Many thanks for your clear and comprehensive reply.
I have a supplementary question:
If I am to obtain the Royal Court of Jersey's consent to the procedure you and my notaire have outlined as required under French law I will need to provide the Royal Court with an explanation of what it is granting its consent to.
Can you explain the role of the notaire's clerk and what if any duties he will be required to perform? Is he in fact acting as a form of substitute guardian/curateur in my place as I am deemed to be conflicted and will his role be a continuing role or a "one off" simply to effect the transfer the life interest in my father's half of the French property to my mother?
