What should I do if the purchase contract does not match the property?

The purchase contract is inconsistent with the property owner, and the seller who may sign the contract has no right to dispose of it, and the real property owner does not know about it. At the same time, real homeowners are reluctant to sell their houses. At this time, he can ask the seller to refund the house payment and compensate for the losses. If the other party commits fraud, you can call the police. According to Article 3 of the Supreme People's Court's Interpretation on Applicable Legal Issues in the Trial of Disputes over Sales Contracts, if a party claims that the contract is invalid on the grounds that the seller has no ownership or disposition right to the subject matter at the time of conclusion, the people's court will not support it. If the buyer asks the seller to bear the liability for breach of contract or terminate the contract and claim damages because the seller has not obtained the ownership or disposal right, the people's court shall support it.
