Commissioner for oaths — explained for Turkish readers
A person authorised in England and Wales to administer oaths and take affidavits and statutory declarations. Every practising solicitor holds this power.
A commissioner for oaths is someone with legal authority to administer an oath or affirmation and to witness a sworn document such as an affidavit or a statutory declaration. Under the Solicitors Act 1974 every solicitor with a practising certificate has this authority automatically; notaries public also hold it. The commissioner charges a small fixed fee.
Türkiye has no separate office of this kind. The closest function is the noter's certification of a signature or a declaration made in person, which is why a Turkish translation of “commissioner for oaths” usually reads as a descriptive phrase rather than a single word. The commissioner does not read or check the content of what you swear; responsibility for the truth of the statement stays with you.
If a document sworn in England is going to a Turkish court or office, it will normally need an apostille and a translation, and the person who took the oath is named in it. See notaries and solicitors.
