If an executor has any interest that can possibly interfere with the estate's administration, the court may remove him/her from the position. Notably, being a beneficiary and an executor at the same time is not enough for the court to declare a conflict of interest. In most cases, inheritors take good care of the assets because they have a strong incentive to do so. An excellent example is an executor that guaranteed a loan to the estate, and the borrower isn't likely to repay it.
