In plain words

A certified copy is a copy of a document with an official mark confirming that it matches the original. It is usually certified by a notary; in some cases this can be done by the authority that issued the document or by a consulate. The idea is simple: to file documents without parting with the original.

This is especially important when the same document is needed in several procedures at once, or when the original cannot be replaced quickly. Passports, birth certificates, diplomas and corporate documents are more often filed as certified copies, while the original stays with you.

There are two practical rules. First: the copy must be complete — all pages, including blank and reverse sides, and all stamps and marks. A partial copy is invalid. Second: not all authorities accept copies; some procedures require originals or copies certified in a particular way. This is found out before paying the notary.

When a certified copy is needed

Filing documents with several authorities
Applications for residence or citizenship
Opening a bank account
Company registration
Drawing up a power of attorney
Keeping a back-up set

What this means for a BRIDGES client

We work out in advance how many certified copies will be needed and of which documents, so that the client does everything in one visit. The originals stay with the client — we try not to send them between authorities unless absolutely necessary.

Frequently asked questions

01 /What is a certified copy?

A copy of a document with official confirmation that it matches the original — usually from a notary, sometimes from the issuing authority or a consulate.

02 /Is it accepted everywhere?

No. Some procedures require originals or copies certified in a particular way. This is confirmed in advance.

03 /Do all pages need to be copied?

Yes. The copy must be complete: all pages, reverse sides, stamps and marks. A partial copy is invalid.

04 /Where does the apostille go?

It depends on the receiving side’s requirements: sometimes on the original, sometimes on the notarised copy. This is found out before filing.

05 /Can a copy of a copy be certified?

As a rule, no. The original document is presented for certification.

06 /Does certification expire?

The copy itself usually does not, but some authorities require the certification to have been made recently. This is confirmed for the particular procedure.
