I bought a second-hand building this summer, and now I have to pay the heating bill. People say that I owed two years before, and now I have to make up for it. If I find the former owner, what will he do? I just finished a case like this:

My situation is that the original owner signed a fee of more than 70,000 yuan after trading with my client, and did not inform my client. Now that the transfer transaction is completed, my client's house is for sale, and the property requires us to settle the house payment before selling. Otherwise, it will not be delivered!

In this case, you can completely ignore the number of contracts signed before, and the previous fees have nothing to do with you. If you don't provide heating, you can sue them directly in court, or you can sue the original owner for hurting you! Germans!
