When we saw the solicitor, he gave us 3 options
1. Get a letter from 3 members of the community (doctor, vicar, council member etc) who had known Daniel before his name change. You can use the letter to get the name changed at school, doctors, hospitals, etc.
2. Change name by deed poll - you fill in an application form and get back a certificate you can use instead of the birth certificate. This way you can change your name on a passport, driving license etc
3. Legal adoption - 9 years ago it meant us BOTH adopting Daniel, going through all the checks a 'normal' adoption would have to go through. I didn't want to do it on principal - why should I have to adopt my own son. If we had gone through the adoption, it would mean OH would have legal responsibility for Daniel if I died, OH would be responsible for maintenance if we ever seperated and we wouldn't have to deal with the CSA re Daniels sperm donor.
