You will need full cover initially. Health cover is a legal requirement in France, although I don't think they police it, but you could encounter significant issues, both financial and legal, if either of you encounter a significant health issue. The EHIC isn't supposed to apply to residents. The alternative might be to take trips back to the UK for your health care?To be honest, I am not sure what I need, I will be moving from the UK to France, am I entitled to anything! or do I need full cover, I do have the European EHIC card.
I am 55 and my wife is 52, both in good health.
Another question, is the healthcare insurance a legality in France or can I just not have it al all.
