I am considering adding an additional middle name to each of my children's names - my maiden name. As they are aged 6 and 2 I have to do this by deed poll. It occurred to me that if they need to prove their identity in the future it may be a nuisance for them to have to produce both birth certificate and deed poll, but then if it is only adding a name and not changing the existing names perhaps a birth certificate on its own would be OK.
Can anyone help?
