Just curious really. One day I'd like to move away.
My mum has a friend who left the UK nearly 20 years ago, has fallen on hard times and was considering coming back to the UK only to find she wouldn't qualify for any benefits at all or a pension. She's 50 now and wondering what'll happen when she reaches retirement age.
Not asking for advice on her behalf, but if I do go away I wouldn't want to end up in that position.
What's the usual practice - continue paying NI here or do you buy into the system of the country in which you're living?
Sorry if this is a stupid question.
