Apostille a UK birth certificate for Argentina

A child's family-residence application in Argentina may depend on a birth certificate showing who their parents are. For a UK-registered birth, the usual paper route is a full official certified copy, an FCDO apostille attached to that copy, then a Spanish sworn translation of the certificate and apostille if the Argentine receiving office requires it. Allow several weeks for ordering, post and translation. The FCDO paper apostille alone costs about £45 per document in September 2026, with postage and translation extra.

Find out whose birth needs proving

Dirección Nacional de Migraciones (DNM), Argentina's national immigration directorate, sets the evidence list for each residence category. A child joining a parent may need their own certificate to show parentage; an adult applying on a work or passive-income basis may have a different list. The certificate establishes facts about birth and family relationship, while the residence decision depends on the application as a whole. The family-reunification route and UK-citizen visa overview explain the wider residence context.

Before ordering, establish which person's record DNM wants, whether both parents must appear and how recently the copy must have been issued. The registration date of an old birth and the issue date of a new certified copy are different. Some offices impose a document-age rule for a particular procedure, but there is no universal six-month rule for every Argentine application. The receiving office also determines its Spanish translation and translator-signature requirements.

Order a full record from the right country

The full certificate is an official certified copy of the register entry, showing the parents' particulars that a short version omits. The place of registration determines the issuing authority, even if the person named on the record is British.

For an England-and-Wales GRO order, the standard certificate cost about £12.50 in September 2026; priority service and international delivery cost more. The ordering service asks for the name at birth, date and place of birth and, where available, parents' details. Its search service can help if the register reference is missing. Check names against passports and marriage or name-change records before sending the copy for legalisation. A scan, hospital keepsake or solicitor-stamped photocopy is a different document from an official register-office certificate.

Have the FCDO apostille the official copy

The UK and Argentina are parties to the Hague Apostille Convention. The apostille authenticates the origin of a UK public document, not every statement recorded on it. For a paper file, apply through GOV.UK's Get your document legalised service, select the paper route and send the official issued certificate to the address given with your application reference. The paper apostille is attached to the certificate and should stay with it. A UK record carrying the appropriate apostille normally needs no second legalisation at an Argentine consulate.

At September 2026 prices the paper apostille is about £45, plus outbound and return postage; the checkout price controls. Tracked delivery is helpful where offered. Applying from Argentina involves two international delivery legs unless a trusted person in the UK handles dispatch. The British Embassy in Buenos Aires and Argentine notaries cannot issue an FCDO apostille. An e-Apostille is an option only if the FCDO offers it for the record and the Argentine receiving office accepts an electronic set. A paper certificate and attached paper apostille are the straightforward pairing for a paper submission.

Translate the whole set for the receiving office

Once the apostille is attached, a registered Argentine *traductor público* (sworn translator) can translate both it and the certificate. Ask the office receiving the file whether the translator's signature also needs *legalización*, authentication by the relevant provincial professional college. In Buenos Aires city that college is the Colegio de Traductores Públicos de la Ciudad de Buenos Aires (CTPCBA). A quote covering both documents and any college legalisation gives a more realistic timetable before a filing appointment is booked. The sworn-translation guide explains this stage.

For a child born in Manchester joining a parent in Buenos Aires, a full GRO copy at about £12.50 and a paper apostille at about £45 make a UK subtotal of approximately £57.50 before postage (September 2026). A CTPCBA-registered translator would then quote for the child's certificate and attached apostille. At the September 2026 reference rate of roughly ARS 1,545 per US$, a hypothetical ARS 30,900 quote would be about US$20; it is an illustration, not a published translator tariff. Residence fees and other family documents remain separate. The child's certificate identifies their parentage in a way that ordering the parent's own certificate would not.

When the document takes a different route

A short certificate missing parents' details, an apostille on a photocopy, a detached apostille or a translation that omits the apostille can all send a file back for correction. A UK-made translation may also fall short of the Argentine office's local translator and signature rules. Keeping the original attached set together and retaining photos for your records makes the handover easier; photos do not replace the originals for a paper submission.

A UK marriage, divorce or police certificate has its own issuing authority and evidence requirements, though the apostille principle is similar; see the UK-document apostille guide. For a child born in Argentina, the starting point is the Argentine birth record and the British-child-born-in-Argentina guide. A birth registered in a third country follows that country's apostille process, with translation requirements set by the Argentine office receiving it. The deciding detail is where the birth was recorded, not which passport the family holds.
