My spouse and I have a will drawn up by an attorney's office and notarized by his staff. It specifies that all I possess goes to my spouse upon my death. When my spouse dies my adult children get all he possesses. I'm a bit concerned that if my spouse remarries, his spouse would receive upon his death all he possesses as it states in the law as community property. How can I ensure MY children get their part as the house belongs to me and most everything I've saved or earned during my 37 year employment?
