1. I regret to say that your children have no right or entitlement to any of the royalties from your ex husband's book. In law those royalties belong to him alone and only him. There is no basis in law for his children suddenly acquiring rights to any of his property, such as his stream of royalties. If you wish, personally, to get a share of his assets or income, then you will have to seek that as part of a divorce or separation proceedings. Apart from this method, there is nothing in law which forces a living person to share their property with anyone even their children. Different considerations apply on death.
