A power of sale clause skips the courthouse
A specific devise overrides even a general power of sale
If the will names a specific beneficiary to inherit the house directly (a "specific devise"), the executor has no authority to sell that parcel — even with a general power-of-sale clause elsewhere in the will — without the named beneficiary's written consent or a separate court order.
A tiered statutory commission on the gross estate
SCPA §2307 sets the fiduciary's commission at 5% of the first $100,000, 4% of the next $200,000, 3% of the next $700,000, 2.5% of the next $4 million, and 2% above that — calculated on gross value, with debts and taxes not subtracted.
Specifically devised property earns no commission at all
Real estate or other property "turned over" directly to a named beneficiary is not commissionable — ownership vests in that beneficiary by operation of law at the moment of death, not through any action by the executor.
