When do you need a sworn translation?

Every operative document in an Indonesian property transaction is in Bahasa Indonesia, and the Indonesian version governs. A sworn translation is how you know what you are signing.

What a sworn translation is

A translation produced by a penerjemah tersumpah — a sworn translator formally appointed and authorised to produce translations that carry legal weight.

It is not the same as a good translation. A fluent bilingual friend, an agent, or a translation app can tell you what a document says. None of those produce a document that an Indonesian authority, a court, an embassy or a notary will accept as an authoritative rendering.

The distinction matters at exactly the moments it is expensive to discover.

When you need one

Property documents you are signing. A lease deed, a sale and purchase deed, a power of attorney. You are committing to a contract in a language you probably do not read, and the Indonesian version is the one that governs regardless of any English summary.

Foreign documents submitted to Indonesian authorities. Birth certificates, marriage certificates, police clearances, academic qualifications, company documents — for visa applications, company formation, marriage registration, or land office matters.

Indonesian documents submitted abroad. Certificates, deeds, company documents, court records.

Anything going to court.

The chain for foreign documents

A foreign document usually needs more than translation before an Indonesian authority will accept it.

The sequence is typically: the document is notarised or certified in its country of origin, then legalised — either by apostille where both countries are parties to the Hague Apostille Convention, which now includes Indonesia, or through consular legalisation where they are not — and then translated by a sworn translator.

Order matters. Translating first and legalising afterwards frequently means doing it twice. Ask the receiving authority what sequence they require before you start, because practice varies and a rejected document costs weeks.

What it costs and how long it takes

Modest against what it protects. Pricing is generally per page or per word, with certificates and short documents inexpensive and long contracts more.

A few days for ordinary documents, longer for volume or specialist content.

Against a property transaction where the document commits you to hundreds of thousands of dollars, this is one of the cheapest items in the process and one of the most commonly skipped.

Reading the translation properly

Read the Indonesian version's numbers yourself, even if you cannot read the text. Dates, areas, sums, percentages and terms are legible in any language. A mismatch between the English translation and the Indonesian figures is one of the more common problems in this market, and you can catch it without speaking a word of Indonesian.

Have your notary walk you through the Indonesian text clause by clause. That is part of the job, and a notary who will not do it is the wrong notary.

Look specifically for the clauses that carry the value: the term, whether the extension is *jaminan* or *prioritas*, whether the deed binds heirs and successors, and whether assignment and sublease are permitted.

The mistake to avoid

Accepting an agent's English summary as equivalent to the document.

It is not. It is a description of a document written by someone paid on the transaction completing. Where the summary and the Indonesian text differ, the Indonesian text wins and your understanding of what you agreed is irrelevant.

The sworn translation costs a few hundred dollars. Not having one has cost people considerably more.

Keeping them

File the sworn translation alongside the original deed, somewhere reachable from another country.

Years later, when you sell, when an heir needs to act, or when a dispute arises, having the authoritative translation to hand is the difference between a straightforward process and an expensive one.
