This is a practical question, looking for existing Shu"Ts that cover this scenario:
- A child takes care of his old and dying father for a couple of years - he feeds him, pays for a nurse, housekeeper etc.
- The father does not talk and neither of them is explicitly mentioning his monetary intentions.
- One day the father dies and inherits the house to his two sons.
- The first son claims that his expenses must be repaid before splitting the inheritance money.
According to the Halacha that the expenses for honoring parents are on the parents themselves, Is he right?
