect of Intercountry Adoption, leading toward full state control over child welfare and drastically reducing overseas adoptions.

• Truth & Reconciliation Commission Inquiries: In the 2020s, the South Korean government launched investigations into historical irregularities, falsified documentation, and coercion of single mothers within past intercountry adoption practices handled by these agencies.
