Quick answer: generally no — the personal representative already has statutory power to sell. A court order becomes necessary only if the sale contravenes the will, or the house was specifically devised without sale authority. Run your own numbers in the Oregon probate real estate sale calculator.
The power to sell exists from the start
Two narrow exceptions require a hearing
Exercising the power to sell is improper — requiring notice, a hearing, and a court order — if the sale is in contravention of the will's provisions, or if the property is specifically devised and the will doesn't authorize its sale. Outside those two situations, the sale proceeds on the representative's own authority.
Vesting at death doesn't unlock a sale by the heirs alone
Title to Oregon real property vests in the heirs or devisees at the moment of death, but it remains subject to the personal representative's possession and control during administration — heirs generally can't sell on their own while the estate is open, regardless of who technically owns the property.
A simple estate affidavit is a separate path entirely
For qualifying smaller estates, the affiant plus every heir or devisee with a stake in a specific parcel can join the conveyance directly, under the simple estate affidavit process — no personal representative, and no probate court sale authority question, needs to come up at all.
Title companies check authority, not just ownership
A title company insuring the sale wants proof of actual legal authority to sign the deed — Letters Testamentary or Administration for a probate estate, the affidavit plus required joinders for a simple-estate sale, or the relevant trust, survivorship, or transfer-on-death paperwork.
A local probate attorney can review your estate — many offer a free consultation.
Multnomah, Washington, and Clackamas County each process these sales through their own Circuit Court, but ORS 114.325's default sale power applies identically statewide.
