Key facts: Under 20 Pa. C.S. § 3102, personal representatives have fiduciary duties to identify and address all tax liens on estate property; municipal tax claims in Pennsylvania are governed by the Municipal Claims and Tax Liens Act and enjoy priority status; tax liens survive the death of the property owner and become estate obligations; Pennsylvania estates exceeding the $50,000 threshold follow formal probate procedures; and beneficiaries receiving lien-encumbered property inherit the encumbrance and must satisfy the lien to obtain clear title.
