1. I regret to say that you only have rights in relation to your Dad's estate. This comprises only the assets he owned. If a property was bought in the name of the woman with whom your father lived, then that is hers. As son of her former partner, you have no rights in relation to her assets. So I regret to say that even though your father might or did contribute to the buying of this assets in the name of this woman he was with, you have no rights in relation to it. You can only claim a share in your father's own assets at the date of death.
