The Chartered Institute of Legal Executives (CILEx) is an Approved Regulator under the Legal Services Act 2007 for authorising Chartered Legal Executives to administer oaths.
If you are a Chartered Legal Executive you can call yourself a Commissioner for Oaths. Read our Administration of Oaths guide. This sets out the procedure for administering oaths.
The guide confirms that oaths may only be administered by Chartered Legal Executives who hold a current practice certificate. Those registered in the retired Chartered Legal Executive grade of CILEx membership are unable to administer oaths. The guide also explains the circumstances in which you should not administer oaths.
