HRS §560:3-713
When the estate manager can buy estate property
This section says that if the person managing an estate (the personal representative) buys estate property or does a deal where they have a conflict of interest, that deal can be canceled by anyone with an interest in the estate. But the deal is okay if the will or a contract allowed it, or if a court approved it after notice.
