I have a very complicated situation, which I know I'll have to seek advice on in the future and possibly take some calculated risks. My husband, son and I would like to buy a house with my mother and stepfather. My husband also has a child from a previous relationship. My stepfather has none and is like a father to us. We are wondering what would happen under french succession if my mother and I bought the house in our own names (it would be my own money). When my mother died (if before me), from what I understand 2/3 of her estate would go to my brother and I. She could freely dispose of another third. Would I be able to buy my brother out? (He would be agreeable to this) If I died first, and my portion was left to my son, would my husband have the right to remain in the house as his parent and guardian? Could I stipulate that my husband has the right to remain in the house until his death, even though it wasn't owned jointly? I know this is quite a challenging query, and we will not rush into anything as we intend to rent for a year or two before buying a property. I just want to see what other considerations, ideas get thrown up. We'd like to try and leave a whole house for my son and use other assets to balance inheritances.
