Thank you all again for your input. Looking into "procuration", I think this is more to do with appointing a proxy who can carry out certain things on your behalf where you may not be able to attend in person and is subtly different from what I was looking for, which is the ability to actually take control of someone's affairs, both personal and financial, and make decisions on their behalf should they lose capacity, which I think is what the "mandat de protection future" is for. There is a suspicion that my father may be displaying early signs of dementia so I'm keen that safeguards are put in place before either of them lose the capacity to consent to this. I'm also hopeful that if we could do this in time, it would avoid the necessity of having to get guardianship set up, which I understand can be complex and expensive. To be honest, it has now come to the point where they really need to be selling up and come home - my mother has developed serious health problems and nearly died just before Christmas but until they take this on board, I'm just trying to see what we can do to protect them in the meantime, albeit from a distance. It's an extremely worrying time for the rest of the family, as I'm sure you'll understand so I'm very grateful for the advice you have all provided so far. Thanks McNumpty
