Ex hasn’t seen 2 of 3 children for 3 years, which was one session and two sessions (contact centre) previously to that it was one year with no contact and previously to that it was 2 years no contact.
One child hasn’t seen him at all since 2012. Contact was short lived for around 4-5 months.
He sends a card (well his gf does) once a year.
Children all want to change their surname to my remarried name, or at least double barrel with their current one.
Can I do this by deed-poll?
