In In re Return of the McKean County Tax Claim Bureau, 677 A.2d 1325 (Pa. Cmwlth. 1996), the Court set aside a tax sale because the tax claim bureau's notice to the taxpayers on how to eliminate their tax delinquency was ambiguous. Further, the fact that a property owner has actual notice of an impending tax sale does not relieve the tax claim bureau of the need to give each of the three types of notices required by statute; if it does not do so, the sale is invalidated.
