Greetings everyone. Sorry for this a long explanation.聽
I have had a carte de sejour for two years. Originally I got it so I could be in both the civil AND the church wedding of my child, which were six months apart.
I felt lucky that I got the carte de sejour because the next year I came to France for three months and due to Covid I have been here 16 months!

I did not understand at first that getting a carte de sejour meant that I am now a resident of France.
I do not mind paying French taxes,
but...

and here is the problem...

I just found out that as a resident聽 my estate will be subject to French law when I die, and all the estate planning I did in the United States is worthless here and my child鈥檚 inheritance will be half of what it would be in the USA.
So I am in a bit of a shock and thinking I must give up on being in France, except for short holidays.

I have been trying to find a Notaire to help me and so far, no help. I have had only one Notaire write back, and he said that for 鈧�6000 he would research my situation.(!)

My questions are:
*Since I have not been able to find information I am thinking I must at least temporarily give up my residency to protect my daughter鈥檚 inheritance.
Can I 鈥渄elete鈥� my residency status by staying less than 183 days this year?
But
*If then I decide later that I really do want to keep my carte de sejour, must I start over from the beginning...that is, go to a French embassy in the United States to apply? Or can I apply at my prefecture for a new carte de sejour. My child is married to a French citizen and lives in France.

I know these are probably questions for a notaire, but I am clueless about finding a good one.
Has anyone had this issue with inheritance laws?
Thank you.
