Please could some one help me.  My husband and I are thinking of buying a home in France.  He has 6 grown children from previous relationships and 8 grandchildren.  He has had no contact with them for years and they do not get long at all.  He wants me to inherit the house.  If we purchased it just in my name, would the children have any claim?  I am I correct in assuming that if we bought it together, they would automatically inherit?  I know that they would fight every step of the way should anything happened to their father to have a share in the house. Any advice?
