In York v. Roach, 163 Pa. Commw. 58, 639 A.2d 1291 (Pa. Cmwlth. 1994) the property owner tendered an amount in excess of twenty-five percent of the back taxes due, which the tax claim bureau accepted and applied to back taxes but did not inform the owners that they qualified for a stay of the tax sale under Section 603 of the Tax Sale Law. The Court held that the tax claim bureau had an affirmative duty to advise the owner of the option to enter into an installment agreement.
