Pennsylvania Statutes Title 68 P.S. Real and Personal Property § 161. Perpetual ground rents not to be created

From and after the passage of this act, whenever a deed or other instrument of writing conveying real estate shall be made, wherein shall be contained a reservation of ground rent, to become perpetual upon the failure of the purchaser to comply with the conditions therein contained, no such covenant or condition shall be so construed as to make the said ground rent a perpetual encumbrance upon the said real estate; but it shall and may be lawful for the purchaser thereof, at any time after the said ground rent shall have fallen due, to pay the full amount of the same, and such payment shall be a complete discharge of such real estate from the encumbrance aforesaid.
