If a dispute arises between the parties to a sale over entitlement to money that is being held in escrow by a broker, the broker shall retain the money in escrow until the dispute is resolved. If resolution of the dispute appears remote without legal action, the broker may, following 30 days' notice to the parties, petition the Philadelphia Court of Common Pleas to interplead the rival claimants.
