My spouse and I are making out seperate will that are identical in content.we are leaving everything to each other and do not want anything going to a "new spouse" in the event one of us dies and the other remarries.We think this will protect the surviving spouse and the adult children of surviving spouse. Also, we do not want our children to have any control over the surviving spouse to force a selling of the home to gain control of the dead parents share(the children's part?) However, if the surviving spouse wishes to sell the home, we do not want any proceeds going to the adult children until both parents are deceased. Is this possible and legal? What is this type will called? Do we need a lawyer? What does a lawyer cost?
