going abroad on Thursday with my dc and mum. Mum and I are not citizens of the UK but dc is. All three of us live here. I am married to dc’s father but have kept my surname (mainly due to difficulties in covid to change name as required a face to face appointment but no face to face appointments available so renewed my passport under maiden name. Would have otherwise change name just for ease of travel!)
will this cause any problems? I will have his birth certificate with me that states my place of birth but DH remembers travelling with his mum (also not uk citizen at the time) and needing a notarised letter from his dad. Do I need anything else?
