In UK law, a Commissioner for Oaths is a person appointed by the Lord Chancellor with power to administer oaths or take affidavits. Our solicitors in Ilford, London administer oaths and take affidavits.

This is an appointment automatically granted to certain legal professionals who are in practice on their respective profession or to some others because of their position or role in the legal system.

The exact description of the Commissioner for Oaths in Oxford English is:

“A solicitor authorized to administer an oath to a person making an affidavit.”
