This is automatically added to your deed poll generated by freedeedpoll.org.uk if you tick the “First name changed?” box. Mr Justice Vaisey set precedent for England and Wales in the case specified by stating that he did not believe it was possible for a person’s Christian name to change.

For this reason, many deeds poll (and especially those for which the first name is changed, particularly if they want to be enrolled) carry the message you describe, which is basically saying “I know that legal precedent has been set to say this is not possible, but I disagree and I’ve changed my name anyway.” The joys of a Common Law system!
