A dying man, knowing his wife was pregnant, left a will that divided his estate between his child and his wife, giving 1/3 to the wife if she gave birth to a son, and 2/3 to the wife if she birthed a daughter. As it turned out, she birthed fraternal twins: a son and a daughter. You are executor of the will. Wishing to adhere as closely as possible to the man's wishes, how will you divide the estate among the three heirs?
If you desire more guidance than what has been provided, the situation is clear: there is no more guidance than what has been provided. You are the law.
