I want to change my dds surname to my now married name.
Her dad left us when she was one and has never contacted her since (she is 6) nor does he pay maintenance or acknowledge her birthdays/Christmas. Likewise, his mother has never seen dd since the day he left. She doesn't remember them, and doesn't know any other parents than us.
I don't know fully where exp is, other than in the Middle East. I know where his mother is living and that is the only details I have.
I'm confused as to whether I can do it through deed poll, or if I need a court order. I believe the passport office (for example) can be funny about it without a court order, but I have read I could try through deed poll first.
I also wish to go to court for residency. Although ex doesn't see dd, the different names and no residence order has raised issues over holidays etc.
Could someone walk me through how I deal with the name change and the residency please.
Thanks!
