Korean Civil Documents Explained — Which One Do You Actually Need?

The 2008 reform: why 호적 no longer exists

Korea's old family register system (호적) was organized under a family head (호주) and abolished in January 2008 as part of a gender equality reform. All Korean civil records now use the individual-based Family Relations Registration System (가족관계등록제도). Documents are no longer issued under the 호주 — each person has their own individual record. If a foreign authority asks for a '호적등본,' the current equivalent is the 가족관계증명서.

기본증명서 — Basic Certificate

The 기본증명서 records fundamental personal information about a single individual: birth registration, name, registration number, any changes to legal capacity, and death registration. It is the closest equivalent to a birth certificate in international contexts.

• Contains: full name, resident registration number, date of birth, place of birth registration, name changes, death (if applicable)
• Issued by: any Korean municipal office (주민센터, 구청) or Government24 online
• International use: required by USCIS, German Standesamt, French état civil, Japanese municipal offices, and most immigration authorities when they ask for a 'birth certificate' — specify 기본증명서
• Apostille: MOFA apostille + certified translation required for international use

가족관계증명서 — Family Relations Certificate

The 가족관계증명서 shows the subject individual and their direct family relationships in one document: parents, spouse, and children. It replaced the old 호적등본 as the primary document proving family structure.

• Contains: the subject person's information plus names and registration numbers of parents, spouse, and children
• Two versions: standard (일반) shows current family; detailed (상세) shows all historical family relations including deceased members
• Issued by: any Korean municipal office or Government24
• International use: required for family reunification visas, partner visa applications, civil registration of marriage abroad, and wherever a foreign authority needs to see family structure. Often requested alongside the 기본증명서
• Apostille: MOFA apostille + certified translation

혼인관계증명서 — Marriage Certificate

The 혼인관계증명서 shows a person's marriage history — current marriage, previous marriages, and divorces.

• Contains: marriage date, spouse information, divorce information (if applicable)
• Standard version shows current marriage only; detailed version shows full marriage history
• Issued by: any Korean municipal office or Government24
• International use: spousal/partner visas, civil registration of marriage in a foreign country, civil status proceedings, inheritance
• Apostille: MOFA apostille + certified translation
• Note: if there is no marriage on record, the document shows 'blank' — this can serve as a certificate of single status when requested by foreign authorities

범죄경력조회서 vs 범죄·수사경력 회보서 — Criminal Background Check

Two different documents are issued by the Korean National Police Agency for criminal history, and they cover different scopes:

• 범죄경력조회서 (Criminal Records Check): Records only final convictions — cases that resulted in a guilty verdict and sentencing. Does not include investigations or arrests that did not result in conviction.
• 범죄수사경력조회서 (Investigation Records Check): Records all investigations — including cases where charges were dropped, acquitted, or not prosecuted.
• 범죄·수사경력 회보서 (Combined Criminal & Investigation Records Report): The combined report covering both conviction records and investigation records. This is what most immigration authorities require — it is the most comprehensive and is issued specifically 'for foreign immigration and stay' purposes.
• Always request the combined 범죄·수사경력 회보서 for immigration use unless your specific authority has requested the conviction-only version
• Issued by: Korean National Police Agency via crims.police.go.kr, any police station in Korea, or overseas Korean consulates

Academic documents — 학위증명서 and 성적증명서

For overseas employment, credential recognition, and graduate school applications, two academic documents are commonly needed:

• 학위증명서 (Diploma Certificate / Degree Verification): Issued by the Korean university confirming the degree awarded, graduation date, and department. Apostilled by MOFA after the university certifies it.
• 성적증명서 (Academic Transcript / Official Grade Report): Issued by the Korean university registrar showing all courses and grades. Apostilled by MOFA after the university certifies it.
• Required by: WES, NARIC/Ecctis, Nuffic, German anabin, and professional licensing bodies (NMC, GMC, Engineers Australia, AHPRA, etc.)
• Processing time: 2–5 business days to obtain from the university, then MOFA apostille

법인등기부등본 — Corporate Registration Certificate

For businesses and corporate matters involving Korean companies operating or transacting internationally:

• Contains: company name, registration number, registered address, directors, capital, company type, and all registration history
• Issued by: Supreme Court Registry (대법원 인터넷등기소, iros.go.kr) or any registry office
• International use: opening overseas corporate bank accounts, registering a foreign branch, signing international contracts, overseas investment filings
• Apostille: MOFA apostille + certified translation into the target language
