Answer: Major part of share should be given to henry and the rest should be given to other children.
Explanation: In the given case, Henry is going to get divorced next year hence if he gets to have his part of share today, he have to split the half with his wife after the divorce.
Thus, Anna and John should gift the major part to Henry as he is suffering from financial crisis and leave the remaining portion for other two kids. Also the division should be done only after the divorce of Henry and as a gift so that he did not need to pay the tax.
