Overview

• The UK Deed Poll Office assesses baby names on a case-by-case basis to ensure they do not cause harm, ridicule, or confusion for children.
• Names may be rejected if they include offensive language, symbols, or numbers, are overly long, or imply misleading titles like 'King' or 'Princess'.
• High-profile rejections include 'Cyanide', 'Martian', 'King', and 'Princess', with courts blocking 'Cyanide' but allowing 'Preacher' in a notable twin naming case.
• Parents must select an approved name before birth certificates or passports are issued, with rejected names subject to legal challenges post-registration.
• Similar naming restrictions exist globally, with countries like New Zealand and Germany banning names such as 'Lucifer', '4Real', and 'Adolf Hitler'.
