Are there any stamp‑based official seals used in notarised translations of marriage certificates in UK (or another country)?

Yes, stamp-based official seals are commonly used in notarised translations of marriage certificates, both in the UK and in many other countries. These seals serve as a mark of authenticity and legal recognition for the translation.

United Kingdom
In the UK, when a marriage certificate translation needs to be notarised—for example, for use abroad or for official immigration purposes—it typically involves the following steps:

Certified Translation: The document is first translated by a qualified translator or translation company. The translator then signs a statement of accuracy.

Notarisation: A Notary Public verifies the identity of the translator and certifies the declaration with a notarial stamp or seal. This stamp may include the notary’s name, credentials, and registration number.

Legalisation (Optional): For use in some countries, the notarised translation may also require an Apostille stamp from the UK Foreign, Commonwealth & Development Office (FCDO).

The notarial stamp or seal used in this process is usually a rubber or embossed stamp applied to the document, signifying its notarised status.

Other Countries
In countries like Germany, Spain, or Italy, similar processes apply, often involving:

A sworn translator or certified translation service,

An official stamp or seal on both the original and translated documents,

Notarisation by a local notary public, and sometimes,

Legalisation through an Apostille.

Summary

While notarised translations aren’t always required for domestic use in the UK, they are often necessary for international legal purposes. A stamp-based official seal—whether from a translator, notary, or government authority—is a key feature of a notarised marriage certificate translation, providing legal credibility and ensuring the document is accepted by authorities in the relevant jurisdiction.
