My document type is not listed. Can you still help?

Usually yes. Send the document and the instruction from the authority that requested it. The chain of certification depends on who issued the document and who will receive it, not on a fixed catalogue, so unusual documents are assessed individually before a plan and a fee are proposed.

Do you handle electronic documents and e-signatures?

Where the receiving authority accepts them, yes. Thailand recognises electronic signatures under its electronic transactions legislation, but many foreign registries and embassies still require a wet-ink original with physical seals. The accepted format should be confirmed in writing before work begins.

What if the destination changes its requirements mid-process?

We re-check requirements close to the filing date for exactly that reason, and if they change we set out the revised steps and any additional cost before continuing. Documents already certified can often be reused in the new chain, which limits the impact.

Certified Translation & Consular Legalization — Thailand → Indonesia

Question

How do I make a Thai document valid in Indonesia?

Answer

Certified translation → signature certification by a Notarial Services Attorney → legalisation by the Department of Consular Affairs → certification at the embassy or consulate of Indonesia. Typically 10–20 working days depending on each authority's queue.

NYC Legal handles certified translation and the full legalisation chain: certified translation → notarisation → Department of Consular Affairs → embassy for documents moving from Thailand to Indonesia. Every translation is proofread before delivery. Ask about fees by phone, LINE or email.

Chain: Thailand → Indonesia

1. Certified translation
Translated into English or the official language of Indonesia, with the translator's certificate of accuracy.
2. Notarial Services Attorney

Thai documents for use in Indonesia — service overview

NYC Legal & Notary handles the complete workflow for using Thai documents abroad in relation to Indonesia (อินโดนีเซีย): certified translation with the translator's certificate of accuracy, signature certification by a Notarial Services Attorney registered with the Lawyers Council of Thailand under the Council's regulation on the registration of notarial services attorneys, legalisation filings with the Department of Consular Affairs of the Ministry of Foreign Affairs, and coordination with the relevant embassy or consulate. Documents on this route still require the full legalisation chain, because Indonesia is not a party to the 1961 Hague Convention, or because the Convention is not yet in force for Thailand (instrument of accession deposited on 30 June 2026; entry into force 28 February 2027). Our team works daily with civil-status records, academic credentials, litigation papers, corporate instruments and immigration files. You can send documents by post or courier, by email or LINE, or visit our office in the Asok–Sukhumvit area of Bangkok. Before any work starts we review the document set and confirm the applicable steps and an expected time frame. Fees depend on page count, language pair, terminology and the government charges in force at the time, so we quote per case rather than publishing fixed prices — contact +66 83-249-4999 · LINE @NYC168 · info@nyclegal.co.th.

Legalisation procedure between Thailand and Indonesia

The certification chain must be completed strictly in order. If a step is skipped or performed out of sequence, the receiving authority will usually reject the file and the process has to start again. The exact requirements vary by document type (birth certificate, marriage certificate, degree certificate, power of attorney and so on), by receiving authority, and by purpose — marriage registration, study, employment, a visa application, or company registration. The overall time frame is typically 10–20 working days, depending on government queues and on whether the originals are complete; those queues are outside our control. We recommend confirming the current requirements directly with the authority that will receive the document, as internal rules are revised from time to time.

Scope of work and indicative time frames

The table below summarises the certification route and an indicative time frame for the documents we are asked about most often, so that you can plan ahead. It lists steps and lead times only. Costs are made up of translation work, signature certification, the Department of Consular Affairs legalisation fee and, where applicable, embassy fees set by the mission concerned; because those official rates can change, we do not publish fixed prices on the website. To receive a quotation for your own case, tell us the document type, the number of copies, the destination country and your deadline via +66 83-249-4999 · LINE @NYC168 · info@nyclegal.co.th.

Common reasons documents are rejected, and how to avoid them

The most frequent causes of rejection on the Thailand ↔ Indonesia route are: (1) the spelling of names in the translation does not match the passport, especially when several documents for the same person are spelled differently; (2) the certifying lawyer is not currently registered as a Notarial Services Attorney; (3) the civil-status document is older than the receiving authority allows — single-status certificates and police clearance certificates are commonly limited to 3–6 months; (4) the steps were taken out of order, for example presenting the file to an embassy before MFA legalisation; (5) omissions in the translation or legal terms rendered out of context. To prevent these, use the passport spelling consistently across every document, check the age of each original before starting, and confirm the sequence with the receiving authority. We proofread every translation before delivery; final acceptance nevertheless remains at the discretion of the receiving authority.

Document types we handle

We handle the document types most commonly required when using Thai documents abroad: civil-status records (birth, marriage, divorce and death certificates), academic documents (degree certificates, transcripts, diplomas), corporate documents (powers of attorney, company affidavits, board minutes), legal documents (court orders, wills, contracts), medical documents (medical certificates, vaccination records) and financial documents (tax certificates, bank statements). For specialised material outside the standard list — patents, foreign tax filings and similar — our team assesses the appropriate certification route case by case. Each document type also has its own detailed page on this site with step-by-step guidance.

Who this service is for (Indonesia)

This service suits: (1) Thai nationals who plan to study, work, marry or relocate to Indonesia; (2) parents enrolling children in schools or universities in Indonesia; (3) investors and businesses running cross-border transactions; (4) law firms that need a Bangkok back office for international certification work; (5) HR teams employing nationals of Indonesia; and (6) binational couples registering a marriage across jurisdictions. Our team works in Thai and English and coordinates with translators for other language pairs.

Frequently asked questions

How long does the whole process take for Indonesia?

Typically 10–20 working days, covering translation, signature certification, legalisation at the Department of Consular Affairs and the queue at the embassy or consulate of Indonesia, each of which sets its own submission and collection schedule.

How much does it cost?

Costs comprise translation, signature certification, the Department of Consular Affairs legalisation fee and any embassy fee, and vary with page count, language pair and the official rates in force at the time, so we do not publish fixed prices. Ask for a quotation for your case at +66 83-249-4999 · LINE @NYC168 · info@nyclegal.co.th.

Do you need originals or are copies enough?

Originals are normally required, or copies certified as true copies by the issuing authority. Requirements depend on the receiving authority, and we check this before work begins.

What if I am outside Bangkok or outside Thailand?

Send documents by post or courier, or appoint a representative to deliver them. We process the file in Bangkok and return it domestically or internationally.

Do you guarantee that the document will be accepted?

Final acceptance is at the discretion of the receiving authority, so we do not guarantee an outcome. We do check that the set is complete, proofread every translation before delivery, and tell you in advance the requirements we are aware of.

Do I have to attend your office?

Most matters can be handled online via LINE or email, sending scans first and originals afterwards. Attendance is required only where the law or the authority requires the signatory to appear before the Notarial Services Attorney. Our office is in the Asok–Sukhumvit area of Bangkok, by appointment.

Does an Apostille always replace embassy legalisation?

Not on this route. Indonesia is not a party to the 1961 Hague Convention, or the Convention is not yet in force for Thailand (accession deposited 30 June 2026; entry into force 28 February 2027), so documents still require Department of Consular Affairs legalisation and embassy or consular certification.

Can you arrange embassy appointments?

Yes. We coordinate appointments with the embassy or consulate of Indonesia in Thailand and prepare the forms and supporting documents. Appointment slots and fees are set by each mission.
