Ask the Adoptee Rights Assistant
Start by identifying the records and rules that apply
Aimak or Ulaanbaatar district, ministry file, Immigration Agency order, civil registration office, institution, adoption year and Mongolian name spellings determine the record map. Do not invent a court file where the final decision was administrative.
If the person came to the UK, obtain the UK receiving or adoption agency file, court papers and immigration and nationality records in parallel. Confirm whether a later UK adoption order was made. UK records do not replace the records held in Mongolia.
Check the current procedure before applyingThis guide explains the likely process, but forms, contact details, eligibility and access rules can change. Check the linked source before sending identity documents or paying a fee.
Choose the situation that describes you
Adopted in Mongolia
What applies: Confirm that the legal adoption or other arrangement was made in Mongolia, and identify the date, place, court or authority and institution.
How to look for records: Identify the Ministry of Family, Labour and Social Protection, the Immigration Agency that made the final intercountry adoption decision, the State and Civil Registration authority and any orphanage, local governor or child and family agency. Request the adoption decision, adoption authority or welfare dossier, original civil registration, consent and social material, and institution record separately. A later birth certificate or adoption certificate is not the whole file.
How to look for family: No verified public nationwide adult origins application was found. Ask the ministry and Immigration Agency to identify the adoption and matching files, then ask the civil registration authority about the original and amended entries. Mongolia’s intercountry process is administrative rather than a standard civil court adoption process.
Important: Do not assume a civil court file: the Immigration Agency makes the final intercountry adoption decision.
Born in Mongolia and brought to the UK
What applies: Establish whether the legal adoption was made overseas, in the UK, or in both places; keep the two countries’ records processs open until that is known.
How to look for records: If the person came to the UK, obtain the UK receiving or adoption agency file, court papers and immigration and nationality records in parallel. Confirm whether a later UK adoption order was made. UK records do not replace the records held in Mongolia. Identify the Ministry of Family, Labour and Social Protection, the Immigration Agency that made the final intercountry adoption decision, the State and Civil Registration authority and any orphanage, local governor or child and family agency. Request the adoption decision, adoption authority or welfare dossier, original civil registration, consent and social material, and institution record separately. A later birth certificate or adoption certificate is not the whole file.

Important: A UK adoption or registration record does not automatically disclose or replace the overseas birth, court, welfare or institution file. Do not assume a civil court file: the Immigration Agency makes the final intercountry adoption decision.
A birth parent was from Mongolia
What applies: Start with the records of the country where the person was born and adopted. A parent being from Mongolia does not by itself mean that Mongolia holds the adoption file.
How to look for records: Obtain the adoptee’s own birth and adoption records first. If they confirm the parent’s identity or a locality in Mongolia, use the relevant civil registration, archive and family history sources there.
How to look for family: Use verified full names, spelling variants, dates, locality and institution with the relevant civil registry, adoption authority, court or decision maker and archives in Mongolia. Keep official records work separate from supported and consent sensitive family contact. DNA may provide a parallel family finding lead, but database representation for Mongolia may be uneven. Check current provider availability and any rules affecting sample collection or export. A match is a lead, not proof; corroborate it with shared matches and records, consider privacy and unexpected results, and obtain consent before testing another person.
Important: Do not assume nationality proves birth, citizenship or registration in Mongolia. Confirm full names, spelling variants, dates and an actual locality before making overseas enquiries.
Records and family finding
Start with records
Identify the Ministry of Family, Labour and Social Protection, the Immigration Agency that made the final intercountry adoption decision, the State and Civil Registration authority and any orphanage, local governor or child and family agency. Request the adoption decision, adoption authority or welfare dossier, original civil registration, consent and social material, and institution record separately. A later birth certificate or adoption certificate is not the whole file.
Looking for family
No verified public nationwide adult origins application was found. Ask the ministry and Immigration Agency to identify the adoption and matching files, then ask the civil registration authority about the original and amended entries. Mongolia’s intercountry process is administrative rather than a standard civil court adoption process.
DNA
DNA may provide a parallel family finding lead, but database representation for Mongolia may be uneven. Check current provider availability and any rules affecting sample collection or export. A match is a lead, not proof; corroborate it with shared matches and records, consider privacy and unexpected results, and obtain consent before testing another person.
Peer support
ICAV currently lists no Mongolia specific group. Its broader Asian adoptee groups and general search guidance may help; check eligibility, activity, language and privacy.
Practical next steps
If you have no namesUse the adoption certificate or order, travel papers and receiving country file to identify the authority, court or decision maker, civil registration locality and institution in Mongolia. Ask each identified holder for the underlying file and current adult access procedure.
If you have a name or placeUse verified full names, spelling variants, dates, locality and institution with the relevant civil registry, adoption authority, court or decision maker and archives in Mongolia. Keep official records work separate from supported and consent sensitive family contact.
If the search has stalledAsk each possible holder in writing whether the record survives, was transferred or is restricted, and what review or court process applies. Then consider archives, verified peer support and carefully corroborated DNA as separate procedures.
