Child & Mum in France, Dad in England

[LadyandGent]

My friend's ex wife lives in France. Their ds is 12 and lives with the Mum (Mum is French and ds is French I think). My friend lives here in England and is English. He doesn't have any formal access arrangements, but generally, the ds comes over for a couple of weeks over the holidays. How is this now going to work out for him post Brexit?

in practice an English speaking parents would rarely if ever be asked to prove entitlement.

This absolutely is not true.

TMs views on foreigners are irrelevant to the Brexit vote.
I have no way of knowing which way she voted, nor do I care.

As an immigrant who faced her progressively racist and xenophobic policies
eg Windrush
I know that the UK has the most hostile visa regime in the world.

Willit
EU citizens are currently protected by EU membership.
US citizens are protected by trade deals
Commonwealth citizens thought they were protected - but Windrush has proved them wrong

trust NOTHING with the UKBA

I didn't realise that about healthcare - my dual national but non resident (at the time) DC definitely had free NHS treatment when we were visiting family in the UK without an EHIC, but that may have changed.
It changed in 2015. Non-resident citizens now have to pay (although EU residents are obviously covered by EHIC for the moment).

Emergency treatment is always free. This is not true, we had to pay for emergency hospital treatment.

The child will in any case be insured in the French system and the mother should be able to claim back any costs incurred. She could at the moment, but after Brexit surely it will depend on any deal reached.

This is not insurmountable, it just means health insurance will be needed.
