I changed his first and middle name as he already has my surname . You can change any name you want , you just have to send the original deed poll plus orginal birth certificate to the passport office , GP Surgery ,Schools etc when you inform them of the name changes . You don't need to use a paid service but for me it was easier plus it was cheap enough . I was lucky to have a solicitor friend as my witness . Do I need to get a solicitor to witness me sign my Deed Poll? A: If you are British and live in the United Kingdom, your witness can be anyone so long as they are at least 18 years of age; know you and are independent of you i.e. not a relative or partner or someone living at the same address. A suitable witness would be, for example, a friend, neighbour or work colleague. If you are British and living overseas, you will need to have the signing of your Deed Poll witnessed by a lawyer or a notary public. If you are not British and live in the United Kingdom, you should check with your Embassy (the passport section in consular services) to ask if your Deed Poll needs to be witnessed by either a UK solicitor or a notary public. Please note, if your Deed Poll needs to be legalised with an Apostille, it will need to be witnessed by a UK solicitor or a notary public.
