- Where mistakes are most often made
- The document is translated before the apostille, or the translation is certified in the wrong place
- How long it takes
- From a few days to several months, depending on the country and the document
02 / In plain words
What Legalization chain means
The legalisation chain is the sequence of steps after which a document issued in one country is recognised in another. Put simply: your certificate on its own means nothing abroad until it has gone through the established confirmation procedure.
There are two routes. If both countries are parties to the Hague Convention, an apostille is enough — a special stamp of the competent authority. If at least one of them is not, consular legalisation applies: the document is certified in turn by several authorities and at the consulate of the destination country. The second route is longer and more expensive.
The main difficulty is the strict order of steps. First the document, with a notarised copy if needed, then the apostille or legalisation, and only then a translation certified under the rules of the receiving country. Swapping the steps is a typical and costly mistake: most often the whole chain has to be started again.
A case from practice
A client had the documents translated at home and the apostille added afterwards — the receiving side did not accept the set. The chain had to be gone through again, losing several weeks and incurring repeat costs. Here the order of steps matters more than speed.
When legalisation is needed
- Applying for citizenship or residence
- Registering a marriage abroad
- Recognition of a diploma
- Estate administration
- Company registration
- Court and notarial proceedings

06 / Expert advice

How to prepare in advance
Start with the requirements of the particular authority where the documents are to be filed: what form of document is needed, in what order to certify it, and where exactly the translation must be done. Then build a timeline that takes validity periods into account — some certificates are valid for a limited time, and starting too early is as harmful as starting late.
What we do for you. We draw up a document map for the specific programme: what exactly is needed, in what form, in what order to certify it and where to translate it. The client follows a ready-made route rather than finding out the requirements by trial and error.

07 / Questions
Frequently asked questions
The sequence of steps after which a document from one country is recognised in another: certification, an apostille or consular legalisation, translation.
An apostille if both countries are parties to the Hague Convention. If at least one is not, consular legalisation is needed — it takes longer.
After the apostille has been added. If you translate earlier, the stamp on the original will be left untranslated and the set will not be accepted.
As a rule, under the rules of the receiving country — often by a local sworn translator. This is confirmed before translating.
From a few days to several months. It depends on the country, the type of document and the chosen legalisation route.
Some do, especially certificates. That is why the collection timeline is built so that they do not expire before filing.
