How to solve the problem that the landlord didn't pay the property fee before buying a second-hand house?

Legal analysis: when the property right is transferred, the owner or user of the property should settle the property service fee or property service fund. The property should have settled the property fee with the former owner before the transaction was completed. If there is no need to settle, ask the original owner for it.

Legal basis: People's Republic of China (PRC) City Real Estate Management Law.

Article 36 When transferring or mortgaging real estate, the parties concerned shall register the ownership in accordance with the provisions of Chapter V of this Law.

Article 62 When a real estate is mortgaged, it shall be registered with the department designated by the local people's government at or above the county level. Where the land use right and house ownership are obtained due to the disposal of mortgaged real estate, the transfer registration shall be handled in accordance with the provisions of this chapter.
