The surname on all my credentials (WAEC, degree, NIN, international passport etc) is Tunji, but I don’t want my children to bear Tunji but Olatunji. My children now have Olatunji as there surname on there birth certificates and NIN. I have done affidavit in court to claim that I am the same person having surname as Tunji and Olatunji. So my questions are, is this acceptable legally and will there be any problem at the airport when traveling abroad with the children. Or any future implications for me and the children.
