In this country any gift to a person be it for a birthday, a holiday, graduation, or upon death is the personal and separate property of the person who receives it and is not community property at the time the gift is given unless the gift is actually intended to be community property.The only way your husband could acquire an interest in a gift to you upon your father's passing is if he actually intended to give him an interest in it, or once you receive it as separate property, you give him an interest in it intentionally or impliedly by placing his name on it.If you receive this bank account upon your father's death and do not want him to have an interest in it, set up a bank account in your name as your separate property.Good luck.
