The house belongs to parents' property, and what is written now belongs to witness and the like, which is a basis. In fact, a hundred years after your parents, according to the inheritance law, you, your brother and their related heirs have the right to inherit your parents' property. Maybe many years later, your parents' will is the only basis. I advise your parents to be filial when they are born, so it is good for you to divide the property. There is no winner in the future property competition, and the result is the loss of family ties.
