Sale under will; exercise of power; tax liens and claims

(a) If a will authorizes the executor to sell any property, the executor, or an administrator with the will annexed, may exercise such power without any order of the district court, unless the will provides otherwise. Subject to the limitations contained in K.S.A. 59-704, and amendments thereto, such power may be exercised at any time except when a proceeding to set aside or contest the will or to probate a later will of the decedent is pending. (b) Every conveyance of real estate of a decedent to a bona fide purchaser, pursuant to the authority of this section, shall transfer such real estate free and clear from liens and claims of all creditors of the decedent of the estate of the decedent and of the heirs, devisees and legatees of the decedent and any such liens or claims shall be transferred to the proceeds of such sale received by the executor or administrator making the same but such transferral shall not affect tax liens against the estate.
