Often, yes, but the will and estate documents determine who can sign and whether a court order is needed. If the will gives an appointed executor—the person administering the estate—the power to sell, that executor generally can sign without a separate court order (Ohio Rev. Code §2113.39). If it does not, a consent option may be available only if the will does not forbid it, the surviving spouse and all beneficiaries named in the will—or all heirs if there is no will—consent in writing, the consents are filed with probate court, and the price is at least 80% of the house’s appraised value in the approved inventory. That option is unavailable if the surviving spouse or any beneficiary or heir is under 18 (Ohio Rev. Code §2127.011). A recorded transfer-on-death designation may let a beneficiary sell outside probate after recording an affidavit (Ohio Rev. Code §§5302.22, 5302.222). The appointment, will, deed, and any court order control who can sign.
