Paperwork

Apostille and legalization for Hong Kong and Taiwan documents

October 23, 2026 · ~7 min read

Relocations rarely collapse for dramatic reasons — they collapse over paper. The visa gets researched for months; the documents get discovered in the final fortnight. And Hong Kong and Taiwan sit on opposite sides of the 1961 Hague Apostille Convention: the same certificate, sent to the same country, takes one step from Hong Kong and a three-step chain from Taiwan. Same destination, different journeys.

This guide is educational — rules change, so verify with the official sources linked inside before you act.

Key takeaways

Hong Kong documents: one step — an apostille from the High Court, HK$125 per document.
Taiwan documents: three steps — notarization, authentication by the Bureau of Consular Affairs (BOCA), then legalization at the destination's representative office in Taiwan.
Police records run on a separate track: the CNCC in Hong Kong, the 良民證 in Taiwan.
Many destinations also require certified or sworn translation — check the accepted-translator list before paying anyone.

The Hong Kong path: one step

Hong Kong is covered by the 1961 Hague Apostille Convention, extended to the city via China. For use in another member country, a Hong Kong document needs a single certificate — an apostille — issued by the Registrar of the High Court. The Apostille Service Office sits at Room LG115, High Court Building, 38 Queensway, Hong Kong, and charges HK$125 per document; an e-Apostille service launched in 2025 lets you apply, pay, and receive the certificate electronically. The Judiciary's apostille page sets out the current procedure.

An apostille confirms a signature, seal, or stamp is genuine — nothing more. A destination can accept the certificate and still reject the document it covers.

The Taiwan path: three steps

Taiwan is not a party to the Apostille Convention, so its documents travel a longer chain, completed strictly in order:

Notarization. The document is notarized by a notary public or a district court.
Authentication. The document goes to the Bureau of Consular Affairs (BOCA) or a Ministry of Foreign Affairs branch office. BOCA's documentation pages list what to bring — original notarized documents, identification, and one notarized copy.
Legalization. Finally, the destination country's representative office in Taiwan legalizes the document — the step that makes it valid for that country. Check that office's requirements before you queue.

The chain is serial: a missing stamp invalidates everything after it. Work in order, checking each office's rules against BOCA's authentication guidance.

Police records: a separate track

Criminal-record certificates are their own documents with their own rules. Hong Kong issues the Certificate of No Criminal Conviction (CNCC) through the Hong Kong Police — consent-based, for immigration purposes; some receiving authorities want their own request letter first, so confirm before assuming. Taiwan issues the Police Criminal Record Certificate (良民證) through local police departments; Taiwanese overseas can apply through BOCA-affiliated channels. Neither system accepts the other's certificate — budget them separately.

Translations: the quiet fourth step

Many countries require documents translated into their official language by a certified or sworn translator — Portugal and Germany, for example, generally expect sworn translations from an accepted list. The rules belong to the destination, not the origin: a translator valid for one country may mean nothing to the next. Find the destination authority's list before commissioning anything. Heading to Portugal on the D7 or D8? Open that list first — see our Portugal guide.

Degree certificates and transcripts
Marriage and birth records
Police record — CNCC (Hong Kong) or 良民證 (Taiwan)
Proof of funds or income
Certified translations of the above, where required

Cost anchor: a Hong Kong apostille is HK$125 per document (Judiciary); Taiwan's chain charges at each stage — confirm amounts with BOCA and the destination's office.

Timing mistakes that force re-dos

Three patterns eat timelines. Ordering too early: police certificates are commonly accepted only within a few months of issue, so certifying one first and filing last can mean redoing both. Assuming no freshness rules: an apostille doesn't expire, but receiving authorities limit how old documents may be. Underestimating serial steps: the Taiwan chain runs one office at a time, and every authority adds a queue. Make the bundle fresh on submission day, not start day. Before any of it, make sure the door is right: start with how to choose your emigration route, or compare the lighter paperwork of digital nomad visas.
