DD15 doesn’t like her name and wants to change it. She’s been saying this for years and most people already know her by her ‘preferred’ name. We support her in this. What’s the best way to go about this legally as I’m a bit confused about the options of an enrolled or unenrolled deed poll and whether to do it as parents before she’s 16 or let her do it herself when she’s 16-17 (but before 18)?
