Can an executor be a beneficiary?

There is nothing to prevent an executor from also being a beneficiary of the will and in fact it is very common. Usually, being given the responsibility of administering a person’s estate means the executor is a close relative or friend of the deceased. It wouldn’t be unusual for that class of persons to also benefit from the will.

Safeguards are provided by the legal rules in place and the duty placed on executors to act in good faith.
