Yes, she would but only after a qualifying period, I think 6 months. She would automatically get NHS services if she declares she is now a resident as she is a British citizen. If the children came with her, she would also get child benefits. Of course, if she does have that 100,000 stash away ( 84,123.49 at the current exchange rate) she would automatically be disqualified from benefits until she reaches a certain level. She wouldn't qualify for a UK pension as she has not contributed enough (35 yrs) and they don't have a married pension anymore, you have to qualify on your own right now. There is no attraction to the UK, moneywise, to be honest, unless you have money already. As she can't live to the standard she wants already, going back to the UK is non-starter.Will the Abuser get any benefits if she hasn’t paid her taxes and NI here?
My parents lived in France for about 10 yrs and returned when they became too infirm to live on their own there. But they had lived in the UK up to their retirement age. The health service and benefits in France were much better but it was not practical as my 2 sisters lived in the UK, my other sister in Australia and I am in the US.
