Inheritance tax from seller with no mortgage insurance from 1999

[David Park]

We are looking to buy this property but the inheritance tax was never paid to the Commonwealth of Pa when he sold the house in 1999. The buyer from 1999 did not get title insurance when they purchased the house. Do we need to get in touch with the seller from 1999 or his relatives to see how they handled the payment of the inheritance tax? How would we buy this house?

Thanks in advance for the advice!
