TMZ:  Alan Thicke's widow says his sons are treating her unfairly and believes they might be recklessly spending his money while holding out on her inheritance … according to new legal docs. Tanya Thicke claims Alan's sons — Robin and Brennan, who are co-trustees of their late father's estate — are not only keeping her in the dark about how they are managing his trust ... but are ganging up on her and possibly robbing her from what she's owed.
